Introduction
You now have in your hands a complete and comprehensive guide to home oil
extraction using a quick, simple, efficient and safe method of extraction from
plant materials. In these pages are instructions for making some of the most
potent oil anyone has ever smoked. It's easy, because we tell you exactly how to
make it, step by step, with common laboratory equipment. We will tell you what
safety precautions you should follow, and how to obtain the necessary materials.
Your oil is extracted with petroleum ether, a common solvent that is easily
obtainable. It is not a real ether, but the name comes from early chemistry
days. It is a mixture of isomers of hexane (low boiling hydrocarbons). Isomers
are molecules with the same type and number of atoms, but which differ in their
spatial arrangement. Petroleum ether is very similar to the components of
gasoline and must be treated with the exact same care. You must be extremely
careful when you use petroleum ether for it is very flammable and can explode if
the vapors are heated in a closed system (we will have more on that later). You
will see that we emphasise safety throughout the book. If you follow these
instructions you will be able to safely extract all the oil you want without
fear of harm. Please follow them carefully. Since we do not recommend the use of
flame or heating coil for the extraction, the danger of fire is greatly reduced.
Please read the section on safety carefully, and have anyone who is to
participate read it also.
The amount of oil you get, and the color of the oil will vary, depending upon
the pot you use. Amounts vary from plant to plant. Quality remains constant.
Unlike many oil machines on the market, we do not use alcohol for the
extraction. Alcohol extracts the oil just as petroleum ether does, but not as
efficiently. Alcohol also extracts chlorophyll plus simple and complex sugars,
while petroleum ether does not. After the extraction process your plant material
will look the same as before, but will not be potent since almost all of the
active components have been removed.
Concerning the safety Checklist
Safety is of extreme importance when making oil. The extraction is safe, but
in order for it to be so, one must follow all instructions and precautions.
Carefully read the safety precautions in this manual to insure the production of
high quality oil without injury to yourselves or others. Make sure that you read
the entire text, paying special attention to safety precautions, and
instructions for care and storage of petroleum ether. No matter how competent
you feel, do not take anything for granted. Do not overlook any precautions, and
do not allow anyone who has not read this book or does not understand all safety
precautions to participate, interfere or be present during production. It is
absolutely necessary to observe all points of safety. So do yourself a favour,
and take the time.
The safety checklist will be referred to throughout the book, so it would be
wise to read it over now. the checklist, as well as the entire manual, should be
read and completely understood before beginning the process. We repeat, DO NOT
IGNORE THE SAFETY PRECAUTIONS!.
Procedure for making the oil
Before starting the extraction process, make sure you have read the whole
book twice, carefully. Be sure you have studied the section on safety. Do not
allow anyone to assist, observe or interfere unless they have read and
understand the safety precautions.
The following steps are for initial extraction.
REFLUX
To set up the reflux you need one ringstand, one condenser, one round bottom
flask, two clamps and silicon grease.
Place the ring stand on a stable surface. Put one clamp on the flask's neck
and clamp it to the stand. Leave enough space underneath the flask to place a
pan of hat water and to be able to remove the pan to add fresh hot water. The
water should be at neck level on the flask.
Now carefully clamp you condenser into place (use a small amount of silicon
grease to give an airtight seal). Be careful with the condenser, as it is
probably the most expensive piece of equipment you have bought. Connect the hose
that carries the cold water to the BOTTOM nipple on the condenser. Connect a
second hose to the top connector on the condenser, and let the other end drain
to the sink. Carefully fill the condenser with cold water. Make sure your
connections are tight. Also, never seal the top of the condenser when refluxing.
When you are refluxing, pressure is kept at a minimum by the condensing of the
hot vapors, but some pressure exists. If vapors escape, reduce the heat by
adding some cold water to the hot water in the pan. Do not begin heating the
flask until all equipment is set up, and all petroleum ether is put away.
1. Remove flask and place material to be refluxed into it. Leave about two
inches of space between top of material and the bottom of the flask's neck.
2. Take the petroleum ether from the refrigerator and add enough of it to the
flask containing the plant material so that the petroleum ether just covers the
material.
3. After you have put the petroleum ether back in the refrigerator, connect
the flask that was just filled to the bottom of the condenser. The flask should
be secured by a ring clamp to the ringstand. Make sure the condenser and flask
fit well. Use silicon grease for a tight seal.
4. Turn on the cold water attached to the condenser
5. Put warm water in a bowl and place it so that the flask is submerged to
about the level of the petroleum ether. Use book(s) to elevate the hot water
bath in order to adjust temperatures without adjusting the height or position of
the flask. The reflux process will begin as soon as the petroleum ether starts
to boil. The water bath temperature should be around 35C or 110F. UNDER NO
CONDITIONS SHOULD YOU HEAT THE WATER WHILE REFLUXING. Always get your hot water
from another room or use hot tap water. Do not use water that is too hot to
touch - it will be too hot for safe refluxing and could be dangerous.
6. A steady even boil not reaching into the neck of the flask is what is
desired. If it is boiling too fast (boiling into the neck of the flask) remove
water and cool it to reduce the rate of boil. If it is not boiling slowly and
evenly, add warmer water to the bath.
7. Allow refluxing to continue for 45 minutes.
FILTERING THE PLANT MATERIAL
1. After refluxing is completed you may remove the warm water and replace it
with ice water. This cools the ether, so it will not evaporate too quickly
during the filtering process.
2. Fold filter into a cone shape. Hold filter in top of pyrex beaker.
3. Remove flask from condenser and bath. Carefully pour petroleum ether
through the filter (be extremely careful not to spill any ether). DO ALL WORK IN
A WELL VENTILATED AREA AWAY FROM ALL FLAMES, SPARKS OR HEAT. The filter catches
all small pieces of plant material and seeds. Do not get plant material in the
filtered solution.
4. Take petroleum ether from the refrigerator. Pour a small amount of
petroleum ether into the flask with plant material. Shake well and pour through
filter into the beaker with the rest of solution. (This insures that you are not
losing any oil). Put the petroleum ether and the refluxed solution (covered) in
the refrigerator.
5. Not all of the plant material will come out of the flask when you pour for
filtering. The remainder may be removed with tweezers, forceps or by gently
shaking the flask upside down. Be careful not to scratch the ground glass if you
remove the material with any tools. Wrap the treated plant material in paper
towels and place it outside in a well ventilated area where the petroleum ether
may evaporate safely. Do not place it near fire, heat source or sparks. This
material will dry within an hour and should be disposed of properly.
OPTIONAL FOR FURTHER PURITY
If you are a connoisseur of fine oil, and do not mind a few minutes extra
work, and a few dollars more of equipment, then you will want to further purify
and concentrate your oil
First, immediately following the filtration, mix about 2-3 grams of finely
ground activated charcoal to your extracted solution and stir well. Make sure
the solution of petroleum ether and oil is cold before starting this process.
Re-filter this mixture. If all the charcoal has not been removed, repeat the
filtration. It might be advisable to use regular lab filtration paper for this
step. After filtering out the charcoal, you will notice the solution is less
colored. (Don't worry, all the oil is still there. You have only removed the
impurities.)
Secondly you should water-wash the solution. the essential oils are not water
soluble while some impurities are both soluble in water and petroleum ether.
Since petroleum ether and water do not mix together you can place them in the
same container together and shake well and they will separate. The water soluble
impurities in the petroleum ether will dissolve in the water, and then the two
solvents will separate, leaving the oil in the petroleum ether and the
impurities in the water.
The container used for this mixing of solvents is a separatory funnel. This
is a clear, pear-shaped container. Simply pour the petroleum ether in the top to
the half full level, and add several inches of water. Now close the cap, point
the barrel away from your face and shake lightly. Open the stopcock to release
any pressure that has accumulated inside. Close the stopcock and repeat the
process, releasing the pressure between each shaking. Repeat until opening the
stopcock releases no pressure. Now place the funnel on the ring clamp and remove
the stopper. You will notice an interface. The bottom level is water, and the
top petroleum ether. As the interface moves down, reduce the flow until the
level reaches the bottom, and then quickly turn it off. You have now separated
the two liquids. Using this clean and pure solution, go on to the distillation.
DISTILLATION
To set up the distillation, you need 3 ring stands, 5 clamps, 2 round bottom
ground glass boiling flasks, 1 elbow connector with vacuum outlet, 1 elbow
connector without vacuum, one condenser, silicon grease, plastic tubing and
aspirator assembly.
Set up the ring stands in position. The flask with the filtered solution
(flask A) requires the elbow connector without the vacuum outlet (nipple). The
flask and the elbow joints should be independently supported by clamps connected
to the ringstand. After attaching and positioning these to the ringstand, attach
the other flask and the elbow with vacuum outlet (nipple) to a separate
ringstand. Make sure that both flasks are tightly connected with the elbow
joints and that each part is independently supported by separate clamps. The
condenser should then be connected to the center ringstand. Allow sufficient
room beneath flask B to remove the ice bath in order to add more ice if
necessary. Once you have found an appropriate height for the positioning of
flask B, you may connect the condenser to flask B. Now you may position flask A
and connect it to the other end of the condenser thus closing the system except
for the vacuum. You will have to adjust the positioning of flask A and the
condenser to get a tight fit and to stabilize the distillation set up. N.B. THE
CONDENSER MUST BE ON A SLOPE WITH FLASK A AT THE HIGHER END. Connect the hose
from the water source to the lower nipple on the condenser which should be the
same end as flask B. Connect the hose for the draining off of the water to the
upper nipple. Connect the aspirator to the sink faucet and then connect the
vacuum hose from the aspirator to the water trap. Then connect the water trap to
the nipple on the elbow joint. Now turn on the water to be sure that the system
is connected properly. Once the water is flowing smoothly, almost, if not all
air should leave the condenser. Before proceeding make sure that your system is
connected properly and is stable. (For diagrams etc see a chemistry textbook or
similar on distillation).
To prepare for distillation, place ice bath around flask B up to the neck
bottom. This cools the distilled ether and keeps it from being further moved
into water trap by the vacuum.
Then place the warm water bath(35C or 110F) around flask A, about 1 inch from
bottom of flask neck. The petroleum ether will quickly begin to boil. Do not
allow the solution to boil so vigorously that it boils up into the neck of the
flask or condenser. If it does, reduce the temperature by adding cold water to
the pan. As hot vapors rise they pass through the adapter and into the
condenser. Here the vapor condenses into droplets which collect and roll down to
flask B where the ice water keeps it cool and a liquid. Note: This is only
petroleum ether, not oil. The oil stays in the heated solution because it's
boiling point is much higher than petroleum ether. Only ether boils away and
only its vapors travel into the condenser. Eventually the ether will be entirely
separated from the oil. As the evaporation process continues it causes the
temperature of the solution in flask A to drop. This will slow the process of
distillation somewhat but do not raise the temperature of the water bath. Just
continue using hot tap water.
As the volume decreases in flask A you will notice the color of the solution
darkening. As the ratio of oil to petroleum ether increases, the oil will become
increasingly visible. the oil will become more concentrated and form a thick
residue in the bottom of the flask. When all the ether has appeared to have
boiled away, continue distilling for 5 to 10 minutes to ensure pure oil. Remove
the warm water. Turn off water on aspirator slowly. Remove ice water bath and
flask B. Pour ether back into original container and place in refrigerator for
future use. It may be necessary to use the separatory funnel to remove any water
that is mixed with the ether.
Replace empty flask B back in position. Remove flask A making sure all
visible petroleum ether is gone. Allow to cool. Add about 25ml of ethanol or
isopropyl alcohol to flask A with the oil. Replace flask A in position, turn on
water, and repeat the distillation process. This removes any toxic impurities
that may be present. When all the alcohol is gone from flask A, heat 5 to 10
minutes more to insure the purity of your oil. Dispose of alcohol in flask B.
At this time you have oil inside flask A. To remove it, first make sure all
the ether and alcohol has been removed, then place lower portion of the flask
into boiling water. The oil will become very thin and can be poured from the
flask. You can pour the oil directly into a vial or onto aluminum foil, where it
will cool and can be transferred in a more solid form.
There will be some oil left in the flask You can leave it there where it will
mix with the next batch, or you can recover it if you do not plan to make any
oil in the near future. If one wishes to remove the remaining oil, carefully
pour 10-20 ml alcohol into cooled flask and carefully swirl it around and
dissolve all remaining oil. Pour this into a round bottom corning ware dish.
Place it in a well ventilated area and let it evaporate. After the alcohol
evaporates, using a rounded rubber spatula, scrape out the oil and place it with
the rest.
Now you have your oil and are dying to test it. WAIT!. First clean all the
equipment with petroleum ether and dispose of the ether used. Disconnect all
glass ware and empty all containers.
