Hi ya'll!
In response to a PM asking for basic procedure, we’ve only made three runs so far and are still shaking out the process but here is what we’ve done so far.
Disclaimer: Acetic anhydride and sulfuric acid are both highly toxic to breath and acetic anhydride is flammable, so good standard practice lab techniques for toxic flammable components are required. IE: Good ventilation free of ignition sources.
Acetic anhydride is basically vinegar with all the water removed, and reacts violently with water. Keep it away from water unless you are doing it on purpose.
Using an Erlenmeyer flask, weigh out and add the cannabis oil to the nearest 0.01 gram.
Measure out and add 2.5 grams of acetic anhydride per gram of cannabis oil.
Measure out and add sulfuric acid at 5% of the combined volume of acetic anhydride and oil.
Swirl the flask continuously for about five minutes and then cook in a water bath at 70/80C (158/176F), stirring the liquid occasionally for about 30 minutes.
After 30 minutes, cautiously add hot deionized water drop by drop at a ration of 2 ml per 5 ml of acetic anhydride. This reacts any un-reacted acetic anhydride.
Put solution in ice bath for about 15 minutes to cool.
Saturate dionized water with sodium chloride (table) salt until no more will dissolve. Add 10X combined volume of all ingredients.
You now have cannabis acetate.
Add hexane equal to 10X the volume of the combined liquids, excepting water. Shake well, and put in a separatory funnel. Allow to separate and bleed off the lower layers, leaving the enriched hexane layer.
Add additional dionized water and bleed off after separation to wash out the extract.
Cook off the hexane in a hot oil bath at ~250F and when it is bubble free, add ethanol to wash it out of the container and return to hot oil bath to cook off the alcohol and purge the residual hexane.
Smell the results and wash again with ethanol and cook off if necessary to get rid of the hexane smell and taste.
Bon appetite brothers and sisters, in that we continue to play with the procedure and have to date produced three different extractions, fortunately all impressive, yet all slightly different and we are still working out the fine details.
I will post the final results as those are available.
Hee, hee, hee, snicker, snark, snort…………
