Direct isomerization of THC to produce purest extract

Direct isomerization

Sometimes if pot is totally rank and crappy, or you're dealing with a bunch of roaches, trimmings, or some other inferior source of THC it is desirable to go well beyond what a simple volatile solvent or super critical fluid extraction can do. You want to convert all those free available cannibidiols into more potent THC analogs and cannabinols.

This technique also will render a fully decarboxylized end product, as well as destroying many terpenes and aromatics which can improve or destroy a product depending on the original quality. It is important to understand this is not a full conversion to ƒ´9-THC, but to THC analogs and more active cannibidiols, and is included in this discussion more as an educational exercise. Basic isomerization takes place with a quick reflux of your cannabinoids in the presence of any H+ source (acid).

1. Treat your stuff as if it were a volatile solvent or critical fluid extraction.
2. With the remaining resin, dissolve it in a non-polar solvent. Be sure to use one that separates easily from water such as naphia or white gas.
3. Treat this mixture with sulphuric or hydrochloric acid until a pH around 1-2 is reached (approximately one drop of concentrated acid per gram of extract).
4. Place this in a reflux apparatus and cook it for about an hour. In case you¡¦re not familiar this is basically just Pyrex breaker with a large looped tube plugged into the top. This will cause the solution inside to be exposed to elevated pressures as well as temperatures, as well as preserving all of the original contents. Simply simply boiling the mixture in a small strong covered vessel can mimic it.
5. Wash what¡¦s left with water, keep the oil layer.
6. Neutralize your mix (bring it to pH 7.0) with a little Sodium Hydroxide solution (pH 9.0) or baking soda then rewash it with water. Save the oil layer again.
7. Allow your oil to evaporate and you should be left with a sticky amber liquid that contains almost pure THC.

I would recommend an extraction for a starting point, since if you start clean your product can only get much better. Once you¡¦ve obtained nearly pure THC, converting it to an acetate is supposed to produce more psychedelic like effects.

More THC analog modifications can be made (to yield pure ƒ´9 or ƒ´6 THC), but generally the consumption of the original products in these reactions makes them hardly worth while (usually 5-20% yeild, so it may be half as psychoactive but you have 5 times as much of it in the beginning).
