Cannabis Alchemy

[BullDogUK]

Howdy folks

DemonPigeon recently got hold of a number of cannabis related books, including D. Gold's Cannabis Alchemy. Whilst I do love this book, I'm currently incapable of procuring sufficient quantities of cannabis for this kind of experimentation so thought I'd share it with the lovely community here!

So first up is a method of purifying cannabis oil.

The oil is dissolved in 5x it's weight in iso-alcohol and poured into an equal volume of water inside a screw top jar. A volume of petroleum ether equal to 1/4 of the water/alcohol mix (or 1/2 of the original volumes of water/alcohol use) is added into this jar. The screw top is then tightened, the jar inverted and reverted to mix the material and the screw top removed to prevent explosive build up of pressure. This is repeated 25 times and the jar allowed to rest for ~30 minutes.

Over this time the mixture of liquids will separate into three distinct layers, the bottom containing a cannabis oil/alcohol/water mix, a middle emulsion layer consisting of waxes, ether and air bubles and a top layer of ether and purified oil. A stopper is then applied with two tubes of differing length. One tube must extend only a few centimeters into the jar whilst the other must extend into the ether/oil layer but not into either of the other, lower layers. A collection jug is held at a lower point than the ether/oil solution in the jar and connected to the longer tube via rubber hosing. Air pressure is then applied gently via the shorter tube to begin siphoning of the ether/oil layer (see fig 1). Once extraction is completed, further petroleum ether can be added and the process repeated until the ether/oil layer becomes clear.

Once extracted from the jar, the petroleum ether can be removed by gently placing the solution in a water bath at 60C (140F). Once the oil is isolated should be put in a bath of boiling water to remove any impurities.

Always wondered about this book. Have never had an opportunity to read it. Thanks for sharing!

I have it in my library and also recommend Marijuana Chemistry by Michael Starks.

Golds water wash technique is similar to our hexane and brine wash, but his THC-O-A (THC Acetate) formula appears to have been adapted from heroin manufacture, and is off in proportions for cannabis.

I have to agree there. What do you think of his method for CBD isomerization to THC? I was also wondering if the reverse reaction would be possible. I'll be putting up a summary of the process soon and will have a look into the reverse anyway.

We've Isomerized CBD to THC, but alas, not the other way around.

It is easy enough to do, but the results were not impressive. The recreational strain that we isomerized, had low CBD to start with, and THC by itself is rather flat in effect.

As a measure of how impressed we were, we only isomerized once and continue to make THC-O-A.

Here is a picture of our only isomerization experiment, beside the original oil that it was made from. The original oil had been winterized and filtered to 0.2 microns prior to isomerizing.

The divots are sample pick marks. The small specs in the original sample are gnats, after the beaker was inadvertently left uncovered. They are drawn to the smell, like bees to honey.

Ah well, I imagined that would be the case. From the sounds of it, the strains back in the day must have had a much higher CBD content. I was more interested in if the reverse would be possible frankly as CBD seems to be a more interesting/beneficial compound.

How do you go about performing the acetylation? Does it really make much of a difference? I have the problem of not wanting to create a home-made fume cupboard in order to work with maybe a gram or two of oil -_-

The THC-O-Acetate has thus far been enthusiastically embraced by us'n and all the test panel members and students who have sampled it.

It is a fast pain reliever and mood elevator for PTSD.

Having said that, it hasn't blown the socks off anyone yet, nor left any drooling idiots, or paniced wild folks in its wake either.

As a practical measurement, we've made it in our last two overbooked alchemy classes, and the enthusiastic response from the bright students testing it, suggests that most of them will be following up with making their own soon.

A few years back, not that many really, that book made living with commercial bricked Mexican cannabis a lot easier. Been nice to see how it's content has stood the tests of time.

Isomerise

Isomerise

Hi, I am interestet about this methods. Can somebody post a complede methode to make strong hash? It is not importand that it is realy 100% THC. It is very importand that it is very easy to make and not poison.

I thought about 20% minimum. But the weed i take can in the original not make high.

I thought about ''acid sulfur'' to isomerise the CBD or what ever is inside the Weed to THC-Δ-9.

I found ths method:

THC Isomerization - convert industrial hemp in potent hash oil
Moin, I follow the instructions also ever worked and it works.
At first hashish oil ( extract) from about 20 pull - 30g industrial hemp . Either cook with butane gas ( better result but dangerous ) or in 1/2 liter of alcohol for 2 hours under reflux and filtering off .
If you 've made ​​hash oil with butane, you have to solve this in about 300 - 500ml alcohol.
Then add a ca 10 ml of conc. Sulfuric acid are added * .

* This converted mentally inactive THC isomers and related substances such as cannabidiol in akitve THC isomers around . *
Then you cook it again for 4-5 hours under reflux and allowed to cool.
Now slowly soda is added until it stops bubbling in the addition.
Then there's the mixer through a coffee filter and the filtrate is cooled down to about 5 ° C in the refrigerator.
Then you take a water-insoluble solvent such as Benzene, ether , chloroform, surgical spirit , Toluol , dichloromethane, xylene ( Please benzene, is Carcinogenic , if one net Removes right!) Or what you've just in the house and heated it to more than 30 ° C.
Then you are about 150ml of it on the filtrate and shake well for 30 sec through .
Then added 500ml of ice cold water , stir and let it stand for 10 minutes .
There , two layers form in the liquid. - The water will absorb the alcohol.
THC migrates into the layer containing the water-insoluble solvent. -
Separate the two layers of each other (if you have not a separating funnel , let you come up with something ) . The water / alcohol layer (lower layer) can be discarded.
The other layer is carefully evaporated in a shallow dish ( water bath is optimal, but beware, the vapors of lsg.m. are flammable! )
What remains is the hash oil.
( on ​​the same principle provide German pharmaceutical company THC their preparations as dronabinol ago).



If you post an complete method, please don't forget to give a list of all the things you need to do it. All the things should be possible to buy on the free market.

Thanks.

You don't need an acid/base extraction to make strong hash. A simple butane extraction with a vacuum purge will get you strong hash oil that's easy to make and not poison. A QWISO or QWET extraction can get you a similar quality oil. The sticky threads here have all the info you need to get started. The Hashish section has all the info you need if you'd rather make hash without solvents.
