How's Thc crystalline 99.96% made?
- Thread starter Blarry93

I believe that ends in honey oil, I'm looking for actual crystal form. The comments on all the pics/videos say it looks identical to meth.
Nvm I just found a article about suger I'll figure it out from there

Lol goodluck...it is chromatography and azetropic distillation...you posted in wrong section

you gotta work at a photomat, just to get the right schtuff to do it.
powdered alcohol exists too. neither is what you expect.
snort hash instead!!!

You really are a moron, aren't you?
Not only does any of this have NOTHING to do with photography! NONE of the chemicals used in old school film developing and printing have ANYTHING to do with these process's !!!

I think he's more of a troll than a moron, as it seems he's trying to stir the pot
seen other posts saying he's likely a reincarnation of a previously suspended member

They use chromatography but an easier way is crystallization with an amine. The best amine for the purpose is the one named in this quote from US 2015/0038567 A1. This example is for CBD acid but it works the same with THC acid. You don't need to use the countercurrent process mentioned either. I guess after the procedure described you would have to change the THCA back to non-amine form by adding an acid.
"2 kg of flowering tops of industrial hemp (e.g. of the
variety Fedora 19, but others are also possible) dried at below
30° C. are extracted portionwise with cold (<15° C.) isopro
panol by the countercurrent process. The extract obtained is
concentrated under reduced pressure at max. 40° C. to a
volume of ca. 400 ml. This concentrate is treated 12 g of
dicyclohexylamine and stirred for 24 hrs at 0° C. The dicy
clohexylamine salt of cannabidiolic acid crystallizes, and is
suction filtered off. Rinsing with 80 ml of ice-cold isopro
panol and drying under vacuum gives 22.4 g of cream-colored
salt."

o ya? talk to skunkpharm about acetic acid, or try google mate, and the decaf too
https://www.rollitup.org/t/converting-thc-to-its-acetate-makes-it-psychedelic.321275/
acetic anhydride
its used to make crystallized THC, and also is used in...whaddya know
"Acetic anhydride, or ethanoic anhydride, is the chemical compound with the formula (CH3CO)2O. Commonly abbreviated Ac2O, it is the simplest isolable anhydride of a carboxylic acid and is widely used .... is a component of photographic film and other coated materials, and is used in the manufacture of cigarette filters." wikipedeia
there may be other ways to crystallize thc , but this is one according to erowid, and more.

do you
know anything of the process I speak of?

They keep the details of the electrolytic procedure secret. If you mean the THC acetate thing, that's a different compound. It's not THCA. The patent I cited just recommends crystallization to purify THCA.

I understand that, but do you know of the crystal thc acetate I am speaking of? I know its rare, illegal, hardly seen by anyone these days.

THC with an ester attached to it? Do people shoot that stuff?

Yeah but it's not more potent than THC as is sometimes reported. It's actually less potent so not much reason to make it. Besides, you need acetic anhydride which is watched by the DEA because it's used to make heroin. The easiest pure compounds to extract or make are THCA and CBD. CBD is a crystalline solid at room temperature, unlike THC.

The chemicals needed to produce crystalline Δ9 THCA are.........
Acetic Acid
Hexane
Chloroform
Dichloromethane
Methanol
Pentane
The procedure to produce crystalline Δ9 THCA at a purity of greater than 98% is........
"A method of producing Δ9 THCA crystals comprising:
i) preparing an extract of the cannabis plant material with 0.1% v/v acetic acid in hexane,
ii) filtering the resultant extract and removing solvent from the filtrate by rotary evaporation to form an extract enriched in Δ9 THCA,
iii) passing a solution of the resulting Δ9 tetrahydrocannabinolic acid (Δ9 THCA) enriched extract through a column packed with Sephadex-LH20™, eluting with 2:1 chloroform/dichloromethane,
iv) collecting Δ9 THCA rich fractions eluted from the column and removing solvent by rotary evaporation,
v) re-dissolving the crude Δ9 THCA obtained in step iv) in methanol, removing insoluble residue by filtration and removing solvent from the filtrate by rotary evaporation, and
vi) re-dissolving the product of step v) in pentane, removing insoluble residue by filtration and removing solvent from the filtrate by rotary evaporation to produce said Δ9 THCA crystals."
And the patent is here........
