How's Thc crystalline 99.96% made?

[Dr. Who]

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.

REALLY? Gosh! So how does cellulose acetate (the plastic film) tie in with ANY chemicals you might find in a "photomat".....I haven't even seen a photomat in years! Your stupid is showing !!!

Let me say this again, "NONE of the chemicals used in old school film developing and printing have ANYTHING to do with these process's !!!"

How about the fact that Acetic anhydride possession in the US....is tantamount to Heroin possession and the DEA heavily regulates it!

read above my friend. anyhdride is a component of photography, like try google or something man, I cant do it all for you. I posted the facts. perhaps this is not the way ops mix becomes a crystal but it is how a thc crystal can be made. accept it, the facts have been stated above. move along now, I'm no threat to you or your efforts here

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........

The problem with chromatography is that it's kind of a lot of messing around.

 

[cool2burn]

Honestly i had the stuff and it was almost impossible to work with it is so pure even when you freeze it it becomes almost like a thick syrup i had issues dabing it so i put it in my OG pen and it smoked good.

 

[Fadedawg]

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.

We included making THC Acetate in our cannabis alchemy classes, using the basic process for making aspirin, but Pharmer Joe has just recently started making THCa and CBD crystals. I've personally never made either, only sampled his crystals and used them to make Royal Jelly, using Clear and THCa crystal.

We always tested what we made in class, using a volunteer test panel of the students themselves, and without fail everyone liked the THC Acetate. The most common comment was, "oh wow", not because it was so overpowering, but because of how fast it comes on.

It produces a different state of altered awareness, subtly different in that it includes color shifts and other sensory changes similar to shroms, replete with a general feeling of peace and harmony.

We made it from an Absolute, but one thing that we never sorted out, was shelf life. In class it wasn't a problem, because there was never much left, but just sitting around it starts to revert back to acetic acid, and develops a bite.

Here is how we did it: https://skunkpharmresearch.com/thc-acetate/

I just put THCa crystal acetate on the to do list, to see if using crystal solves the stability problem.

It is a component in making the plastic that the film base is made from. There is NONE of it in any photography lab or dark room!

You directly implied that's where you can find it! AND continued to hold that position!

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!!!

YOUR WRONG!

 

[gwpharms]

Anhydride is easy to make. As is sodium acetate, acetic acid, acetamide, acetonitrile,
Its the circle of life. One thing makes the other and the byproducts are even useful.
None of us would be here if not for acidic acid that's for sure. It's as important as water is to life

anhydride. Glacial acetic acid and acetonitrile and hcl gas. Stitchiometric ratio but excess glacial is ok. There's an old paper on it somewhere.

You can distill your own glacial acetic acid but it's probably easier to just buy it it is not watched and very useful for many things.
Yes it was used in photography as well as Palladium and many other inorganics. When they existed photo stores where the chemist best friend. Mine closed in 1998. Sad day
But this is the only real Pathway to Pure THC all this fractional distillation phenomenon is really quite absurd.
I really wouldn't recommend thc acetate or crystallization for the at home do-it-yourselfer. Many of the things you would be doing are akin to some pretty clandestine chemistry and can be dangerous
But this is a pathway pharmaceutical companies use to get pure THC and eventually the metabolic THC 11. 2 things you'll probably never see in a pharmaceutical lab that is doing this kind of work.
Butane extractors
fractional distillation apparatus for cannabis oil.
There's really no reason the average person would need to do this. Enjoy the 70-80% extracts that are already being made. Pure thc isnt what most people think. Nor is thc acetate
Lol
next people will be taking about the weponized cannabis. Gmhc

@Fadedawg couldnt u do a recrystalization in hexanes an dump raw slurry in cold water bath. It would have to be winterized of course

 

[Fadedawg]

We didn't screw around, and bought our acetic anhydride from American Scientific. A liter doesn't raise the same eyebrows a drum does, but it is on the watch list for making illegal drugs. It also doesn't take much, so a liter goes a long way.

Since we've never made illegal drugs, or sold any drug, we have never worried about it and have been left alone, even teaching medical cannabis classes on it and other alchemy.

It is just vinegar with no water, and has to be treated like a strong acid, plus its flammable. Not much of an issue inside a boiling flask with reflux condenser, but it could be without the proper equipment.

A high school chemistry lab graduate would ostensibly have the required safety training, and could easily conduct the process. Making aspirin was a freshman organic chemistry lab assignment for P. Joe, and it isn't rocket science.

Good question, but not my area of expertise, and I actually have a non-disclosure agreement with Joe on his process.

If you will send me an email to [email protected], I'll connect you with Joe and you can pick his keen alleged minds.

thank you for this information, I'm paying attention. to clear things up a bit can you briefly explain why this may have been available or found at a shop that develops film/works with photo store stuff? its canna lore to this guy, its nice to read first hand experience.

first you think it has NOTHING to do with photography, now you see you were wrong on that point aye? You are welcome, I didnt mind at all clearing that up for you.

oh?

see this? "Dilute solutions of acetic acids are also used for their mild acidity. Examples in the household environment include the use in a stop bath during the development of photographic films" =

now, take your beef up with the encyclopedia authors, please stop trolling me with your misinformation. You have lost any credibility those two guys said you had.

Its 19th century photo technology.
Not used in modern photo mats but there was photo supply stores back then.
Its was back when some people develop their own film and had dark rooms at home. Much of it is for black and white photos. More common in the 50s and 60s then started fading out
Also was used to press vinyl records

NOT acetic acid ! We were talking about ACETIC ANHYDRIDE!

Acetic Anhydride is NOT used in developing anything photographic !!!!

YOUR boxed in a corner with truth!
You try and fight your way out with BULL SHIT!

Your grow level is novice at best.

ASS HAT!

This hack goofball Chemphlem is an idiot.

This whole thing began over Acetic Anhydride! It had nothing to do with Acetic Acid or "vinegar".

To use the Anhydride would be way overkill % wise as a stop bath ! Most postings to photography web sites asking where to get it. get answered with you use VINEGAR mixed with water 1:9 to 1:15 strength..The thing is that it was needed for black and white and that depended on what developer you use...If you were using PMK or Dektol, you didn't need a stop bath, only a water tray....I'll venture that those asking are looking to use the anhydride for Shady reasons! Seems like I remember that back in High school, when I had plenty of darkroom time in both graphic arts and straight photography.....the stop bath was a 2% solution..

Anhydride is easy to make. As is sodium acetate, acetic acid, acetamide, acetonitrile,

But the problem with making acetic anhydride is the end purity! With the issue at hand in this thread. Purity is very important to the process and thus, the quality of the end result.
Glacial is only about 28 % and 72% water is not pure enough for this threads proposed use! Thus the need to make (or by) the anhydride.
The water poses new problems of removing it at those concentrations!

I'm only running on High school and first year college chem here.....so if I make a minor error. you know why.

The thing that gets me with the whole process, is that it's a rather complex chemical process. It can go south and be very bad at several places.....The posting of formula's like this....will no doubt one day, hurt some inexperienced drooling noob, who thinks they can duplicate this process in their kitchen! I asked a friend working in chemical Pharmacology about this yesterday. He says he wouldn't try this process at home. (of course he has only spent almost 30 years in labs for the same drug company.)

It's BEYOND obvious that our "friend" phlemy has none!

 

[Fadedawg]

Cellulose Acetate was originally used for movie films, and was made using acetic anhydride. No longer used because of its flammability and instability in storage. It burns like cellulose nitrate, or gun cotton.

They also made replaceable dress shirt collars out of cellulose acetate. Probably not the source of the term hot under the collar, but with great potential.

And speaking of actual experience, an interesting epiphany struck me testing THC Acetate, and that is that it tastes exactly like an acetate and that THC tastes exactly like phenolic plastic, because it is a phenol. It seemed profound at the time.....................

As for making THC Acetate at home, I wouldn't either without the proper training and equipment, neither of which is extensive.

Here are pictures from the original experiment, using the rudimentary equipment that we started with:

 

[The Yorkshireman]

read above my friend. anyhdride is a component of photography,

Anhydride is not a thing, Anhydride is a chemistry term which basically means 'without water'.

An = Without
Hydr (as in hydration) = Water
Anhydride = without water

This is basic suffix and prefix knowledge.


Acetic Acid Anhydride or Acetic Anhydride is Acetic Acid that has had the water removed.

 

[gwpharms]

That sounds like what any educated chemist would say. "I would not suggest people try this at home"
And he is correct to say that. That is a responsible thing to say.

Anhydride is a very nasty substance. It fumes hcl gas in open air.
One has to generate hcl gas to make it.
A dangerous process in many ways.
Fire, explosions, and toxic vapors are to name just a few things that can go wrong
Propper lab ware, adequate ventilation and safety wear such as respirator gloves and apron must be used.
The smell of just glacial acetic acid is enough to put most people down. Anhydride is a distinct and indescribably pundgent aroma. Extremely potent stuff. The smell creeps up on you too. You can hold your face over a beaker of it and say at first you don't smell anything but then bam, your on the floor.
Glacial is 98-99% acetic acid. It frezes at about 16 degrees celcius. Any less and its not glacial. Just vinegar. Otc vinager is 6% acetic acid

He is also correct about purity. Most at home do-it-yourselfer will not be able to get 98% or better purity. Propper equipment procedure and quality grade chemicals are required. Most people dont understand the difference between technical grade solvents they buy at a hardware store and laboratory reagent grade or pharmacuticle grade. Pure solvents are harder for the civilian to aquire and much more expensive. I have the means and know-how to make pure anhydride and I do. I synthesized 90 mol last Tuesday. Do it about every month. Unless somebody is comfortable and experience with other reactions and lab procedures I would not recommend a try this either. They will just waste a lot of time and money and possibly kill themselves or others in the house. All of this stuff mentioned in this thread is no joke. Safety First everyone. It's fun too discuss how to make it and use it but if anyone out there is really in serious need consult your physician.

 

[BobCajun]

Let's just say that acetic anhydride is not used in any modern photography lab, apparently buying a bottle of it does not automatically get you watched by the DEA, and making THC acetate probably isn't worth it anyway. One person here said people seemed to like smoking it, but that's hardly a scientific evaluation. Common sense tells me that it would be pretty much identical to THC except for apparently a faster onset. The person said that it was unstable and reverted back to acetic acid and THC over time. Smoking acetic acid probably wouldn't be great.
