This is what I want to know.

@greenman @skyhighler it is due to purity. I previously posted a paper showing the kinetics of decarboxylation. In that paper they refer to two paths to decarb: naturally occurring acid catalysis, or the high energy path of the keto-enol form.

In the trichome and most extracts, there are naturally occurring acids. These acids cause Decarb to occur through an intermediate interaction between the acid and THCA. This allows decarb to occur at lower energy and is moved forward with things like added light energy or added energy from naturally occurring oxidation.

Once THCA is isolated and other naturally occurring acids are removed, this cannot occur. This leaves the only decarb pathway occurring at much higher energy then the isolated crystals will see at room temp or even exposed to light. The pathway left is the keto-enol form which will take higher energy, i.e added flame, enail, oven, etc.

Thanks for the explanation!

I don't recall a discussion of the Guild's patent application, has anyone found it?

"Our proprietary, patent-pending technology enables us to isolate high levels of THCa to create one of the purest extracts in the world - THCa Powder." https://www.guildextracts.com/products/

any of these? only 3 pages to check

"How Come I Cannot Find Patent Pending Info?

Posted on Sep 30, 2011 by attorney Danton Mak

This is not an unusual case: you see a "patent pending" notice on your competitor's product. Yet when you go to the US Patent Office website, you can find no information about the pending patent under the competitor's company name. How come?

Utility patent applications are published generally 18 months from the earliest priority date claimed in the application. Design patent applications are not published at all. Before publication, the file is kept secret and 3rd parties cannot get information on the application. If you do not find anything under the company name, some of the possiblities could be:

It has been less than 18 months;

The pending application is a design patent application;

You looked in the wrong place (there are 2 separate databases, one for issued patents, and one for published applications);

It is also possible that the applicant requested no-publication (generally the applicant has to forego foreign filing of the application); or

Since all U.S. patent applications are filed in the name(s) of the inventor(s) individually, searching by company name would not produce results if there was no assignment of the application to the company.

One plausible alternative (if you still cannot find the information) would be to order a right to use search. But that is typically quite expensive (thousands of dollars, depending on the technology), and can only be justified for major product lines.

I'm not a patent expert but from my view these techniques have been made public through this site. We have covered the base techniques to produce in it atleast 3 ways. It's also basic chemistry and purification of THCA has been covered in other literature.

They may get the patent through the patent office not seeing anything else but if taken through the courts I don't think it'll hold much weight.

This is how MAPS has protected MDMA from specific use patents.

It's a smart move on Guilds part, however. If they do receive the patent, they could sell it to a company like GW and easy make alot of money very quickly.

Could pangea o weedalcoholic explain it carefully? Ive been reading everything for the last few months, in europe we cant have access to this medicine and i want to make my own, ive noticed that the only way to make it is with column chromatography or acid base extraction, once you have it for obtain the crystals you must use the crystallation technique.... This is very helpful but.... Could you guys explain properly again for the people that are studying the terms with this sustance? I dont know if its better to xtract bho from live resin and try to make a a/b extraction or with normal winterized oil is good to do it

Thanks a lot for this post guys ive been reading you for few months and the account was created for this reason, im an european patient that can have access to this, is not possible in europe, i only want to learn from you mates, this wonderful plant means a lot for me. Thanks for your compression boys

I already got this:

- decarboxylation does not occur in basic conditions but will in acidic conditions
- the base is used to "pull the hydrogen off" of the -COOH of the THC-a. Then once neutralized with an Acid "adding H(+) back to the COO(-), THC-a should precipate out. Sodium bicarb is a weaker base so the idea is it avoids extraction of phenolics but dilute NaOH would work as wellp.

I have an example of a extraction but i dont know the measurements even i dont know if its good:

- Add 50 g grass/liter petroleum ether or benzeme; soak 12 h with occasional shaking; filter and extract petroleum ether 3 times with a solution contaning 5% NaOH and 5% Na2SO3.
- Acidify the aqueous extracts with cold dilute sulfuric acid, acid extract with ether or chloroform which is dried evaporated in a vacuum to yield the cannabidiolic acid.
- THC and cannabidiol remain in the petroleum ether which can be dried and evaporated in a vacuum and the residue added to grass.

Another one:

- Extract three times with charcoal lighter or any lighter or any light aliphatic mix around one mason jarfull or fresh fan leaves or higher quality.
- Prepare solution of 1g NaOH to 250 g H2O.
- Combine the nonpolar and lyewater vigorously, forming sodium thc acid sal.
- Separate layers, non polar can be evapped to yield ok honey oil.
- Acidify aqueous solution with sulfuric or far low pH.
- Add small amount of non polar, shake and remove. Evaporate nonpolar to yield fairly pure thc acid.

Im still learning but with your help i think im going by the correct direction to medicate myself, ive not said that ive making bho for three years and now everything perfectly, since i started to do i wished to know what nowadays im trying to learn but by this time i didn expect that could exist something purer than a good bho.

Thanks a lot for your help and time family. I appreciate it a lot.

In tha last part i wanted to say that no one can have access to it and also i cant get it there, sorry for my english boys
