Does anyone know decarb temp for cbd-a and thc-a. It there a way to decarb thca and not Cbda
The difference is too close. The whole thing starts at ~85°C, but I prefer 110°C for 1.5 hours
Is the a chemical way to selectively do it
You can direct the reaction but it won’t be completely selective.
Do you care to explain how
there is no “decarb temperature” period.
at any given temp (except absolute zero), some of the molecules will have enough energy to exceed the activation energy for decarb. leave your weed in the barn for a year, and it will be mostly decarbed. or heat it to 120C for 30min…
what are you trying to achieve?
THC is slightly easier to decarb, but there are no conditions I know of that will decarb one and not the other. best you can do is affect the ratio. given all the variables, you’ll need to try it and see (which requires a way to evaluate the results).
do you have the required analytical equipment to follow your partial decarb? Without it you’re just going to be flailing around in the dark.
one could certainly propose an enzymatic route…but that’s not really R&D work suited for home use.
or maybe crystallize the CBDA, filter from mother liquor, then decarb?
Yes I have analytical what about aluminum oxide
Out of curiosity- What’s your reasoning for wanting one and not the other?
Can’t see any reason for it to be selective…
A polymer such as sixth wave is using in their affinity resin might offer said selectivity. Or you could separate theN decarb.
This just sounds like someone trying to do some thc remediation
I guess. Although some readings of the rules suggest it’s actually only the THC that you need to keep below 0.3%
If you decarb the thca, it counts against you. So selectively decarbing THCA would be taking a “compliant” product to “non-compliant”
If you did have a different decarb rate you could pull the acid compound out with a base though. Would be quick and easy. Might be able to do that with a finely tuned decarb?
Not going to claim it’s impossible.
Only that it looks non-trivial.
I can see it being achieved enzymatically…given time to evolve an appropriate enzyme. As enzymes are merely well shaped catalysts, my assumption would be that a non-biologically sourced catalyst could also be engineered.
Wich direction compounds come to mind ?
