Stability: Δ9-THCA is very unstable, decomposing rapidly in the presence of oxygen, light and acids. It is stable for 3 months at -20°C, 2 weeks at 5°C, and 4 days at room temperature (Zoller et. al. 2000). Δ9-THCA powder appears to be more stable but stability is indeterminate at this time.
Storage: -20°C
Shipping: On ice (5°C)
Handling: Avoid exposure to oxygen, acids and direct sunlight
From my research thca has a slight color to it. And it degrades easily into d8 in the presence of acid .so my question is… with these crc medias being acidic one could theorize that your extracted solution will be acidic. What is happening when you let your diamonds crash out in a acid solution? Is the thca degrading over time? Are people really crashing d8 With crc? Anyone have test results they would like to share?

Seems once it rocks up it becomes more stable but in a solution it is very unstable
I have stable crystals from when we first started doing the crc stuff. What you want to watch out for is doing crc pre distillation, cbd among other things can be partially isomerized like this.If you would like to avoid this I would suggest a pressure filtration of the first or second pass distillate dissolved in a np solvent before final evaporation.
Are we talking D8-THCa or D8-THC? I’m not sure if I’ve ever seen THCa>D8-THC but I don’t even know if I’ve seen D8-THCa on a lab result so honestly I’ve got nothing to go off of here.
You can grow diamonds from CRC’d material no problem. No worries about isomerization. When it comes to cannabinoids, you really need both an acidic environment and significant heat to be able to get over the energy barrier to create cannabinoid isomers (d8).
I have used CRC’d extract as starting material for SPD before, all I did was disolve it into hexane and do a pH 4 saline wash, followed by a pH 10 saline wash, followed by a pH 7 saline wash to neutralize. No issues during distillation, and resulted in 96%d9 THC second pass distillate.
Good to note though, if you are simply decarbing a CRC’d extract on a hot plate (our process involves separating the terpene and cannabinoid fractions, so we decarb the THCA portion on a hot plate) you do not need to worry about isomerization. It does seem to take longer to decarb, but that may have been because of the crystal structure of the starting extract.
I’ve had a diamond sitting room temp for several weeks and have even left my house and turned the ac all the way up (warm) when I was gone for several days at a time. And it’s still a solid.
if kept in right conditions I may be filled but it may have a very long shelf life w the terpenes going first. enough terps and enough heat and it may dissolve some. but that’s the only way
I wouldn’t be too worried about it. Acids cannot dissociate into alkanes so the interaction of the acids with the THCa will be limited to whatever bit of solution is physically surrounding the particles of leftover media. If that is the case then the clays ability to convert thca into d8 will only be limited to the amount of acidic medias left in your extract, which weight wise compared to the rest of the solution is going to be negligible.
