The idea is to make a derivative salt out of thca that can be crystallized easily to nearly pure then cleave the addition to make pure thca or thc
" In general the purity of this crude crystalline ester will be well over 90% pure. About 70 to 80% of the initially assayed cannabinoid can be obtained in the first crop of crystals. Purification of up to greater than 99% can typically be achieved by one recrystallization, preferable from an alcohol, with minimal
losses in yield. (All percentages given herein are weight percentages unless otherwise noted.) The resulting cannabinoid esters are highly crystalline and stable at room temperature. They can be stored indefinitely at room temperature under air. The cannabinoid esters can then be hydrolyzed to recover the pure cannabinoid by base hydrolysis "
y exactly they did this? cause science thats why
i know its not something thats gonna be done large scale anytime soon but its an interesting read
