CBD Crystallization

(1/1)

kuddar:
Hello, has anybody carried out the crystallization of CBD successfully? I've received an ethanol extract and now I would like to receive pure CBD in crystal form. I've read about dissolving extract in pentane and freezing. The crystallization should take place spontaneously. But something is wrong with me. Does anybody know a correct order of steps and details of process? For example: mass proportions for extract and solvent (pentane), time and temperature of freezing, etc.
