The solubilities of alpha-, beta-, and gamma-glycine in aqueous solutions containing methanol, ethanol, 2-propanol, or acetone were measured at 3 10 K. The solubility of all the polymorphs dropped rapidly as a function of the concentration of antisolvent. The solubility of the glycine polymorphs in water-anti solvent mixtures was, in decreasing order: methanol > ethanol > 2-propanol > acetone. The solubility of alpha-glycine was slightly higher than that of gamma-glycine, but the solubility of beta-glycine was significantly higher by up to 17 %. The induction time for the recrystallization of beta- to alpha-glycine in those water-anti solvent mixtures was, in decreasing order: methanol > ethanol > acetone > 2-propanol. This signifies that the selection of an antisolvent for preparation of beta-glycine can have an important effect on the product.
