PREPARATION OF ISOMORPHIC CRYSTALS OF 2*44BIS*2**ACETOXY BENZAMIDO* BE NZOIC ACID

摘要

PURPOSE:2,4-Bis(2'-acetoxybenzamido) benzoic acid (alpha-type) is recrystallized from a solvent of formula R-CN to give an isomorphic crystals (beta-type) of said acid that are more crystals (beta-type) of said acid that are more readily absorbed in living bodies.
