Abstract
FIELD: chemical technology. SUBSTANCE: product: acetamidine chlorohydrate which is used for vitamin ACH production. Synthesis of acetamidine chlorohydrate is carried out by treatment with acetonitrile, ethanol and HCl. Firstly the saturation is carried out separately, and acetonitrile is saturated at 5-9 C, and then it is mixed with saturated HCl with alcohol at 8-12 C. Then crystallization is carried out, and acetiminoester is prepared which is amidated with ammonium spirituous solution, and the end acetamidine chlorohydrate is isolated. Method ensures to increase the yield of the end product by 16.8% to shorten process duration by 20% and to decrease alcohol load in the process of amidination by 45% EFFECT: increased yield, shortened process duration. 1 tbl
