Abstract
FIELD: organic chemistry. SUBSTANCE: desired product is prepared of monoethanol amine and HSO. Dehydration and isolation 2-aminoethyl sulfonic acid are carried out at 102-130 C by evaporating water. Thus prepared product is purified by recrystallization, 28-32 % aqueous alcohol being used. The process is followed by treatment with sodium sulfite during boiling in water. Then extraction simultaneously with steaming and absorption of dry HCl are carried out. The former process takes place in the presence of NaCl. Hydrochloric acid is distilled till residual volume is 30-35 % of its initial value. Reaction mass is treated by pouring it into 88-92 % alcohol. Desired product is washed with the same solution. EFFECT: increases yield of desired product, increases main substance content, utilizes waste of the process. 1 dwg
