METHOD OF SYNTHESIS OF CHLOROMETHYL GROUP-CONTAINING ORGANOCHLORINE COMPOUNDS OR THEIR QUATERNARY AMMONIUM SALTS Russian patent published in 2000 - IPC

Abstract RU 2150455 C1

FIELD: organic chemistry, chemical technology. SUBSTANCE: invention relates to synthesis of chloromethyl group-containing organochloride compounds or their ammonium salts of the general formula: H(C6H4CH2)nCl where n = 2-4 that are used extensively as surface-active substances. Process involves the condensation of benzyl chloride at increased temperature. Condensation is carried out in the presence of zinc chloride aqueous solution, hydrogen chloride or hydrochloric acid at simultaneous bubbling with inert gas at the preferable rate 1 m3/h/1 t of reacting substances. Components are taken in the mass ratio = = 1:(0.02-0.05):(0.01-0.025):(0.0001-0.001). EFFECT: decreased time of induction reaction, improved quality of synthesized chloromethyl compounds, simplified technology of process. 1 tbl, 10 ex
