METHOD OF SYNTHESIS OF POLYOXYALKYLENE GLYCOL ESTERS Russian patent published in 2002 - IPC

FIELD: organic chemistry, chemical technology. SUBSTANCE: invention relates to the improved method of synthesis of polyoxyalkylene glycol esters, in part, oxyalkylated higher saturated alcohols, alkylphenols, glycols, amines and carboxylic acids, highly effective nonionogenic surface-active substances. These compounds are used widely in different branches of industry and in homes. Polyoxyalkylene glycol esters are synthesized by interaction of alkylene oxides with compounds comprising a mobile hydrogen atom under increased pressure and temperature in the presence of alkaline metal alcoholates in reactor unit including one or some displacement reactors. Devices where reaction volume is placed between two surfaces of heat-exchanger are used. Method provides to use different raw species. EFFECT: improved method of synthesis, increased specific output of reactor unit. 9 cl, 5 dwg, 7 ex
