METHOD OF SYNTHESIS OF ALKYL-TERT-ALKYL ESTERS Russian patent published in 1996 - IPC

Abstract RU 2064919 C1

FIELD: organic chemistry, chemical technology. SUBSTANCE: olefins were subjected for interaction with alcohols in the presence of solid sulfaonite catalyst at increased temperature and pressure in unit with separated zones of rectification and some reaction zones in which catalyst is placed that is put into liquid, completely or partially. Total vapor current is passed from every low-arranged rectification zone to up-arranged rectification zone by hollow vertical channel and from 5 to 70% of total vapor current - through catalyst layer. EFFECT: improved method of synthesis. 9 ex, 3 dwg, 3 cl
