METHOD OF SYNTHESIS OF MONOATOMIC ALIPHATIC ALCOHOLS C-C Russian patent published in 1995 - IPC

FIELD: chemical technology. SUBSTANCE: acetic acid and alcohol at ratio 1:(1.03-1.1) were fed to reactor containing stationary layer of ion-exchange resin КУ-2 or КУ-2 ФПП or ПФКС-1 in H⁺--form at 95 C, at catalyst output 0.9-1.17 g/g x h). Reaction mass is removed into marginal vat of fractionating column from the upper of which heteroazeotropic mixture ester-water is taken off. Composition of reaction mass into the vat, wt.-%: alcohol 0.5-3.0; ester 30-35; water 8-12, and acetic acid up to 100%. Time of reaction mass staying into vat column is 10-11 h. EFFECT: improved method of synthesis. 7 tbl, 2 dwg
