Continuous preparation of acetic acid esters

摘要: A process for the preparation of acetic acid esters CH 3 --CO--O--R 1 (I, R =an organic radical other than methyl and ethyl) by alkali-catalyzed trans-esterification an ester 2 (II, =methyl or with alcohol --OH (III), accompanied elimination (IV), wherein (a) reaction is carried out in middle section K M a distillation column K, III being fed as liquid into upper zone II lower , (b) alkaline catalyst introduced part U (c) IV, mixture IV II, taken off top column, (d) obtained from (unless alone obtained) separated stripper S azeotrope latter recycled to (e) I vapor L (f) either removed, conventional manner.
