Title (EN) CONTINUOUS PROCESS FOR THE ESTERIFICATION OF AN ALPHA,BETA-UNSATURATED CARBOXYLIC ACID AND AN ALCOHOL
(FR) PROCÉDÉ EN CONTINU POUR L’ESTÉRIFICATION D'UN ACIDE CARBOXYLIQUE ALPHA,BÊTA-INSATURÉ ET D'UN ALCOOL
Abstract:
(EN) A continuous process for the esterification of an alpha, beta-unsaturated carboxylic acid and a mono-alcohol having 5 or more carbon atoms in a reactive distillation chamber, comprising the steps of a) feeding a first feed stream comprising the alpha, beta-unsaturated carboxylic acid to the lower half of the reactive distillation chamber and feeding a second feed stream comprising the mono-alcohol having 5 or more carbon atoms to the upper half of the reactive distillation chamber so as to cause a countercurrent flow of alcohol and carboxylic acid in the reactive distillation chamber, wherein the feed molar ratio of mono- alcohol having 5 or more carbon atoms to acid groups of the alpha, beta- unsaturated carboxylic acid is in the range of 0.95 to 1.20, b) causing the alpha, beta-unsaturated carboxylic acid and the alcohol to form an ester in the reactive distillation chamber by heating, wherein the temperature in the bottom part of the reactive distillation chamber is in the range of 130 to 250 °C, and wherein the pressure in the reactive distillation chamber is below atmospheric pressure, c) removing reaction water by distillation, and optionally separating organic material from the distillate, and recycling any separated organic material to the reactive distillation chamber, and d) removing the formed ester from the bottom of the reactive distillation chamber.
(FR) L'invention porte sur un procédé en continu pour l'estérification d'un acide carboxylique alpha,bêta-insaturé et d'un monoalcool ayant 5 ou plus de 5 atomes de carbone dans une chambre de distillation réactive, ledit procédé comprenant les étapes consistant a) à introduire un premier courant de charge d'alimentation comportant l'acide carboxylique alpha, bêta-insaturé dans la moitié inférieure de la chambre de distillation réactive et à introduire un second courant de charge d'alimentation comportant le mono-alcool ayant 5 ou plus de 5 atomes de carbone dans la moitié supérieure de la chambre de distillation réactive afin de provoquer un écoulement à contre-courant d'alcool et d'acide carboxylique dans la chambre de distillation réactive, le rapport molaire d'introduction du mono-alcool ayant 5 ou plus de 5 atomes de carbone aux groupes acides de l'acide carboxylique alpha, bêta-insaturé étant dans la plage de 0,95 à 1,20, b) à amener l'acide carboxylique alpha, bêta-insaturé et l'alcool à former un ester dans la chambre de distillation réactive par chauffage, la température dans la partie de fond de la chambre de distillation réactive étant dans la plage de 130 à 250 °C et la pression dans la chambre de distillation réactive étant au-dessous de la pression atmosphérique, c) à enlever l'eau de réaction par distillation et éventuellement à séparer la matière organique du distillat et à recycler toute matière organique séparée dans la chambre de distillation réactive, et d) à soutirer l'ester formé du fond de la chambre de distillation réactive.
