Abstract

L'invention a trait au domaine de la fabrication d'esters de glycol. Le procédé est essentiellement caractérisé en ce qu'on fait réagir une oléfine, un acide carboxylique et de l'oxygène, en présence d'un catalyseur, dans un réacteur allongé verticalement il muni d'une branche de recirculation 18 entre la partie supérieure et la partie inférieure, en conférant au milieu réactionnel une vitesse superficielle verticale et dirigée vers le haut, d'au moins 0,015 m/sec. Application à la fabrication d'esters de glycol, notamment d'éthylène-glycol et de propylène-glycol.The invention relates to the field of the manufacture of glycol esters. The process is essentially characterized in that an olefin, a carboxylic acid and oxygen are reacted, in the presence of a catalyst, in a vertically elongated reactor equipped with a recirculation branch 18 between the upper part and the lower part, by giving the reaction medium a vertical surface speed directed upward, of at least 0.015 m / sec. Application to the manufacture of glycol esters, in particular of ethylene glycol and of propylene glycol.
