Title
(EN) PREPARATION OF ESTERS BY THE STAGED ADDITION OF THE LOWER BOILING POINT COMPONENT OF MIXED ALCOHOLS OR ACIDS
(FR) PREPARATION D'ESTERS PAR ADDITION EN PLUSIEURS FOIS DU COMPOSANT PRESENTANT LE POINT D'EBULLITION LE PLUS BAS D'ALCOOLS OU D'ACIDES MELANGES
Abstract
(EN)
A process for the esterification of acids or anhydride with alcohols or a polyhydroxy compound wherein the heavier or higher boiling point component of the mixed lower boiling point reactant is added to the reaction vessel subsequent to the addition of both the higher boiling point reactant and the lighter or lower boiling point component of the lower boiling point reactant.
(FR)
L'invention concerne un procédé d'estérification d'acides ou d'un anhydride avec des alcools, ou d'un composé polyhydroxy, procédé selon lequel le composant le plus lourd ou présentant le point d'ébullition le plus élevé du réactif mélangé présentant le point d'ébullition le plus bas est ajouté à la cuve de réaction après addition du réactif présentant le point d'ébullition le plus haut et du composant le plus léger ou présentant le point d'ébullition le plus bas du réactif présentant le point d'ébullition le plus bas.
