Abstract

L'invention concerne la préparation d'esters utilisables comme plastifiants. Elle a trait plus particulièrement à la purification des ces esters obtenus par estérification en 1 en présence d'au moins un titanate de tétraalkyle. Après la réaction d'estérification, successivement : - dans une première étape on refroidit le milieu réactionnel à une température comprise entre 50 degrés C et 150 degrés C environ sous pression atmosphérique, - dans une deuxième étape en 9 on ajoute au milieu réactionnel une quantité d'eau comprise entre environ 0,05% et environ 5% en poids par rapport au poids d'ester, - dans une troisième étape en 12 on sépare par filtration le catalyseur hydrolysé du milieu réactionnel, - dans une quatrième étape en 17, on soumet le mélange restant à un entraînement à la vapeur d'eau sous vide pour séparer l'alcool excédentaire et on sèche l'ester obtenu.
