Abstract
- Procédé d'estérification d'acides carboxyliques aliphatiques. Ce procédé consiste à faire réagir un acide carboxylique aliphatique contenant de 1 à 6 atomes de carbone avec un méthyl-tertioalkyl-éther dans lequel le groupe alkyl tertiaire contient de 4 à 7 atomes de carbone en présence d'un catalyseur acide choisi dans le groupe formé par l'acide sulfurique, un acide sulfonique aliphatique ou aromatique, un acide perfluoroalkyl sulfonique, un acide perfluoroalkyl phosphonique, et un hétéropolyacide représenté par la formule : Hn Aa Dc Oy . XH2 O formule dans laquelle A représente le phosphore, le bore, le silicium, le germanium, l'étain, l'arsenic, l'antimoine, l'uranium, le manganèse, le rhénium, le cuivre, le nickel, le cobalt, le fer, le cérium, le thorium, le chrome et D représente le molybdène, le tungstène, le vanadium. Utilisable pour l'obtention, avec d'excellentes sélectivités, d'esters méthyliques et de tertioalkyl-oléfines.
