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.- Esterification process of aliphatic carboxylic acids. This process consists of reacting an aliphatic carboxylic acid containing 1 to 6 carbon atoms with a methyl-tertioalkyl ether in which the tertiary alkyl group contains 4 to 7 carbon atoms in the presence of an acid catalyst selected from the group formed by sulfuric acid, an aliphatic or aromatic sulfonic acid, a perfluoroalkyl sulfonic acid, a perfluoroalkyl phosphonic acid, and a heteropolyacid represented by the formula: Hn Aa Dc Oy. XH2 O formula in which A represents phosphorus, boron, silicon, germanium, tin, arsenic, antimony, uranium, manganese, rhenium, copper, nickel, cobalt, iron, cerium, thorium, chromium and D represents molybdenum, tungsten, vanadium. Usable for obtaining, with excellent selectivities, methyl esters and tertioalkylolefins.
