Abstract

PROCEDE DE REMPLACEMENT D'UN SUBSTITUANT HALOGENE PAR UN HYDROGENE DANS UN ETHER ALIPHATIQUE HALOGENE DE TYPE METHYLE-ETHYLE OU ETHYLE-ETHYLE. LE PROCEDE CONSISTE A FAIRE REAGIR AVEC UN ALCANOL PRIMAIRE OU SECONDAIRE ET UNE BASE MINERALE UN ETHER ALIPHATIQUE HALOGENE DE FORMULE: (CF DESSIN DANS BOPI) OU AU MOINS L'UN DES GROUPES CXCY EST CHOISI PARMI: (CF DESSIN DANS BOPI) ET L'AUTRE GROUPE CXCY PEUT ETRE IDENTIQUE OU PEUT ETRE CHOISI PARMI: (CF DESSIN DANS BOPI) APPLICATION A L'OBTENTION D'ETHERS.PROCESS FOR REPLACING A HALOGENIC SUBSTITUTE BY A HYDROGEN IN A HALOGENATED ALIPHATIC ETHER OF METHYL-ETHYL OR ETHYL-ETHYL TYPE. THE PROCESS CONSISTS OF REACTING WITH A PRIMARY OR SECONDARY ALCANOL AND A MINERAL BASE AN ALIPHATIC HALOGEN ETHER OF FORMULA: (CF DESIGN IN BOPI) OR AT LEAST ONE OF THE CXCY GROUPS IS CHOSEN FROM: (CF DESIGN IN BOPI) AND L ANOTHER CXCY GROUP MAY BE IDENTICAL OR MAY BE CHOSEN FROM: (CF DRAWING IN BOPI) APPLICATION TO OBTAINING ETHERS.
