Title (EN) FLUOROCARBON COMPOUNDS AND PROCESSES FOR PREPARATION THEREOF
(FR) COMPOSES DE FLUOROCARBONES ET LEURS PROCEDES DE PREPARATION
Abstract:
(EN) Fluorinated (poly)sulfates, halosulfonates, halohydrins and epoxides, as well as processes for producing them are disclosed. These compounds have the formulas R2R3FCCHXCHR1(OSO2)nZ, wherein each R2 and R3 is independently fluorine or perfluoroalkyl, R1 is H or -CFR2R3, X is selected from chlorine, bromine and iodine, Z is selected from the group consisting of chlorine, bromine and -OCHR1CHXCFR2R3 and n is an integer from 1 to 6, R2R3CHXCH(OH)CFR2R3, wherein each R2 and R3 is independently fluorine or perfluoroalkyl, and X is chlorine, bromine or iodine, formula (A), wherein each R2 and each R3 is independently fluorine or perfluoroalkyl.
(FR) L'invention concerne des (poly)sulfates, halosulphonates, halohydrines et époxydes, ainsi que leurs procédés de production. Ces composés ont la formule: R2R3FCCHXCHR1(OSO2)nZ, dans laquelle chaque R1 et R3 représentent indépendamment du fluor ou du perfluoroalkyle, R1 représente H ou -CFR2R3, X est choisi parmi le chlore, le brome et l'iode, Z est choisi dans le groupe composé de chlore, de brome et de -OCHR1CHXCFR2R3, et n représente un nombre entier compris entre 1 et 6, la formule R2R3CHXCH(OH)CFR2R3, dans laquelle chaque R2 et R3 représentent indépendamment du fluor ou du perfluoroalkyle, et X représente du chlore, du brome ou de l'iode, la formule (A), dans laquelle R2 et chaque R3 représente indépendamment du fluor ou du perfluoroalkyle.
