Title (EN) METHOD FOR PREPARING OXYSULPHIDE AND FLUORINATED DERIVATIVES BY SULPHINATION
(FR) PROCEDE DE PREPARATION DE DERIVES OXYSULFURES ET FLUORES PAR SULFINATION
Abstract: front page image
(EN)The invention concerns a method for preparing an oxysulphide and fluorinated derivative, said method comprising the reacting, in the presence of an organic solvent, of: i) at least one compound of formula Ea-COOR (I), in which Ea represents the fluorine atom or a group having 1 to 10 carbon atoms chosen from fluoroalkyls, perfluoroalkyls and fluoroalkenyls and R represents hydrogen, a monovalent cation or an alkyl group, and ii) a sulphur oxide, said method being such that the initial molar ratio (sulphur oxide/compound of formula (I)) is less than 0.4 and the concentration of sulphur oxide dissolved in the reaction medium is kept constant for the entire duration of the reaction to a value of between 0.2% and 3% by weight by means of continually adding said sulphur oxide to the reaction medium.
(FR)On décrit un procédé de préparation d'un dérivé oxysulfuré et fluoré comprenant la mise en réaction, en présence d'un solvant organique : i) d'au moins un composé de formule Ea-COOR (I), où Ea représente l'atome de fluor ou un groupe ayant de 1 à 10 atomes de carbone choisi parmi les fluoroalkyles, les perfluoroalkyles et les fluoroalkényles et R représente l'hydrogène, un cation monovalent ou un groupe alkyle, et ii) d'un oxyde de soufre, ledit procédé étant tel que le rapport molaire initial (oxyde de soufre/composé de formule (I)) est inférieur à 0,4 et la concentration en oxyde de soufre dissous dans le milieu réactionnel est maintenue constante durant toute la durée de la réaction à une valeur comprise entre 0,2% et 3% poids par un ajout continu dudit oxyde de soufre au milieu réactionnel.
