Title (EN) PROCESS FOR PRODUCING ARYL VINYL SULFONE SOLUTION AND USE THEREOF
(FR) PROCEDE DE PRODUCTION D'UNE SOLUTION DE SULFONE D'ARYLE-VINYLE ET SON UTILISATION
Abstract: front page image
(EN)A process for producing a purified aryl vinyl sulfone solution, characterized by crystallizing an aryl vinyl sulfone from a crude organic solvent solution of the sulfone, removing the solution from the resultant mixture to obtain a wet aryl vinyl sulfone cake, and dissolving the cake in a solvent selected among C¿4-8? ethers, C¿6-10? aromatic hydrocarbons, C¿1-6? halogenated hydrocarbons, C¿3-8? ketones, C¿3-6? esters, and C¿2-6? nitriles.
(FR)L'invention concerne un procédé de production d'une solution purifiée de sulfone d'aryle-vinyle, qui consiste à cristalliser un sulfone d'aryle-vinyle à partir d'une solution dissolvante organique brute de sulfone, à enlever la solution du mélange résultant, de sorte qu'un gâteau humide de sulfone d'aryle-vinyle soit produit, et à dissoudre le gâteau dans un solvant choisi parmi les composés suivants: éthers C¿4-8?, hydrocarbures aromatiques C¿6-10?, hydrocarbures halogénés C¿1-6?, cétones C¿3-8?, esters C¿3-6? et nitriles C¿2-6?.
