PROCÉDÉ DE FABRICATION DE 1,4-BIS (4-PHÉNOXYBENZOYLE BENZÈNE) À UNE TEMPÉRATURE ÉLEVÉE

摘要

A method for manufacturing 1,4-bis(4-phenoxybenzoyl)benzene, comprising:- providing a solvent, a Lewis acid, a first reactant and a second reactant,wherein the first reactant and the second reactant are respectively terephthaloyl chloride and diphenyl ether, or reversely;- mixing the first reactant in the solvent to make a starting mixture; and,- adding the second reactant to the starting mixture;wherein the Lewis acid is mixed, at least partly, to the starting mixture before adding the second reactant to the starting mixture, and/or wherein the Lewis acid is mixed, at least partly, with the second reactant and added together to the starting mixture, andwherein the temperature of the starting mixture is greater than 5°C during at least part of the step of adding the second reactant to the starting mixture;so as to obtain a product mixture comprising a 1,4-bis(4-phenoxybenzoyl)benzene-Lewis acid complex.
