DISSOCIATION OF A 1,4-BIS(4-PHENOXYBENZOYL)BENZENE-LEWIS ACID-COMPLEX IN AN AQUEOUS SOLUTION

摘要

The invention relates to a method for manufacturing 1,4-bis(4-phenoxybenzoylbenzene), comprising: - reacting terephthaloyl chloride with diphenyl ether in a reaction solvent and in the presence of a Lewis acid, so as to obtain a product mixture comprising a 1,4-bis(4-phenoxybenzoylbenzene)-Lewis acid complex; - putting the product mixture in contact with an aqueous solution, so as to obtain an aqueous phase containing the Lewis acid and an organic phase containing 1,4-bis(4-phenoxybenzoylbenzene).
