Dissociation of 1,4-bis (4-phenylphenyl) benzene Lewis acid complex in 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).
