A method for manufacturing 1,4-bis(4-phenoxybenzoyl)benzene, including: 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-phenoxybenzoyl)benzene-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-phenoxybenzoyl)benzene. |
