A method for manufacturing 1,4-bis(4-phenoxybenzoylbenzene), 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 including a 1,4-bis(4-phenoxybenzoylbenzene)-Lewis acid complex; contacting the product mixture with a protic solvent, so as to obtain a first phase containing the Lewis acid and a second phase containing 1,4-bis(4-phenoxybenzoylbenzene); subjecting at least the second phase to a solid/liquid separation step by centrifugal filtration, so as to recover solid 1,4-bis(4-phenoxybenzoylbenzene). |
