摘要
The invention relates to amethod for manufacturing 1,4-bis(4-phenoxybenzoylbenzene), comprising: providing a reactant mixture comprising terephthaloyl chloride, diphenyl ether and a Lewis acid in a solvent; reacting terephthaloyl chloride with diphenyl ether, so as to obtain a product mixture comprising a 1,4-bis(4-phenoxybenzoylbenzene)- Lewis acid complex; wherein the 1,4-bis(4-phenoxybenzoylbenzene)-Lewis acid complex is dissolved in the solvent at a 1,4-bis(4-phenoxybenzoylbenzene) weight concentration in the solvent which is higher than the saturation limit of the 1,4-bis(4-phenoxybenzoylbenzene)-Lewis acid complex during at least part of the step of reacting terephthaloyl chloride with diphenyl ether.
