摘要
A method for manufacturing 1,4-bis(4-phenoxybenzoyl)benzene, including: providing terephthaloyl chloride, diphenyl ether, a solvent and a Lewis acid, wherein the terephthaloyl chloride is of a purity grade such that, 10 minutes after introducing it at a reference concentration of 6.5 wt. % into said solvent, at a temperature of 20° C., a solution is obtained having a turbidity of less than 500 NTU; mixing the terephthaloyl chloride, the diphenyl ether and the solvent so as to make a reactant mixture; adding the Lewis acid to the reactant mixture so as to effect the reaction of the terephthaloyl chloride with the diphenyl ether; recovering a product mixture comprising a 1,4-bis(4-phenoxybenzoyl)benzene-Lewis acid complex.
