Abstract: A method for manufacturing 1,4-bis(4-phenoxybenzoyl)benzene, including: reacting terephthaloyl chloride with diphenyl ether in the presence of a Lewis acid, so as to obtain a product mixture including 1,4-bis(4-phenoxybenzoyl)benzene-Lewis acid complex, wherein the 1,4-bis(4-phenoxybenzoyl)benzene-Lewis acid complex is, at least partly, in the form of a precipitate; carrying out a solid/liquid separation of the product mixture to obtain a cake comprising the 1,4-bis(4-phenoxybenzoyl)benzene-Lewis acid complex precipitate; putting the cake in contact with a decomplexing solvent, wherein the decomplexing solvent is a protic solvent, so as to dissociate the 1,4-bis(4-phenoxybenzoyl)benzene-Lewis acid complex into 1,4-bis(4-phenoxybenzoyl)benzene; and, recovering the 1,4-bis(4-phenoxybenzoyl)benzene. Also, a method for manufacturing a polyaryletherketone polymer starting from 1,4-bis(4-phenoxybenzoyl)benzene manufactured by the above method.
