The invention relates to a method for manufacturing 1,4-bis(4-phenoxybenzoylbenzene), comprising: 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-phenoxybenzoylbenzene)-Lewis acid complex; putting the product mixturein contact 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); heating at least the second phase up to a maximum temperature, followed by cooling the second phase down to a separation temperature; subjecting at least the second phase to a solid / liquid separation step at the separation temperature, so as to recover solid 1,4-bis(4-phenoxybenzoylbenzene).
本发明涉及一种制备1,4-双(4-苯氧基苯甲酰基)苯的方法,包括以下步骤:在反应溶剂和Lewis酸的存在下,将对苯二甲酰氯与二苯醚反应,以获得包含1,4-双(4-苯氧基苯甲酰基)苯-Lewis酸复合物的产物混合物;将产物混合物与质子溶剂接触,以获得含有Lewis酸的第一相和含有1,4-双(4-苯氧基苯甲酰基)苯的第二相;将至少第二相加热至最高温度,然后将第二相冷却至分离温度;将至少第二相在分离温度下进行固体/液体分离步骤,以回收固体1,4-双(4-苯氧基苯甲酰基)苯。
