PROCESS FOR THE MANUFACTURE OF 1,4-BIS(4-PHENOXYBENZOYL)BENZENE WITH CERTAIN METAL-CONTAINING CATALYSTS |
摘要 |
1,4-bis(4-phenoxybenzoyl)benzene is made in a homogeneous or heterogeneous system by a reaction of diphenyl ether with 1,4-benzenedicarbonyl chloride at 220-258 DEG C in the presence of certain iron, gallium, and indium compounds in catalytic amounts. The mole ratio of diphenyl ether to 1,4-dicarbonyl chloride is 5:1 to 25:1 and the mole ratio of 1,4-benzenedicarbonyl chloride to the catalyst is 1000:1 to 10:1. |
