摘要 考察了N-羟基-N-苯基苯甲酰胺的钴、锰和铜配合物在对氯甲苯液相氧化生成对氯苯甲酸反应中的催化性能。考察了反应温度、催化剂浓度、中心金属离子、以及助催化剂对催化氧化反应的影响,发现以钴配合物为催化剂,反应温度为140℃,催化剂浓度为1.0×10-3 mol·L-1为最佳反应条件。添加NaBr和四甘醇能促进对氯甲苯的氧化。催化剂的使用寿命为72 h,催化效率为2500g对氯苯甲酸/1g钴催化剂。 Cobalt(II),manganese(II) and copper(II) complexes with N-hydroxyl-N-phenyl-benzoic amide was used as catalyst in 4-chloro-toluene oxidation for preparation of 4-chloro-benzoic acid.The influences of reaction temperature,catalyst concentration,adding auxiliary and different metal ion on catalytic oxidation were investigated.When cobalt complex was used as catalyst,the best reaction temperature was 140℃ and the best concentration of catalyst was 1 × 10-3 mol ·L-1.Adding NaBr and tetraethylene glycol could improve the conversion of 4-chloro-toluene in the reaction.The life of catalyst was 72 h and the catalytic efficiency of cobalt complex was 2.5 Kg product/1 g catalyst.
