中文摘要：
在常压、无溶剂条件下,以氧气为氧化剂,研究了金属卟啉及金属卟啉-过渡金属盐复合催化体系对氧化对硝基乙苯制备对硝基苯乙酮的催化作用.发现所有金属卟啉及金属卟啉-过渡金属盐复合催化剂对上述反应均具有催化活性,且催化效果有明显的差别.金属卟啉与过渡金属盐的复合催化体系比单独的金属卟啉催化体系具有更好的效果,且具有明显的协同作用.其中氯化四-（对-甲氧基苯基）锰卟啉-硬脂酸钴复合催化剂的效果最好,可使反应的引发温度从无催化剂（空白）的190℃降低到155℃,对硝基乙苯的转化率从11.3%提高到61.5%,对硝基苯乙酮的选择性从52.5%提高到88.9%,相应的收率也从5.9%提高到54.7%.
英文摘要：
The catalytic performances of metalloporphyrins and compounding catalytic systems in the aerobic oxidation of 4-nitroethylbenzene to 4-nitroacetophenone is comprehensively investigated with a solvent-free system at atmospheric pressure.It is found that all of the metalloporphyrins or compounding catalytic systems have catalytic performances,and the catalytic performances of different metalloporphyrins or compounding catalytic systems are obviously diverse.Meanwhile,the cooperation of metalloporphyrins and transition metallic salts in the above reactions is acquired because the catalytic effects of the compounding catalytic systems are better than the metalloporphyrins as single catalyst.Compared the oxidation of 4-nitroethylbenzene catalyzed by T（p-OCH3）PPMnCl-cobalt stearate as the best compounding catalytic system with the reaction without catalysts（blank reaction）,the initiation temperature decreases from 190 ℃ to 155 ℃,while the conversion of 4-nitroethylbenze increases from 11.3% to 61.5%,the selectivity for 4-nitroacetophenone increases from 52.5% to 88.9%,and the yield of 4-nitroacetophenone increases from 5.9% to 54.7%.
