| 摘 要： | 采用钼的杂多酸为催化剂,三辛基甲基氯化铵为相转移剂,以双氧水为氧化剂在两相反应中催化氧化苯乙烯,生成中间产物环氧苯乙烷;在催化剂催化下,环氧苯乙烷开环,生成苯甲醛和苯基乙二醇等产物,单程转化率达到28.44%(基于苯乙烯),在55℃,双氧水浓度为12%时,反应生成苯甲醛的选择性为100%,通过对平衡反应的研究,得到了不同参量对3种产物选择性的影响,工业上可以通过精馏分离,得到纯净的3种有机物。

| Abstract: | Oxidation of styrene with aqueous H2O2 converted to styrene oxide by using synergism of Mo-based heteropoly acids and trioctylmethylammonium chloride in a biphasic system,the conversion is 28.44%(based on styrene).Following with the reaction,benzaldehyde and phenyl glycol could be obtained from the fine chemical intermediate,especially at 55 ℃ the selectivity for benzaldehyde is 100% by using 12% H2O2.By studying the balanced reaction,it was found that effects of various parameters for three production is obvious.The pure productions can be obtained by rectify in industry. |
