近年来 ,有机氧化合成领域出现了一些新的氧化方法 :在分子筛催化剂作用下 ,以N2 O作羟基化剂 ,直接将苯气相氧化为苯酚 ;钛硅分子筛催化剂一步催化丙烯与H2 O2 反应生成环氧丙烷 ;以分子氧为氧源 ,在水 /有机两相体系 ,催化四氢萘的自动氧化 ,α -四氢萘酮的选择性为 6 8% ;利用水在阳极产生的活性氧直接使丙烯环氧化生成环氧丙烷 ,实现了以电子代替H2 O2 催化丙烯环氧化。新方法与使用有毒或腐蚀性的反应物和产生大量废弃物的传统工艺相比较 ,更加接近绿色化学所提出的目标。对催化体系和过程的深入研究 ,新的高效催化剂的开发 ,将推动绿色化学进一步发展 In recent years, there are some new oxidation methods in the field of organic oxidation synthesis: using N2O as hydroxylation agent under the action of molecular sieve catalyst to directly convert benzene to phenol by gas phase; reacting titanium oxide and H2O2 to form ring by one-step reaction of titanium-silicon molecular sieve catalyst Oxygen propane; molecular oxygen as oxygen source, in the water / organic two-phase system, catalytic tetralin auto-oxidation, α-tetralone selectivity of 68%; the use of water at the anode to produce active oxygen directly Epoxidation of propylene to propylene oxide, the realization of the electronic replacement of H2 O2 propylene epoxidation. The new approach is closer to the goals set by Green Chemistry than the use of toxic or corrosive reactants and traditional processes that generate large amounts of waste. In-depth study of the catalytic system and process, the development of new and efficient catalysts will promote the further development of green chemistry
