| 摘 要： | 钛硅分子筛/H2O2 体系催化酮氨肟化反应合成肟的过程中, 产物肟的反应行为直接影响氨肟化过程的反应效率和操作稳定性. 在 Ti-MWW/H2O2 体系催化丁酮氨肟化反应中研究了产物丁酮肟的反应行为, 发现 Ti-MWW 和 H2O2 的共同作用促使丁酮肟发生水解, 生成丁酮和氮氧化物, 使得反应体系从碱性变成了酸性. TS-1/H2O2 体系及产物环己酮肟均存在类似的现象.

| Abstract: | In the preparation process of oxime over the titanosilicate/H2O2 system,the reaction performance of oxime influenced the effi-ciency and stability of the process directly.The reaction behavior of methyl ethyl ketone oxime produced from ammoximation of methyl ethyl ketone catalyzed by the Ti-MWW/H2O2 system was studied.The Ti-MWW and H2O2 together resulted in the hydrolysis of methyl ethyl ketone oxime to methyl ethyl ketone,NOx,etc.Thus,the system was from alkalescence to acidity.The same phenomena also exi... |
