| Abstract: | Ammoximation of cyclohexanone in the presence of a titanium silicalite (TS 1) catalyst was studied. The result showed that the cyclohexanone conversion increased with the increase of the content of catalyst when pure water was used as solvent, and the high content of H 2O 2 would be propitious to the cyclohexanone conversion but make against the selectivity of oxime,and increasing the amount of NH 3 could increase the selectivity of oxime with higher content of H 2O 2.When m(catalyst)/n(cyclohexanone)=18g∶1mol,H 2O 2∶cyclohexanon=2.5∶1(mole),NH 3∶H 2O 2=2.5∶1(mole),NH 3 interval addition,temperature 73℃,reaction 5h, the yield of cyclohexanone oxime could reach 96%. |
