摘要：

The ammoximation of cyclohexanone to cyclohexanone oxime over the titanium silicalite TS-1 with NH3 and H2O2 is reported. The ammoximation takes place at conversions exceeding 90% with selectivities greater than 99%. The influence of various catalyst and process parameters on the oximation reaction is reported. By-products from condensation reactions become significant at low concentrations of H2O2 and NH3. Possible mechanisms for the formation of the oxime and by-products are reported. © 1991.
