摘要：

The mechanism of the catalytic ammoximation of cyclohexanone to its oxime with H2O2 over a Ti-silicalite catalysts was suggested on the basis of the analysis of the IR spectra of complexes of ammonia and cyclohexanone adsorbed on the catalyst. It was shown that on the surface of Ti-silicalite cyclohexylimine is formed as precursor which may be then in the following step oxidized to cyclohexanone/oxime by the action of the peroxydic bond on titanium formed after the treatment of Ti-silicalite with H2O2.
