ABSTRACT:
Primary saturated aliphatic and alicyclic amines are oxidized by elemented oxygen to oximes, especially cyclohexylamine to cyclohexanone oxime, in vapor phase using silica gel catalyst; preferably using concentrations by volume such as 1% to 5% of amine and 5% to 30% of oxygen, and using temperatures between about 120.degree. C. and 250.degree. C. at atmospheric pressure.
