Abstract: A method for producing cyclohexanone oxime, comprising the steps of: (1) subjecting cyclohexene or cyclohexanol to amination to obtain cyclohexylamine, and (2) subjecting the obtained cyclohexylamine to partial oxidation to obtain cyclohexanone oxime.
Abstract: Oximes are prepared by reacting carbonyl compounds, hydrogen peroxide and ammonia in the presence of a catalyst system comprising a catalyst comprising titanium, silicon and oxygen and a cocatalyst comprising an acidic solid comprising an organic or inorganic support material, where either the support material itself has Lewis-acid or Brönsted acid properties, or Lewis-acid or Brönsted-acid functional groups are applied to the support material.
