    摘要: The present disclosure pertains to a process for preparing an oxime in which a carbonyl compound is reacted in the liquid phase with NH3 and H2O2 in the presence of a catalyst to form the corresponding oxime, wherein the catalyst comprises a catalytic component selected from the oxides of metals of group 5 and group 6. The use of a niobia catalyst is particularly preferred. The process according to the disclosure is suitable for the manufacture of numerous oximes, in particular cyclohexanone oxime.
