Abstract
Oximes can be converted to the corresponding amides by contacting the oximes with a non-zeolitic molecular sieve, which has in its calcined form an adsorption of isobutane of at least about 2 percent by weight of the non-zeolitic molecular sieve at a partial pressure of 500 torr and a temperature of 20.degree. C. The process is especially useful for the conversion of cyclohexanone oxime to caprolactam. The non-zeolitic molecular sieves can achieve improved conversion rates and selectivities as compared with conventional zeolite catalysts for the reaction.
