PURPOSE:To readily obtain the subject compound useful as a now material for nylon, etc., in a high selectivity in the elongated life of a catalyst by reacting cyclohexanone oxime in the presence of a solid acid catalyst and in the coexistence of an ether compound under a gaseous reaction condition. CONSTITUTION:Cyclohexanone oxime is subjected to a gaseous phase rearrangement reaction in the presence of a solid acid catalyst, especially a silicon oxide- containing catalyst such as crystalline aluminosilicate having a Si/Al atom ratio of >=5, preferably in a weight ratio of 0.3-15 times the weight of the cyclohexanone oxime in the coexistence of an ether compound of a formula: R1-O-R2 (R1 is CH3 or C2H5; R2 is 1-6C alkyl or phenyl) such as methyl tertbutyl ether, diethyl ether or anisole and, if necessary, a diluting gas such as benzene especially preferably at 300-450 deg.C preferably at a feeding rate of LHSV=0.2-20 hr<-1> to provide the objective compound. The ether compound is separated and recovered for the re-use thereof. |
