Method for producing epsilon-caprolactam by Beckmann-rearrangement in the gas phase in the presence of a pentasil-type zeolite |
摘要 |
The present invention provides a method which can produce µ-caprolactam with a good selectivity by reacting cyclohexanone oxime with a good conversion in a vapor phase Beckmann rearrangement reaction. Disclosed is a method for producing µ-caprolactam, which comprises performing a vapor phase Beckmann rearrangement reaction of cyclohexanone oxime in the presence of a pentasil type zeolite, wherein the pentasil type zeolite is a zeolite obtained by subjecting a mixture containing a silicon compound, water, and a compound represented by formula (I):
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ [(R 1 ) 3 N+-(CH 2 ) m -N+(R 1 ) 2 -(CH 2 ) m -N+(R 1 ) 3 ]-3/n (A)€ƒ€ƒ€ƒ€ƒ€ƒ(I)
wherein R 1 represents an alkyl group having 1 to 4 carbon atoms, A represents an n-valent anion, m represents an integer of 5 to 7, and n represents an integer of 1 to 3, to a hydrothermal synthesis reaction. |
