Title:
硫酸化処理された固体酸触媒およびその使用
Document Type and Number:
Japanese Patent JP4525418
Kind Code:
B2
Abstract:

To provide a solid acid catalyst useful for acid catalytic reaction, that is, to provide a simple preparation method of a solid acid catalyst for producing a lactam compound at a high yield in a moderate reaction condition at the time of Beckmann rearrangement reaction of a cycloalkanone oxime compound for producing a corresponding lactam compound.

The solid acid catalyst is a compounded oxide subjected to sulfation and has a peak attributed to hexagonal structure d100in a range of 2θ=2.0 to 2.5° in X-ray diffraction pattern (Cu-Kα beam) and a nitrogen adsorption capacity from 20 to 60% in the total adsorption capacity in a range of P/P0=0.2 to 0.6 in a nitrogen adsorption isotherm.
