Title:
シクロヘキサンの触媒酸化
Document Type and Number:
Japanese Patent JP2012512225
Kind Code:
A
Abstract:
The invention is directed to a method for preparing a mixture comprising cyclohexanol and cyclohexanone. In accordance with the invention a mixture comprising cyclohexanol and cyclohexanone is prepared in a molar cyclohexanone/cyclohexanol ratio of at least 1.2 at a cyclohexane conversion of below 5 mol%. The method comprises oxidising cyclohexane in a liquid phase, said oxidising being catalysed by a cobalt compound and a chromium compound, wherein the atomic cobalt to chromium ratio is in the range of 0.05-0.8, wherein the sum of the concentrations of cobalt and chromium is 0.05-0.9 ppm by weight based on the total weight of the reaction mixture, and wherein the cobalt compound and chromium compound are dissolved in the liquid phase.
