Title:
METHOD FOR PREPARING Ε-CAPROLACTONE
Document Type and Number:
WIPO Patent Application WO/2018/049733
Kind Code:
A1
Abstract:
A method for preparing ε-caprolactone is provided. The method comprises the following steps: adding a cyclohexanone, an auxiliary oxidant, a certain amount of catalyst and a molecular oxygen as an oxidant into a certain amount of organic solvent, wherein the auxiliary oxidant is an acrolein, and the catalyst is a carbon material; stirring the reaction for 0.1-24 h under a pressure of 0.1-2 MPa and a temperature of 60-100°C. The method has the advantages of using a high efficiency auxiliary oxidant, an easily available and recovered catalyst, and an environmentally friendly oxidant, simple operation and low cost.
