本研究擬開發一種生產己內酯的製程。其方法以己二酸二甲酯為原料,先透過脫甲醇形成6-羥基己酸甲酯,再脫甲醇合環成己內酯,所用的觸媒是銅-錳-鋁觸媒、釕-錫觸媒和釕-錫-鈷觸媒。;Polycaprolactone has good biodegradability and biocompatibility and is widely used in industrial, medical, packaging and environmental protection materials. With the increasing demand for biomedical and environmental protection, the demand for polycaprolactone is gradually expanding. Therefore, polycaprolactone is a highly promising chemical product. Since the production process of caprolactone monomer is more complicated and costly, most manufacturers use more common and easy to produce monomers in the production of polycaprolactone, which leads to the short supply of caprolactone monomer in the market today.
In this study, we propose to develop a process for the production of caprolactone. The method is based on the formation of methyl 6-hydroxycaproate from dimethyl adipate by demethanolization, followed by demethanolization to form caprolactone using copper-manganese-aluminum, ruthenium-tin and ruthenium-tin-cobalt catalysts.
