Title:
環状カーボネートを連続的に調製する方法
Document Type and Number:
Japanese Patent JP7233439
Kind Code:
B2
Abstract:
Process to continuously prepare a cyclic carbonate product by reacting an epoxide compound with carbon dioxide in the presence of a supported dimeric aluminium salen complex which complex is activated by a halide compound comprising the following steps, (a) contacting carbon dioxide with the epoxide compound in a suspension of liquid cyclic carbonate and the supported dimeric aluminium salen complex which complex is activated by a halide compound, (b) separating part of the cyclic carbonate product from the supported dimeric aluminium salen complex, (c) separating the halide compound from the cyclic carbonate product to obtain purified cyclic carbonate product, (d) use all or part of the halide compound as obtained in step (c) to activate deactivated supported dimeric salen complex.
