摘要：
The present invention pertains to a novel method for preparing a carbamate, in which the method comprises reacting an aliphatic substituted urea and/or its derivatives, with a hydroxyl group containing compound to obtain a carbamate. In addition, the present invention provides a novel catalyst which is suitable for catalyzing the reaction to form a carbamate, and a method for preparing the novel catalyst. The method of the present invention for preparing a carbamate does not involve the application of carbon monoxide which is toxic, and the reaction conditions are relatively mild with high catalytic activity, high reaction selectivity of the catalyst, and a relatively short reaction time. Furthermore, the catalyst is separated from the reaction system and reused easily, which will facilitates scale up and industrial application.
