<p><P>PROBLEM TO BE SOLVED: To provide a method for preparing a urea compound by fixing carbon dioxide. <P>SOLUTION: This invention relates to a method for preparing the urea compound by reacting a carbon dioxide raw material with an amine compound raw material by a reaction system with a medium containing at least carbon dioxide as a reaction medium, chemically fixing carbon dioxide to the amine compound, and synthesizing the urea compound corresponding to the amine compound raw material. This invention also relates to a method for preparing the urea compound by synthesizing the urea compound corresponding to the amine compound with water in which carbon dioxide is dissolved or carbon dioxide containing water as the reaction medium. According to this invention, the corresponding urea compound can be synthesized at a high selection rate from the amine compound by the carbon dioxide fixation process. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
