| titleOfInvention | Process for preparing N,N'-substituted urea derivatives using cerium dioxide catalyst |
| abstract | The present invention relates to a process for producing an N, N'-substituted urea derivative, characterized in that an amine derivative and carbon dioxide are reacted in the presence of a cerium oxide catalyst. In the present invention, a high yield of N, N'-substituted urea can be prepared according to the reaction conditions by using cerium oxide as a catalytically active component and using an amine compound as a starting material to carry out a carboxylation reaction in a carbon dioxide gas atmosphere, The catalyst used can be easily separated and reused after the reaction. |
