| titleOfInvention | Method for producing 1,3-dialkyl-2-imidazolidinones |
| abstract | PROBLEM TO BE SOLVED: To provide a direct one-stage reaction from an inexpensive starting material, an alkylene carbonate and a monoalkylamine, to give 1,5. 3-Dialkyl-2-imidazolidinones in high yield, It provides an improved process that has fewer by-products and can be easily implemented in large-scale industrial production. SOLUTION: The alkylene carbonate and the monoalkylamine are heated to 50 ° C or higher in the presence of an alkylamine salt of an alkyl carbamic acid. A method for producing 3-dialkyl-2-imidazolidinones. |
