| Abstract: | The synthesis of ethyl carbomate from urea and ethanol by the alcoholysis of urea in autoclave was investigated.The effects of temperature,time,initial pressure,and the feed molar ratio of ethanol to urea on the reaction were observed,and the optimized reaction parameters were determined as follows:feed molar ratio of ethanol to urea 4∶1,reaction initial pressure 1.2 MPa,reaction temperature 170 ℃,and keeping reaction 1.5 hours at the temperature.Under the optimized reaction conditions,the yield of ethyl carbomate was up to 87.1%. |
