摘 要:碳酸二乙酯是有机碳酸酯中的重要成员,具有极高的工业价值
传统的合成碳酸二乙酯的方法在经济和工艺上都有或多或少的不足,而尿素乙醇醇解法制备碳酸二乙酯是一种新的合成工艺,原料价廉价易得、制备过程无污染、易分离,有效地降低了碳酸二乙酯的生产和环保成本,是一种绿色化学过程
关 键 词:碳酸二乙酯;醇解法;绿色化学过程Abstract : As an important organic carbonate , diethyl carbonate has extensive application value in many industrial fields because of its unique chemical structure
The traditional method for synthesis of diethyl carbonate has more or less deficiencies in synthetic process and economy
The synthesis of diethyl carbonate from urea and alcohol is a new synthetic process
The raw materials are facile and low-cost , the preparation process is clean , the product is easy to separate , which can effectively reduce the cost of production and environmental cost
So the method is a green chemical process
Key words:Diethyl carbonate ; Alcohol
