色谱法确定尿素甲醇法合成碳酸二甲酯的最佳工艺条件

Determination of the Best Synthesis Condition for Dimethyl Carbonate from Urea and Methanol by Gas Chromatography

用色谱法对尿素甲醇法合成碳酸二甲酯的反应产物进行定性定量跟踪分析。讨论了温度、尿素与甲醇配比、压力等因素对合成碳酸二甲酯的影响,并确定了最佳工艺条件。

The article analysed the reaction products for synthesizing dimethyl carbonate (DMC) from urea and methanol in qualitative and quantitative by gas chromatography, discussed the factors such as temperature,proportion of urea and methanol and pressure, etc, which affected the synthesis of dimethyl carbonate .Then determined the best technical condition.
