碳酸乙烯酯与甲醇酯交换反应液相产物含量测定

摘要

采用porapak-QS为色谱固定相,建立气相色谱法测定碳酸乙烯酯与甲醇酯交换反应制碳酸二甲酯液相组分含量,并对该方法的准确性及各种影响因素进行了研究.该方法快速简便,完全适合科研及生产的需要.%Using porapa-QS as chromatographic stationary phase, a gas chromatographic method was established for quantitatively analying the components of the liquid product from the transesterification reaction of ethylene carbonate with methanol, and the accuracy of the method and various factors affacting the analysis were investigated. The method is fast, convenient and fully suitable for laboratory research and industrial production.
