针对近年来利用甲醇和CO2 直接反应制备碳酸二甲酯研究中反应条件苛刻、工艺设备复杂、甲醇转化率低等不足问题，本文研制一种固碳溶液，其CO2 饱和质量浓度达0.528 g/mL；在固碳溶液中用电解的方式对CO2 进行活化，并在电解过程中不断补充CO2 至饱和，得到电解活化液；用碘甲烷作诱导剂，使其与甲醇在60℃回流120 min，制得碳酸二甲酯，纯度为99.0%，转化率为99.6%（以甲醇质量计），反应过程环保、条件温和。

The method for the methanol and the carbon dioxide to directly react to prepare the dimethyl carbonate suffers from several deficiencies, such as too strict operation conditions, complex processing equipments, and low conversion rate of the methanol. A carbonabsorption solution is developed in this paper, in which the saturation concentration of the carbon dioxide reaches 0.528g/ml; the electrolysis is used to activate the carbon dioxide and in the electrolytic process the carbon dioxide is continuously added until saturation so as to obtain the electrochemical activation solution; the methyl iodide is used as the inducer, which is refluxed for 120 minutes with the methyl alcohol at 60℃, so as to obtain the dimethyl carbonate, with a purity of 99.0%, and the conversion rate of 99.5% (measured based on the amount of the methanol).
