摘要
采用气相色谱-质谱联用及程序升温的方法对一氧化碳低压气相催化合成碳酸二乙酯反应产物进行了分析。实现了对PdCl2 CuCl2/活性炭上催化合成碳酸二乙酯反应的主要产物碳酸二乙酯、副产物1,1 二乙氧基乙烷、乙酸乙酯、氯甲酸乙酯、乙酸的定性,并从反应机理进行了解释。
The products in diethyl carbonate synthesis from carbon monoxide and ethyl nitrite in gas phase under normal pressure were analyzed by gas chromatography-mass spectrometry(GC-MS). Diethyl carbonate (DEC), ethanol, ethyl chloroformate, ethyl acetate, acetic acid, 1,1-diethoxyethane were separated and qualitatively analyzed respectively, and explained the formation of the by-products from the reaction mechanism.
