摘　　要：建立了TCD-FID检测器串联的气相色谱法同时测定低碳混合醇的组成与水含量的方法。对6种低碳混合醇的主要组成和水含量进行了分析,结果表明低碳混合醇中的含氧有机物90%以上为醇类,其中乙醇含量最高,甲醇次之,正庚醇含量最低,水含量为0.2~0.3 g/m L。A method for simultaneous determination of the compositions and water content in low-carbon mixed alcohols by gas chromatography with TCD-FID detector was developed.The main constituents and water content of six kinds of low-carbon mixed alcohols were analyzed.The results showed that more than 90%of oxygenates in low-carbon mixed alcohols were alcohols,in which the largest share was ethanol,followed by methanol,and the n-heptanol was the lowest.The water content in low-carbon mixed alcohols was about 0.2~0.3 g/mL.
