摘要
本实验建立全自动卡尔费休水分测定仪快速测定普通柴油中微量水分的方法,并且评价了普通柴油对甲醇、三氯甲烷、正庚烷、四氯化碳等有机溶剂的选择性,经实验证明采用甲醇-三氯甲烷二元混合体系,配比为1:3进行普通柴油中微量水分测定,操作快速简便,结果稳定可靠。
The study aims to establish the rapid analysis method to determine water in general diesel fuels by antomatic Karl Fischer method. The experiment evaluated the general diesel fuels with methanol, Trichloromethane, n-heptane, carbon tetrachloride of selectivity. It proved by the experiment using methanol-chloroform binary mixed system with 1：3 matching for the determination of trace moisture in general diesel fuels, which have quick and easy operation, stable and reliable results.
