冰醋酸成分的毛细管气相色谱法测定

CONTENTS DETERMINATION OF GLACIAL ACETIC ACID BY CAPILLARY GAS CHROMATOGRAPHY

提出了用毛细管气相色谱同时测定冰醋酸中乙酸、甲酸、甲醛、醋酐和水分含量的方法；所测结果与化学分析结果十分接近，具有较满意的准确度和精确度。

A new analytic method of capillary column GC, by which the contents of acetic acid, formic acid, methanal, acetic anhydride and water in glacial acetic acid could be determined simultaneously, had been developed; the results determined by the method was very similar to the ones by chemical method. The accuracy and pricision were satisfactory.
