GC法分析甲酸甲酯水解体系组成

Analysis of formic ether hydrolyzed system composition by GC

本文介绍了对易挥发、具腐蚀性且组份之间存在可逆反应的含有甲酸、甲酸甲酯、甲醇和水等样品的GC分析。考察了取样方式、样品保存、色谱条件及定量校正因子等因素对分析结果的影响,从而提出了具有实用价值的分析方法,相对误差<3％,标准偏差<0.2。

In this article, analysis by GC of volatile and corrosive samples containing formic acid, formic ether, methanol and water among which there may be reversible reactions is described.Factors affecting analytical results as sampling ways, storage of sanple, GC condition and correction for quantitative analysis are investigated.Thus, a practical method for analysis is put forwaed with relative error<3%, standard deviation<0.2.
