摘要
建立了氯甲酸异丁酯质量内控方法。实验采用毛细管气相内标法含量测定方法,用HP-5(30 m×0.32 mm×0.25μm)毛细管气相色谱柱,FID检测器,以正辛烷为内标进行氯甲酸异丁酯测定。氯甲酸异丁酯在0.30~0.49μg/μL(r=0.999 9)范围内呈良好线性关系;氯甲酸异丁酯回收率为96.55%。采用滴定方法测定其游离酸含量。
A method for the content determination of isobutyl chloroformate was established by using capillary gas chromatography with a HP-5(30 m×0.32 mm×0.25 μm)capillary column and a flame ionization detector. Octane was used as the internal standard substance. The linear range of isobutyl chloroformate was 0.30 ~ 0.49 μg / μL(r=0.9999)and its recovery was 96.55%. Free acid was measured by titration.
