正丙醇是生产丙戊酸钠、丙硫咪唑及作为生产酯类、醚类、醇类和黄原酸盐等医药化工的重要有机原料,我国尚不生产,靠国外进口。在产品质量检查中,国内化学试剂采用馏程法馏程范围96～98℃,馏出体积大于95％,我们在分析正丙醇过程中,发现用馏程法测其含量无法保证质量,为此采用毛细管气相色谱法对正丙醇进行了定性定量分析, Propanol is the production of sodium valproate, albendazole and as an important organic raw materials for the production of esters, ethers, alcohols and xanthogenates, etc. China is not yet produced and imported by foreign countries. In the product quality inspection, the domestic chemical reagents distillation range distillation range of 96 ~ 98 ℃, the distillation volume is greater than 95%, we in the analysis of n-propanol, found that the distillation range method to measure its content can not be guaranteed quality is This using capillary gas chromatography qualitative and quantitative analysis of n-propanol,
