a—甲基丙烯酸甲酯是多种化工产品的中间体,对其含量的准确分析是提高以a—甲基丙烯酸为原料的多种化工产品质量的重要手段。对a—甲基丙烯酸甲酯的分析方法一直采用皂化法,该法分析时间长,试剂药品用量大,往往由于未反应完组份的影响,使分析结果不能正确地反映其真实量。为解决这个问题,我们拟定了“气相色谱法分析a—甲基丙烯酸甲酯”的研究课题,通过反复的试验及一年来的生产实践,证明气相色谱法能有效地解决a—甲基丙烯酸甲酯的分析问题。采用氢火焰鉴定器,在一根色谱柱上,十分钟内就能同时测定a—甲 Methyl methacrylate is an intermediate for many chemical products. Accurate analysis of its content is an important means to improve the quality of various chemical products based on a-methacrylic acid. The method for the analysis of a-methyl methacrylate has been using saponification method, the analysis of a long time, a large amount of reagent drugs, often due to the impact of unreacted components, the analysis results can not correctly reflect the true amount. In order to solve this problem, we developed a “gas chromatographic analysis of a-methyl methacrylate” research project, through repeated tests and a year of production practice, proved that gas chromatography can effectively solve the a-methyl methacrylate Analysis of esters. Using hydrogen flame detector, on a column, within ten minutes can be simultaneously measured a-A
