丙二酸二异丙酯是农药杀菌剂稻瘟灵的原料,其分析方法国内未见报导,国外文献也不多见。丙二酸二异丙酯的标准样制备不易,给分析带来不便。本文由理论有效碳数求得组分的校正因子,用峰面积归一化法计算产品中有效成分的百分含量,并与内标法的结果进行了比较。 Diisopropylmalonate is a pesticide fungicide rice blast raw materials, the analysis of the domestic no reports, foreign literature is rare. The preparation of the standard sample of diisopropyl malonate is not easy, which brings inconvenience to the analysis. In this paper, the correction factor of the components obtained from the theoretical effective carbon number, the peak area normalization method to calculate the percentage of active ingredients in the product, and compared with the results of internal standard method.
