标准摘要
[中文适用范围]： 1 适用范围 本文件规定了采用气相色谱法测定工业用环氧丙烷中环氧丙烷含量及微量杂质的测试方法。本方法适用于通过乙苯共氧化法（PO/SM）、异丁烷共氧化法（PO/TBA）、异丙苯共氧化法（CHPPO）、过氧化氢氧化法（HPPO）及氯醇法生产的环氧丙烷的测定。 本方法适用于纯度≥99.70%、杂质含量≥0.0003%的环氧丙烷的分析检测。 [外文原描述]： This document specifies a test method for the determination of propylene oxide and trace impurities in propylene oxide for industrial use by gas chromatography. This document is suitable for the determination of propylene oxide which is produced by ethylbenzene co-oxidation (PO/SM), isobutane co-oxidation (PO/TBA), cumene co-oxidation (CHPPO), hydrogen peroxide oxidation (HPPO) and chlorohydrin. This document is applicable for determination of propylene oxide with a purity ≥ 99,70 % and impurity content ≥ 0,000 3 %.
