GB/T 7717.12-2022 Acrylonitrile for industrial use—Part 12:Determination of purity and impurities—Gas chromatographic method
Abstract
This document specifies the gas chromatography method for determining the purity and impurity content of acrylonitrile used in industry. These impurities include acetaldehyde, acetone, acrylaldehyde, benzene, methacrylonitrile, acetonitrile,
oxazole, propionitrile, cis-butene nitrile, and trans-butene nitrile, etc.
This document is applicable to the determination of acrylonitrile samples with a purity of not less than 99% (by mass), where Condition 1 in Table 1 is suitable for the determination of impurities and acrylonitrile purity with a content of not less than 10.0 mg/kg, and Condition 2 is suitable for the determination of impurities (except methacrylonitrile) with a content of 2.0 mg/kg to 10.0 mg/kg.
