Basic dataStandard ID: SH/T 1492-2020 (SH/T1492-2020)Description (Translated English): 1-Butene for industrial use. Determination of Purity and hydrocarbon impurities Gas chromatographic method Sector / Industry: Petrochemical Industry Standard (Recommended) Classification of Chinese Standard: G17 Classification of International Standard: 71.080.10 Word Count Estimation: 9,929 Date of Issue: 2020-12-09 Date of Implementation: 2021-04-01 Older Standard (superseded by this standard): SH/T 1492-2004; SH/T 1548-2004 Quoted Standard: GB/T 3723; GB/T 6023; GB/T 8170; SH/T 1142; SH/T 1483; SH/T 1493; SH/T 1494 Regulation (derived from): Ministry of Industry and Information Technology Announcement No. 48 (2020) Issuing agency(ies): Ministry of Industry and Information Technology Summary: This standard specifies the use of gas chromatography to determine the purity of 1-butene for industrial use and the content of hydrocarbon impurities. This standard applies to the purity not less than 99.00% (mass fraction), and the content of hydrocarbon impurities such as propane, propylene, isobutane, n-butane, acetylene, trans-2-butene, isobutene, cis-2-butene, etc. is not less than 0.001% (mass fraction), propadiene, propyne content not less than 2mL/^3, 1,3-butadiene content not less than 10 mL/resistant or 0.001% (mass fraction) for industrial 1-butene test Sample determination. Since this standard cannot determine all possible impurities such as oxygenated compounds, isobutylene dimer, water, etc., other test methods need to be applied to fully characterize 1-butene samples.
