Determination of purity and hydrocarbon impurities of butadiene for industrial use - Gas chromatographic method ICS 71.080.10 CCSG15 National Standards of People's Republic of China Replace GB/T 6017-2008 Industrial butadiene purity and determination of hydrocarbon impurities Gas chromatography Released on 2021-08-20 2022-03-01 implementation State Administration of Market Supervision and Administration Issued by the National Standardization Management Committee ForewordThis document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for Standardization Work Part 1.Structure and Drafting Rules of Standardization Documents" Drafting. This document replaces GB/T 6017-2008 "Industrial butadiene purity and hydrocarbon impurities determination gas chromatography", and GB/T 6017- Compared with.2008, the main technical changes are as follows. a) Added the chromatographic conditions of the 100mAl2O3/KCl capillary column in series (see 6.2, 5.2 in the.2008 edition); b) Modified the chromatographic conditions of the Al2O3/KCl type capillary column (see 6.2, 5.2 in the.2008 edition); c) The technical requirements of flash vaporization device are added to the sampling method (see 6.4.2); the method of completely vaporizing a small amount of liquid sample is deleted (5.3.2.1 of the.2008 version); d) Modified the determination of the mass correction factor of the correction area normalization method in the test procedure (see 8.2.1, 7.1.2 of the.2008 edition); e) Modified the expression method and calculation formula of the external standard method (see 8.3, 7.2 of the.2008 edition); f) The residues in other impurities deducted in the calculation of the purity of butadiene are modified to water, and the determination method of other impurities is added (see 8.2.3, 8.3.3, 7.1.4, 7.2.2 of the.2008 version); g) Re-determined the repeatability limit (r) (see Chapter 10, Chapter 9 of the.2008 edition); h) Added quality control (see Chapter 11); i) The chromatographic conditions in Appendix A have been deleted (see Appendix A of the.2008 edition).

Measure every The peak area of each impurity and butadiene, the mass fraction of each component is calculated by the corrected area normalization method, and the measured value will be measured by other standard methods. The total amount of impurities such as butadiene dimer, carbonyl compound, polymerization inhibitor and water are normalized to the measurement results. 4.2 External standard method Under the conditions specified in this document, a quantitative sample and an external standard are injected into a gas chromatograph equipped with FID. Measure every ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 6017-2021_English be delivered?Answer: Upon your order, we will start to translate GB/T 6017-2021_English as soon as possible, and keep you informed of the progress.
