HG/2974—1999
This standard is revised from HG/T2974—1988, a national standard. Compared with HG/T2974—1983, the standard has been revised in terms of text and technical content. From the date of implementation, this standard replaces HG/2974—1993. This standard was proposed by the Technical Supervision Bureau of the former Ministry of Chemical Industry of the People's Republic of China. This standard was drafted by the National Chemical Standardization Technical Committee and the main drafters of this standard, Jiangshan Chemical Plant. The main contributors to this standard are: Sun Jianmin, Tai Xinfang, Chu Yuhua, Liu Ying and Zhu Daozhang. This standard was first issued as a national standard in 1988, and was promoted as a national standard in 1997. It was newly confirmed by the National Chemical Standardization Technical Committee. This standard contains organic components with negative volatile organic compounds. Scope: Chemical Industry Standard of the People's Republic of China: Solutlons of oy: trimethylamine for industrial uae HG/T 2974—1999 Code: G71-19 This standard specifies the requirements for sampling, test methods, marking, color, transportation and storage of 3-hydroxy-3-methylamine aqueous solutions prepared from diamine. This standard applies to the three-component modified liquid produced by the gas phase catalytic catalysis of methanol. The molecular formula is (CHN
) The molecular weight is: 59.11 (according to the 1995 International Standard for Atomic Mass 2 References
