GB/T 13549-2016Chlorsulphonic acid for industrial use (English PDF)

Foreword

This standard is drafted in accordance with the rules given in GB/T 1.1-2009. This standard replaces GB/T 13549-2008 "industrial chlorosulfonic acid", compared with GB/T 13549-2008 main technical changes are as follows: - modified the contents of the normative reference document (see Chapter 2, Chapter 2 of the.2008 edition);

--- modified the appearance of the superior product requirements, modified the qualified products of chlorosulfonic acid and sulfuric acid quality index value, remove the excellent goods and a (See Chapter 3, Chapter 3 of the.2008 edition); - The chemical method for the determination of the mass fraction of chlorosulfonic acid and sulfuric acid was changed from chemical titration to potentiometric titration (see 4.3, And 4.3); - the analytical steps of the potentiometric titration have been modified (see 4.3.1.4,.2008, 4.3.4); - the formula for the determination of the mass fraction of chlorosulfonic acid and sulfuric acid (see 4.3.3,.2008 4.2.5); - modified the contents of the inspection rules (see Chapter 5, Chapter 5 of the.2008 edition);

--- modified the contents of the logo, packaging, transportation and storage (see Chapter 6, Chapter 6 of the.2008 edition);

--- modified the contents of the security (see 7.5,.2008 version 7.5). This standard is proposed by the China Petroleum and Chemical Industry Association. This standard is under the jurisdiction of the National Committee for the Standardization of Sulfuric Acid and Sulfuric Acid (SAC/TC63/SC7). The drafting of this standard. Nanhua Group Research Institute, Zhejiang Juhua Co., Ltd. sulfuric acid plant, Shandong Province Product Quality Inspection Research Institute, Zhejiang Jiangjia Chemical Energy & Chemical Co., Ltd. The main drafters of this standard. Zheng Xuegen, Qiu Ailing, Zou Huiling, Zhang Yong, Wu Penglai, Shi Yingjun, Xia Bibo, Dai Rukang, Lin Li, Guan Juan. This standard replaced the previous version of the standard release.

--- GB/T 13549-1992, GB/T 13549-2008. Industrial chlorosulfonic acid Warning

--- chlorosulfonic acid in the air smoke, and water can react violently, release a lot of heat, and even explosion. Used in this standard Some reagents are toxic or corrosive and are partially hazardous. This standard does not disclose all possible security issues, the user should be strict In accordance with the relevant provisions of the correct use, and the responsibility to take appropriate safety and health measures.

1 Scope

GB/T 13549-2016 is the Chinese national standard on chlorsulphonic acid for industrial use, in the field of chemical technology. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 13 October 2016 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 May 2017. Classification: ICS 71.060.30, CCS G11. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This standard specifies the requirements for industrial chlorosulfonic acid, test methods, inspection rules and marking, packaging, transportation, storage and safety. This standard is applicable to industrial chlorosulfonic acid prepared by the synthesis of gaseous sulfur trioxide and hydrogen chloride.
