Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard replaces GB 17602-1998 "Industrial Hexane". Compared with GB 17602-1998, the main technical changes except editorial changes The following is as follows:

--- Standard changed from mandatory to recommended;

--- Increased product classification (see Chapter 3 and Table 1);

--- Increased n-hexane content requirements (see Table 1);

--- Increased the requirements of sulfur content, bromine index and benzene content indicators (see Table 1);

--- Modify the distillation range indicators and test methods (see Chapter 2 and Table 1);

--- Increased test method for benzene content (see Chapter 2 and Table 1);

--- Added inspection rules and security content (see Chapters 5 and 7). This standard is proposed and managed by the National Petroleum Products and Lubricants Standardization Technical Committee (SAC/TC280). This standard was drafted. Petrochemical Research Institute of China Petroleum and Chemical Corporation, Nanjing Zhongshang Huatian Petrochemical Co., Ltd. Sinopec Jinling Branch. The main drafters of this standard.

1 Scope

GB/T 17602-2018 is the Chinese national standard on commercial hexanes, in the field of petroleum and related technologies. 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 28 December 2018 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 1 July 2019. Classification: ICS 75.140, CCS E33. 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 product classification, requirements and test methods, inspection rules, signs and packages of industrial hexanes prepared from petroleum fractions. Loading, transportation, storage and safety. This standard applies to chemical synthesis (such as the polymerization of polypropylene, polybutylene and ethylene propylene rubber) process with hexane solvent and preparation of binder, coating Materials, inks and industrial hexanes used in various extraction processes. This standard does not apply to edible vegetable oils and hexanes for protein extraction.
