Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard replaces GB/T 5177-2008 "industrial linear alkyl benzene", and GB/T 5177-2008 The main differences are as follows. --- Increased physical and chemical indicators. Linear alkyl benzene content (see 4.1); --- Increasing the determination of linear alkyl benzene content (see Appendix E). This standard proposed by the China Light Industry Federation. This standard by the National Surfactants and Detergents Standardization Technical Committee (SAC/TC272) centralized. This standard drafting unit. Sinopec Jinling Petrochemical Co., Ltd., surfactant and detergent industry productivity promotion Center, China Daily Chemical Industry Institute. The main drafters of this standard. Huang Aizhong, Wang Wanyu, Li Xiaohui. This standard replaces the standards previously issued as. --- GB/T 5177.1-1993, GB/T 5177.2 ~ 5177.4-1985, GB/T 5177.5-2002; --- GB/T 5177-2008. Industrial linear alkyl benzene

1 Scope

This standard specifies the requirements of industrial linear alkyl benzene, test methods, inspection rules and signs, packaging, transportation, storage requirements. This standard applies to dehydrogenation and cracking method of industrial production of linear alkyl benzene, the product mainly for the production of synthetic detergent.
