Introduction
1. Standard Overview
GB/T 5177-2017 "Industrial Linear Alkylbenzene" is a national standard of the People's Republic of China, applicable to industrial linear alkylbenzene produced by dehydrogenation and cracking methods. This standard replaces the previous GB/T5177-2008, adding the determination method of linear alkylbenzene content and other physical and chemical index requirements.
2. Standard formulation background and technology evolution analysis
With the continuous development of the detergent industry, higher requirements are placed on the quality and performance of industrial linear alkylbenzene. The revision of GB/T 5177—2017 mainly focuses on the following aspects:
- Added technical indicators for linear alkylbenzene content
- Improved the detection method, including the newly added linear alkylbenzene content determination in Appendix E
- Optimized the biodegradability requirements
3. Standard Framework Comparison Table
| Standard Version | Main Changes | New Content |
|---|---|---|
| GB/T 5177—2008 | Not including linear alkylbenzene content requirements | None |
| GB/T 5177—2017 | The linear alkylbenzene content (mass fraction) index has been added | New Appendix E, Determination of linear alkylbenzene content |
4. Implementation suggestions
Production units:Should strictly follow the standard requirements for raw material procurement, production and inspection to ensure that product quality meets the requirements of GB/T 5177—2017.
Testing agencies:It is recommended to establish a complete laboratory system equipped with advanced instruments and equipment (such as gas chromatographs, spectrophotometers, etc.) to ensure the accuracy and reliability of test data.
Regulatory authorities:Should strengthen supervision and random inspections of the market, especially the supervision of linear alkylbenzene content and biodegradability, and severely crack down on unqualified products entering the market.
