Introduction
Core changes in the standard revision
| Technical indicators | SH/T0417-92 | NB/SH/T0417-2013 | Technical significance |
|---|---|---|---|
| Standard Name | Liquid Paraffin | Light Liquid Paraffin | Clear product density range |
| N-alkane content | Not specified | ≥98.5% | Increase raw material purity requirements |
| Testing items | Distillation range, mechanical impurities | Carbon number distribution, bromine index and other 5 new items | Improve the quality control system |
Analysis of key technical indicators
Bromine index ≤ 25mgBr/100g: Determined by SH/T0630 coulometric method, this indicator reflects the content of unsaturated hydrocarbons and directly affects the application performance of the product in ethylene cracking raw materials.
Carbon number distribution detection: SH/T0410 gas chromatography is used to ensure that the molecular weight distribution of light liquid paraffin meets the process requirements of downstream plasticizer production.
Key points for safety implementation
According to the classification of GB13690, this product belongs to the third category flammable liquid. Attention should be paid to transportation and storage:
- The packaging container should be marked with the dangerous goods symbol specified in GB190
- The storage temperature should not exceed 45℃
- Store away from oxidants
Industry application suggestions
The chemical enterprise response plan for the implementation of the new version of the standard:
- Suppliers are required to provide a complete carbon number distribution report when purchasing raw materials
- The laboratory is equipped with SH/T0630 bromine index tester
- Establish a UV spectrophotometric detection process for aromatic content
