Introduction
GB/T 35498—2017 Interpretation of the Standard for Industrial Vinyl Trichlorosilane
1. Overview of the Standard
GB/T 35498—2017 Industrial Vinyl Trichlorosilane specifies the product's quality requirements, test methods, inspection rules and safe storage, and is applicable to industrial-grade vinyl trichlorosilane produced by a variety of process routes.This standard was drafted by Zhejiang Xin'an Chemical Group Co., Ltd. and other units and is an important basis for industry norms.
2. Comparison of Technical Indicators
Table 1 lists the technical indicators of products of different quality grades, including key parameters such as chromaticity, vinyl trichlorosilane content and impurity content.It can be seen from the table that superior products have the most stringent requirements on various indicators and are suitable for high-end application fields.
| Item | Superior product | First-class product | Qualified product |
|---|---|---|---|
| Chroma/Hazen unit (platinum-cobalt color number) | ≤10 | ≤20 | ≤30 |
| Vinyltrichlorosilane, w/% | ≥99.5 | ≥99.0 | ≥98.5 |
| Silicon tetrachloride, w/% | ≤0.1 | ≤0.2 | ≤0.5 |
| Ethyltrichlorosilane, w/% | ≤0.3 | ≤0.5 | ≤1.0 |
3. Detailed explanation of the test method
The standard stipulates that gas chromatography is used to detect the mass fraction of vinyltrichlorosilane, silicon tetrachloride and ethyltrichlorosilane.Use gas chromatograph with thermal conductivity detector (TCD) and use area normalization method to calculate the content of each component.
Case study: laboratory operation precautions
When sampling, be careful to avoid contact with air and immediately seal and refrigerate. During the measurement process, it is necessary to ensure that the sensitivity and stability of the chromatograph meet the requirements, and the absolute difference of the peak area of each component is controlled within the specified range.4. Background of Standard Formulation
With the expansion of the application of silicon-based materials, the demand for vinyltrichlorosilane has increased significantly. The formulation of this standard aims to regulate product quality and ensure its safety and reliability in industrial applications.The revision and technological evolution of the standard are mainly reflected in the < strong>optimization of detection methods and the < strong>refinement of quality indicators.
5. Implementation Suggestions
To ensure the effective implementation of the standard, it is recommended that manufacturers:- Strengthen employee training and familiarize themselves with various detection methods and safe operating procedures.
- Optimize production processes, reduce impurity generation, and improve product quality levels.
- Regularly calibrate equipment to ensure the accuracy of instruments such as gas chromatographs.
