Introduction
In-depth interpretation of GB/T 693-2024 "Chemical reagent sodium acetate trihydrate (sodium acetate)" standard
This standard is an important specification in the field of chemical reagents, and comprehensively updates the technical requirements, test methods and inspection rules for sodium acetate trihydrate. Compared with the 1996 version, the new standard has significantly improved technical indicators, test methods and quality control, aiming to ensure the high quality and safety of chemical reagents.
Comparative analysis of standard frameworks
| Item | Excellent purity | Analytically pure | Chemically pure |
|---|---|---|---|
| Sodium acetate trihydrate (CH3COONa·3H2O) content, w/% | ≥99.5 | ≥99.0 | ≥98.0 |
| pH value (50 g/L, 25 °C) | 7.5~9.0 | 7.5~9.0 | 7.5~9.0 |
| Clarity test/number | ≤2 | ≤3 | ≤5 |
Standard formulation background and technology evolution analysis
Sodium acetate trihydrateAs an important chemical reagent, it is widely used in laboratory and industrial applications. The revision of the new version of the standard is based on the following background:
- The technical indicators of the old standard can no longer meet the needs of modern high-precision experiments
- Added a number of new detection methods (such as flame atomic absorption spectrometry, inductively coupled plasma atomic emission spectrometry)
- Optimize the quality control process and improve the purity and stability of reagents
Implementation suggestions
Actual application case:When a laboratory purchases sodium acetate trihydrate, it needs to choose the appropriate purity grade (superior pure, analytical pure or chemical pure) according to the specific purpose. For example:
- For high-end scientific research projects, it is recommended to use superior pure products to ensure the accuracy of experimental results.
- In industrial production, if the purity requirements for reagents are not high, chemically pure products can be selected to reduce procurement costs.
