Introduction
Interpretation of GB/T33386-2016 Industrial 2,3,3,3-tetrafluoropropene Standard
| Items | Technical indicators (superior products) | Technical indicators (qualified products) |
|---|---|---|
| 2,3,3,3-tetrafluoropropene content (w/%) | ≥99.8 | ≥99.5 |
| Water content (w/%) | ≤0.001 | ≤0.001 |
| Acidity (as HC l,w/%) | ≤0.0001 | ≤0.0001 |
| Evaporation residue (w/%) | ≤0.005 | ≤0.01 |
Case Study: Application of Gas Chromatography in Content Determination
The content of 2,3,3,3-tetrafluoropropene was determined using a gas chromatograph (with hydrogen flame ionization detector). The measurement accuracy was ensured to be within ±0.1% by standard curve and correction area normalization method. This method is particularly suitable for industrial applications with high purity requirements.
