Description
Specification:
| Index | Standard |
|---|---|
| Content (by GC) | ≥99.0% |
| Water (H₂O) | ≤0.05% |
| Appearance | Colorless to pale yellow liquid |
Properties:
- Chemical Behavior: Highly reactive, moisture-sensitive liquid that decomposes in water (violent reaction).
- Solubility: Miscible with organic solvents (e.g., ether, benzene, DCM) but reacts with protic solvents (e.g., water, alcohols).
- Stability: Stable under anhydrous conditions; decomposes at high temperatures (>150°C).
Application:
- Pharmaceuticals: Key intermediate for synthesizing antibiotics and peptide-based drugs.
- Agrochemicals: Production of herbicides (e.g., oxadiazon) and pesticides.
- Organic Synthesis: Chlorination agent for converting carboxylic acids to acyl chlorides. Used in Friedel-Crafts acylation and dye manufacturing.
- Electrolyte Additives: Stabilizer for lithium-ion battery electrolytes (e.g., LiPF₆).
Package and Storage:
- Packaging: 250 kg/drum (steel or HDPE with PTFE lining).
- Storage: Store under dry inert gas (N₂/Ar) in a cool (<25°C), ventilated area. Avoid: Moisture, heat, and contact with water/alcohols.
