The Dual Edges of a Universal Solvent : Safe Production and Environmental Compliance of Tetrahydrofuran
Created on 2025.03.19
1. Peroxide Formation: A Hidden Danger
Tetrahydrofuran (THF), while prized as a "universal solvent" in pharmaceuticals, polymer synthesis, and electronics, carries inherent risks due to its propensity to form explosive peroxides under oxygen exposure

2. Stabilizers in Action: The Role of BHT
To mitigate peroxide generation, 2,6-di-tert-butyl-4-methylphenol (BHT) is widely employed as a stabilizer at 0.01–0.04% (w/w)
9. Its efficacy stems from:
- Radical scavenging

- Temperature resilience
3
- Analytical interference

3. Tackling VOC Emissions: From Capture to Destruction
THF’s volatility (vapor pressure: 162 mmHg at 25°C) and flammability (flash point: -15°C) demand robust VOC management
