Products Description of Ethyl Vinyl Ether CAS#109-92-2
Ethyl vinyl ether is a clear, colorless, and highly flammable liquid characterized by its strong chemical activity. It is prone to polymerization in both liquid and vapor states, so industrial-grade products are generally formulated with polymerization inhibitors to minimize unwanted polymerization and improve storage stability.
Ethyl vinyl ether has a freezing point of -115℃ and a boiling range of 35–36℃, with a melting point of -115.8℃. Its relative density is 0.754 (20/20℃), and its refractive index is 1.3767. The flash point is -45.5℃, the autoignition temperature is 201.66℃, and the viscosity is 0.22 mPa·s at 20℃.
The compound has limited solubility in water, at approximately 0.9% by weight, while its flammable concentration range in air is 1.7%–28% by volume.
