Products Description of Ethyl Vinyl Ether CAS#109-92-2
Ethyl vinyl ether is a colorless liquid that's flammable and highly reactive. Since it can easily polymerize—whether as a liquid or a gas—industrial versions usually include polymerization inhibitors to keep it stable during storage.
It freezes at -115°C, boils at 35–36°C, and melts at -115.8°C. Its relative density is 0.754 (20/20°C), with a refractive index of 1.3767. It has a flash point of -45.5°C, an autoignition temperature of 201.66°C, and a viscosity of 0.22 mPa·s at 20°C.
It's only slightly soluble in water—about 0.9% by weight—and its flammable range in air is between 1.7% and 28% by volume.

Product Application of Ethyl Vinyl Ether CAS#109-92-2
Ethyl vinyl ether is used in medicine as an anesthetic and pain reliever. It's also an important intermediate for making fine chemicals and sulfadiazine. On top of that, it's used as a monomer for making copolymers, a raw material in organic synthesis, and an ingredient in fragrances and lubricant additives.
