Products Description of Ethyl Vinyl Ether CAS#109-92-2
Ethyl vinyl ether is a colourless, flammable liquid characterized by high chemical reactivity. It tends to polymerize easily in both liquid and gaseous states. For this reason, commercially supplied material is generally stabilized by polymerization inhibitors to avoid uncontrolled polymerization.
Its freezing point is -115°C, boiling range 35–36°C and melting point -115.8°C. This substance has a relative density of 0.754 (20/20°C), a refractive index of 1.3767, a flash point of -45.5°C and an autoignition temperature of 201.66°C, with viscosity reaching 0.22 mPa·s at 20°C. It is sparingly soluble in water (roughly 0.9 wt%), and its flammable concentration range in air lies between 1.7 vol% and 28 vol%.
