What Is Ethyl Vinyl Ether?
Ethyl vinyl ether is an organic compound known as ethoxyethene or 3-oxa-1-pentene. It appears as a colorless liquid with a characteristic ether odor, having the chemical formula CH2CHOC2H5. Its CAS number is 109-92-2, and it is structurally a reduced form of indole at positions 2 and 3.
Uses of Ethyl Vinyl Ether
This compound is mainly utilized as a raw monomer in polymer synthesis, a reagent in organic chemical reactions, and as an inhalant anesthetic. In polymer chemistry, ethyl vinyl ether can be polymerized to form poly ethyl vinyl ether, used in adhesives, ink materials, and coatings. As a reagent, it plays a role in various organic synthesis processes.
Properties of Ethyl Vinyl Ether
Ethyl vinyl ether has a boiling point of 36°C, a melting point of -115°C, and a flash point of -45°C. It is extremely soluble in ethanol, ether, and acetone, but almost insoluble in water. The compound is more basic than indole due to its unaltered nitrogen atom, with a pKa of 5.2.
Other Information on Ethyl Vinyl Ether
1. Toxicity of Ethyl Vinyl Ether
As an inhalation anesthetic, ethyl vinyl ether can cause dizziness and drowsiness upon inhalation. Animal studies suggest it is non-irritating to skin and eyes, but its high flammability necessitates the use of protective gloves, safety glasses, and proper handling equipment.
2. Precautions for Use of Ethyl Vinyl Ether
Due to its low flash point, ethyl vinyl ether is highly flammable and can form explosive mixtures with air. It should be kept away from heat, sparks, and open flames, and handled in a spark-free laboratory environment with appropriate electrostatic discharge measures. It reacts violently with oxidizing agents and acids, posing risks of explosion or fire.
3. Stability of Ethyl Vinyl Ether
Ethyl vinyl ether is prone to polymerization reactions under heat or light. It is typically stabilized with about 0.1% potassium hydroxide and should be stored in a cool, dark place.
4. Disposal Method
As a hazardous material, ethyl vinyl ether should not be released into the environment and must be disposed of through specialized waste disposal services.
