Methoxyethene Chemical Properties,Usage,Production
Description
Methoxyethene (MVE) is a colorless and flammable gas with a sweet and pleasant odor at room temperature. It is heavier than air and can diffuse to a relatively distant place at a lower place. MVE is soluble in ethanol, ether and acetone, but it is only slightly soluble in water. MVE is easily polymerized, so potassium hydroxide is often added as a polymerization inhibitor in the finished product.
Chemical Properties
Colorless compressed gas, or colorless liquid. Slightly soluble in water; soluble in alcohol and ether; easily polymerized. Commercial material contains a small proportion of polymerization inhibitor.
Uses
Methyl Vinyl Ether is a reagent in the preparation of sodium alginate interpolymer complexes, pH-tunable drug carries.
Uses
Copolymers used in coatings and lacquers; modifier for alkyl, polystyrene, and ionomer resins; plasticizer for nitrocellulose and adhesives.
General Description
A colorless gas with a sweet odor. Shipped as a liquefied gas under own vapor pressure. Contact with the liquid may cause frostbite. Easily ignited. Vapors are heavier than air. Leaks may either be liquid or vapor. May asphyxiate by the displacement of air. Under prolonged exposure to fire or intense heat containers may rupture violently and rocket.
Air & Water Reactions
Highly flammable. Reacts slowly with water to form acetaldehyde, reaction is not hazardous unless water is hot or acids are present. Form dangerous peroxides when exposed to air.
Reactivity Profile
Methoxyethene reacts vigorously with oxidizing materials. Explosive in the form of vapor when exposed to heat, flame or strong oxidizing agents. Reacts, possibly explosively with halogens (bromine, chlorine) or hydrogen halides (hydrogen bromide, hydrogen chloride) [Baker, 1980, p. 487]. On contact with dilute acids or even mildly acidic solids (calcium chloride, ceramics) undergoes rapid, exothermic homopolymerization, which cannot be prevented by antioxidants. Must be stored in the presence of base [MVE Brochure, Billingham, ICI, 1962].
Health Hazard
Inhalation causes intoxication, blurring of vision, headache, dizziness, excitation, loss of consciousness. Liquid or concentrated vapor irritates eyes and causes frostbite of skin. Aspiration of the liquid will cause chemical pneumonitis.
Fire Hazard
Behavior in Fire: Containers may explode. Vapor is heavier than air and may travel a considerable distance to a source of ignition and flash back.
Flammability and Explosibility
Extremely flammable
Safety Profile
Mildly toxic by ingestion. A very dangerous fire hazard when exposed to heat, flame, or oxiduers. Explosive in the form of vapor when exposed to heat or flame. Can react vigorously with oxidizing materials. To fight fire, stop flow of gas. Potentially explosive reaction with halogens (e.g., bromine, chlorine) or hydrogen halides (e.g., hydrogen bromide, hydrogen chloride). Reaction with acids forms acetaldehyde. Weak acids catalyze the exothermic polymerization of the ether. The unstabilized ether can form dangerous peroxides. When heated to decomposition it emits acrid smoke and irritating fumes.
Synthesis
The industrial processes of MVE production include the acetylene route (Reppe process) and the acetal route according to the starting materials.
B. MVE is prepared by pyrolysis of dimethyl acetal at high temperature in the presence of a solid catalyst. In general, the pyrolysis of dimethylacetal is carried out in the vapor phase. Dimethylacetal was vaporized and introduced into a fixed-bed reactor filled with calcium phosphate catalyst. In the reactor, dimethylacetal split into MVE and methanol at 320 °C and under atmospheric pressure. The conversion of dimethylacetal was 95%, and the selectivity to MVE was more than 98%.
