Methoxyethene Safety Profile

Mildly toxic by ingestion. A very dangerous fire hazard when exposed to heat, flame, or oxidizers. 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. See also ETHERS and PEROXIDES, INORGANIC; PEROXIDES, ORGANIC.

Methoxyethene Specification

 Methoxyethene , its CAS NO. is 107-25-5, the synonyms are 1-Methoxyethylene ; agrisynthmve ; Ethene,methoxy-;Ethenylmethylether ; ether,ethenylmethyl ; Ether, methyl vinyl . Methoxyethene (CAS NO.107-25-5) 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].
