Methyl vinyl ether is a chemical compound selected from the group of the vinyl ether. It is the simplest members of this group and therefore is sometimes even referred to simply as vinyl ethers.

Properties

Methyl vinyl ether polymerizes easily and then forms polymethyl ( PMVE, CAS: 9003-09-2 ) with the formula ( CH3OCH - CH2 ) n

Use

Methyl vinyl ether is used as an auxiliary agent in the mass of specific chemical compounds, and as an intermediate for the preparation of other chemical compounds (eg, glutaraldehyde).

Safety

Methyl vinyl ether is highly flammable (flash point -60 ° C) and forms an explosive mixture with air. The explosion range is between 2.2 vol% (54 g/m3) as the lower explosive limit ( LEL) and 28.2 % by volume ( 694 g/m3 ) and upper explosive limit (UEL ). The ignition temperature is 220 ° C. The fabric falls within the temperature class T3. It is chemically unstable and has a tendency to spontaneous polymerization exotherm. On contact with acids and acidic substances (eg calcium chloride) to form acetaldehyde.
