A general term for ethers with the general formula CH 2 =CH-O-R. They are produced by Reppe Chemical's vinylization reaction. For example, ethyl vinyl ether, C 2 H 5 OCH=CH 2 , obtained by thermally decomposing acetal over a platinum catalyst, is a liquid with a boiling point of 35.7°C and is used in painkillers. Vinyl ethers easily undergo addition polymerization to become polyvinyl ethers. These polymers are widely used in paints, adhesives, fiber treatment agents, plasticizers, etc. [Nakai Takeshi] Source: Heibonsha World Encyclopedia, 2nd Edition Information |
一般式CH2=CH-O-Rで表されるエーテルの総称。レッペ化学のビニル化反応によってつくられる。たとえば,アセタールを白金触媒上で加熱分解して得られるエチルビニルエーテルC2H5OCH=CH2は沸点35.7℃の液体で,鎮痛剤などに用いられる。ビニルエーテル類は容易に付加重合してポリビニルエーテルとなる。この重合体は,塗料,接着剤,繊維処理剤,可塑剤などに広く用いられる。【中井 武】
