Visol-6, according to Refs 2 4, was a Ger trade name for vinylethyl ether. It was used during WWII as a liq rocket propelling fuel in guided missiles such as the Enzian E-4, Rhein-tochter R-3 and Wasserfall. Absolute nitric acid was used as the oxygen carrier... 

Ref 5 defines Visol-1, -4, and -6 as vinylethyl ether and mixts with isopropyl alcohol and vinylbutyl ether... 

It has been shown [31] that the presence of hydrophobic groups in polyampholytes can change the equilibrium between the zwitterionic and molecular forms. Alternating copolymers of vinylethyl ether and N,N-diethylaminopropyl-monoamide of maleic acid preferentially exist in the charged form (I) but the replacement of ethyl radicals by two bulky butyl radicals stabilizes the uncharged molecular form (II). 

A comprehensive article related to the formation of aryl-l-(chloro-thio)formimidoyl chlorides XLI appeared recently and the reaction of XLI with a variety of amines has been reported ( ). The enormous reactivity of XLI was further evidenced by the formation of 1 1 adducts with aldehydes and vinyl ethers ( ). For example, reaction of XLI (R = C Hs) with vinylethyl ether yields 3-phenyl-1,3-thiazolin-2-one (XLII) ( ).

Ethers are relatively uncommon atmospheric pollutants, although the flammability hazard of diethyl ether vapor in an enclosed work space is well known. In addition to aliphatic ethers, such as dimethyl ether and diethyl ether, several alkenyl ethers, including vinylethyl ether, are produced by internal combustion engines. Methyltertiarybutyl ether, MTBE, became tiie octane booster of choice to replace tetraethyllead in gasoline. Because of its widespread distribution, MTBE has the potential to be an air pollutant, although its hazard is limited by its low vapor pressure. Largely because of its potential to contaminate water, MTBE was proposed for phaseout by both the state of California and the U.S. Environmental Protection Agency in 1999. Ethers are relatively unreactive and not as water-soluble as the lower alcohols or carboxylic acids.
