Will show some signs that it was played and otherwise handled by a previous owner who took good care of it. Transvinylation is also possible using vinyl acetate. It undergoes Diels-Alder reactions with dienes. Tomotaka Hirabayashi; Satoshi Sakaguchi; Yasutaka Ishii (2005). "Iridium-catalyzed Synthesis of Vinyl Ethers from Alcohols and Vinyl Acetate". Org. Synth. 82: 55. doi: 10.15227/orgsyn.082.0055. Vinyl acetate is an organic compound with the formula CH 3CO 2CH=CH 2. This colorless liquid is the precursor to polyvinyl acetate, ethene-vinyl acetate copolymers, polyvinyl alcohol, and other important industrial polymers. [3] Production [ edit ] On January 31, 2009, the Government of Canada's final assessment concluded that exposure to vinyl acetate is not harmful to human health. [13] This decision under the Canadian Environmental Protection Act (CEPA) was based on new information received during the public comment period, as well as more recent information from the risk assessment conducted by the European Union.

Chemical structure of the vinyl functional group.The major industrial route involves the reaction of ethylene and acetic acid with oxygen in the presence of a palladium catalyst.

Vinyl derivatives are alkenes. If activated by an adjacent group, the increased polarization of the bond gives rise to characteristic reactivity, which is termed vinylogous: Isotope labeling and kinetics experiments suggest that the mechanism involves PdCH 2CH 2OAc-containing intermediates. Beta-hydride elimination would generate vinyl acetate and a palladium hydride, which would be oxidized to give hydroxide. [7] Alternative routes [ edit ] Constable, Edwin C.; Housecroft, Catherine E.

In the context of large-scale release into the environment, it is classified as an extremely hazardous substance in the United States as defined in Section302 of the U.S. Emergency Planning and Community Right-to-Know Act ( 42 U.S.C. 11002), under which it "does not meet toxicity criteria[,] but because of its acute lethality, high production volume [or] known risk is considered a chemical of concern". By this law, it is subject to strict reporting requirements by facilities that produce, store, or use it in quantities greater than 1000pounds.
