Product Information

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.

Weinheim: Wiley-VCH. pp.1–16. doi: 10.1002/14356007.a27_419.pub2. The etymology of "vinyl" is the Latin vinum = " wine", and the Greek word "hylos" 'υλος (matter or material), because of its relationship with ethyl alcohol. Transvinylation is also possible using vinyl acetate. It undergoes Diels-Alder reactions with dienes.

An industrially important example is vinyl chloride, precursor to PVC, [3] a plastic commonly known as vinyl. Vinyl acetate was once mainly prepared by hydroesterification, i.e., the addition of acetic acid to acetylene in the presence of metal catalysts. Using mercury(II) catalysts, vinyl acetate was first prepared by Fritz Klatte in 1912. [3] Presently, zinc acetate is used as the catalyst: Effortlessly transform your home with our diverse selection of luxury vinyl flooring.

Vinyl acetate is the acetate ester of vinyl alcohol. Since vinyl alcohol is highly unstable (with respect to acetaldehyde), the preparation of vinyl acetate is more complex than the synthesis of other acetate esters.

The modern term was coined by German chemist Hermann Kolbe in 1851, who rebutted Liebig's hypothesis. [5] However even in 1860 Marcellin Berthelot still based the name he coined for acetylene on Liebig's nomenclature and not on Kolbe's. The radical was first reported by Henri Victor Regnault in 1835 and initially named aldehydène. Due to the incorrect measurement of the atomic mass of carbon it was believed to be C 4H 6 at the time. Then in 1839 it was renamed by Justus von Liebig to " acetyl", because he believed it to be the radical of the acetic acid.

Beta-hydride elimination would generate vinyl acetate and a palladium hydride, which would be oxidized to give hydroxide.

Agency for Toxic Substances and Disease Registry, Centers for Disease Control. It has a sweet, pleasant, fruity smell, but the odor may be sharp and irritating to some people. Vinyl acetate undergoes many of the reactions anticipated for an alkene and an ester. Bromine adds to give the dibromide. Hydrogen halides add to give 1-haloethyl acetates, which cannot be generated by other methods because of the non-availability of the corresponding halo-alcohols. Acetic acid adds in the presence of palladium catalysts to give ethylidene diacetate, CH 3CH(OAc) 2. It undergoes transesterification with a variety of carboxylic acids. [12] The alkene also undergoes Diels–Alder and 2+2 cycloadditions.
