Product Information

Vinyl acetate is useful in organic synthesis. [9] Transacetylation is used to obtain enantioenriched alcohols and esters. Iridium-catalyzed transacetylation have also been demonstrated: [10] [11] ROH + CH 2=CHOAc → ROCH=CH 2 + HOAc Summary of Public Comments Received on the Government of Canada's Draft Screening Assessment Report on Vinyl Acetate (CASNo.108-05-4)" (PDF). Health Canada. 2009. If there is only one condition, i.e. /EX, it means that the item is not in a picture sleeve and that the disc is excellent. Records that aren't in picture sleeves will either be in a company sleeve or a generic plain sleeve. If you have any questions please get in touch.

It has a sweet, pleasant, fruity smell, but the odor may be sharp and irritating to some people.

It undergoes Diels-Alder reactions with dienes.

For the carbocation, see Vinyl cation. For other uses, see Vinyl. Chemical structure of the vinyl functional group. Vinyl groups can polymerize with the aid of a radical initiator or a catalyst, forming vinyl polymers. Vinyl polymers contain no vinyl groups. Instead they are saturated. The following table gives some examples of vinyl polymers.It can be polymerized to give polyvinyl acetate (PVAc). With other monomers it can be used to prepare various copolymers such as ethylene-vinyl acetate (EVA), vinyl acetate- acrylic acid (VA/AA), polyvinyl chloride acetate (PVCA), and polyvinylpyrrolidone (Vp/Va copolymer, used in hair gels). [8] Due to the instability of the radical, attempts to control the polymerization by most "living/controlled" radical processes have proved problematic. However, RAFT (or more specifically, MADIX) polymerization offers a convenient method of controlling the synthesis of PVA by the addition of a xanthate or a dithiocarbamate chain transfer agent.

POLYVINYLE 2 anagrammes plus une (Nouveaux mots formés avec toutes les lettres du mot plus une lettre.) 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. D. Swern & E. F. Jordan, Jr. (1963). "Vinyl Laurate and Other Vinyl Esters" (PDF). Organic Syntheses, Collected Volume. 4: 977.
