It is found that the 1414 cm 1 infrared feature due to the symmetric oco stretching mode of the acetate species decreases. The reaction pathway of vinyl acetate synthesis is scrutinized by reacting gas phase ethylene at an effective pressure of 1 10 4 torr with η2 acetate species with a coverage of 0 31 0 02 monolayer on a pd 111 o 2 2 model catalyst surface in ultrahigh vacuum.

Please select more than one item to compare. Vinyl acetate is the acetate ester of vinyl alcohol. The major industrial route involves the reaction of ethylene and acetic acid with oxygen in the presence of a palladium catalyst. 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.

L acétate de vinyle est préparé en règle générale en phase vapeur en faisant réagir un grand excès d acétylène sur de l acide acétique 200 c en présence de catalyseurs au zinc et au cadmium on obtient un liquide incolore à odeur très pénétrante qui ne se polymérise en polyacétate de vinyle pvac qu en présence de catalyseurs et donne des solides durs.
