Specification

The CAS registry number of Vinyl acetate is 108-05-4. The IUPAC name is ethenyl acetate. In addition, the molecular formula is C₄H₆O₂. What's more, it is a colorless liquid with a pungent odor. And it is the precursor to polyvinyl acetate. It can be polymerized, either by itself to make polyvinyl acetate or with other monomers to prepare copolymers such as ethylene-vinyl acetate.

Physical properties about this chemical are: (1)ACD/LogP: 0.63; (2)ACD/LogD (pH 5.5): 0.629; (3)ACD/LogD (pH 7.4): 0.629; (4)ACD/BCF (pH 5.5): 1.77; (5)ACD/BCF (pH 7.4): 1.77; (6)ACD/KOC (pH 5.5): 52.382; (7)ACD/KOC (pH 7.4): 52.382; (8)#H bond acceptors: 2; (9)#Freely Rotating Bonds: 2; (10)Polar Surface Area: 26.3 Å²; (11)Index of Refraction: 1.39; (12)Molar Refractivity: 22.081 cm³; (13)Molar Volume: 93.138 cm³; (14)Polarizability: 8.753 ×10^-24cm³; (15)Surface Tension: 23.482 dyne/cm; (16)Density: 0.924 g/cm³; (17)Flash Point: °C; (18)Enthalpy of Vaporization: 31.389 kJ/mol; (19)Boiling Point: 72.499 °C at 760 mmHg; (20)Vapour Pressure: 118.484 mmHg at 25°C.

Preparation of Vinyl acetate: the major industrial route involves the reaction of ethylene and acetic acid with oxygen in the presence of a palladium catalyst. The reaction temperature is 160-180 °C and the reaction pressure is below 1MPa. The equation is as follows: 2CH₂=CH₂ + 2CH₃CO₂H + O₂ → 2CH₂=CHOCOCH₃. In addition, acetylene can react with acetic acid in the presence of zinc amalgam to give this chemical. The equation is as follows: CH≡CH + CH₃CO₂H → CH₂=CHOCOCH₃.

Uses of Vinyl acetate: it is mainly used for organic synthesis. In addition, it can react with 1-phenyl-ethanol to get (R)-1-acetoxy-1-phenyl-ethane. This reaction will need reagents Pseudomonas fluorescens Lipase, o-phenantroline and acetophenone, catalyst Rh₂(OAc)₄ and solvent CH₂Cl₂. The reaction time is 72 hours at reaction temperature of 20 °C. The yield is about 60%.

Vinyl acetate can react with 1-phenyl-ethanol to get (R)-1-acetoxy-1-phenyl-ethane

When you are using this chemical, please be cautious about it as the following:
This chemical is highly flammable. And it has danger of very serious irreversible effects through inhalation, in contact with skin and if swallowed. During using it, wear suitable protective clothing, gloves and eye/face protection. You can not breathe gas/fumes/vapor/spray (appropriate wording to be specified by the manufacturer). And in case of accident or if you feel unwell, seek medical advice immediately (show label where possible). What's more, you should keep away from sources of ignition and no smoking. In addition, you should not empty into drains. Keep container tightly closed after using it. Besides, you can take precautionary measures against static discharges.

You can still convert the following datas into molecular structure:
(1)SMILES: CC(=O)OC=C
(2)InChI: InChI=1/C4H6O2/c1-3-6-4(2)5/h3H,1H2,2H3
(3)InChIKey: XTXRWKRVRITETP-UHFFFAOYAB
