History
In 1835, Vinyl chloride (CAS NO.75-01-4) was first produced by Justus von Liebig and his student Henri Victor Regnault. They obtained it by treating ethylene dichloride with a solution of potassium hydroxide in ethanol.
In 1912, Frans, a German chemist working for Griesheim-Elektron, patented a means to produce vinyl chloride from acetylene and hydrogen chloride using mercuric chloride as a catalyst. Whereas this method was widely used during the 1930s and 1940s, it has since been superseded by more economical processes, at least in the West.

Specification
The Vinyl chloride, with the CAS registry number 75-01-4 and EINECS registry number 200-831-0, has the systematic name of chloroethene. And the molecular formula of this chemical is C2H3Cl. It is a kind of colourless gas with a sickly sweet odor, and also called VCM which is shourt for vinyl chloride monomer.
The physical properties of Vinyl chloride are as following: (1)ACD/LogP: 1.69; (2)ACD/LogD (pH 5.5): 1.69; (3)ACD/LogD (pH 7.4): 1.69; (4)ACD/BCF (pH 5.5): 11.33; (5)ACD/BCF (pH 7.4): 11.33; (6)ACD/KOC (pH 5.5): 197.82; (7)ACD/KOC (pH 7.4): 197.82; (8)Index of Refraction: 1.384; (9)Molar Refractivity: 15.889 cm3; (10)Molar Volume: 68.027 cm3; (11)Polarizability: 6.299 10-24cm3; (12)Surface Tension: 17.5160007476807 dyne/cm; (13)Density: 0.919 g/cm3; (14)Flash Point: -55.958 °C; (15)Enthalpy of Vaporization: 23.039 kJ/mol; (16)Boiling Point: -10.545 °C at 760 mmHg; (17)Vapour Pressure: 2579.74291992188 mmHg at 25°C
Preparation of Vinyl chloride: It mainly prepared by two methods, the hydrochlorination of acetylene and the dehydrochlorination of ethylene dichloride (1,2-dichloroethane). And the production of vinyl chloride from 1,2-dichloroethane (EDC) consists of a series of well-defined steps. EDC is prepared by reacting ethylene and chlorine. In the presence of iron(III) chloride as a catalyst, these compounds react exothermically: CH2=CH2 + Cl2→ ClCH2CH2Cl
Uses of Vinyl chloride: It is a chemical intermediate, and often used to produce polyvinyl chloride. And it is used as an inhalational anaesthetic, in a similar vein to ethyl chloride, though its toxicity forced this practice to be abandoned. In addition, it is also used as an aerosol propellant and is the starting material for polyvinyl resins.
You should be cautious while dealing with this chemical. It is a kind of extremely flammable chemical, and has danger of very serious irreversible effects through inhalation, in contact with skin and if swallowed. What's more, it may also cause cancer. Therefore, you had better take the following instructions: Wear suitable protective clothing and gloves; Avoid exposure - obtain special instruction before use; In case of accident or if you feel unwell, seek medical advice immediately (show label where possible).
You can still convert the following datas into molecular structure:
