Chloroethene Vinyl chloride

Chlorination of various hydrocarbon feedstocks produces many usehil chlorinated solvents, intermediates, and chemical products. The chlorinated derivatives provide a primary method of upgrading the value of industrial chlorine. The principal chlorinated hydrocarbons produced industrially include chloromethane (methyl chloride), dichloromethane (methylene chloride), trichloromethane (chloroform), tetrachloromethane (carbon tetrachloride), chloroethene (vinyl chloride monomer, VCM), 1,1-dichloroethene (vinylidene chloride), 1,1,2-trichloroethene (trichloroethylene), 1,1,2,2-tetrachloroethene (perchloroethylene), mono- and dichloroben2enes, 1,1,1-trichloroethane (methyl chloroform), 1,1,2-trichloroethane, and 1,2-dichloroethane (ethylene dichloride [540-59-0], EDC).

For trichloroethene (TCE), the stoichiometric amount of iron and the effect of different preparations determine the outcome of the several competing reactions. Coupling products such as butenes, acetylene and its reduction products ethene and ethane, and products with five or six carbon atoms were formed (Liu et al. 2005). Although a held-scale application successfully lowered the concentration of TCE, there was evidence for the formation of the undesirable di-l,2-dichloroethene and 1-chloroethene (vinyl chloride) in the groundwater (Quinn et al. 2005).

The aerobic degradation of chloroethene (vinyl chloride) by Mycobacterium aurum strain LI proceeded by initial formation of an epoxide mediated by an alkene monooxygenase (Hartmans and de Bout 1992). This reaction has also been demonstrated to occur with Methylosinus trichosporium, even though subsequent reactions were purely chemical (Castro et al. 1992b).

Illustrative Example 5.1 Deriving Liquid Aqueous Solubilities, Aqueous Activity Coefficients, and Excess Free Energies in Aqueous Solution from Experimental Solubility Data Problem Calculate the Cf (L), yf 1 and G of (a) di-n-butyl phthalate, (b) y-1,2,3,4,5,6-hexachlorocyclohexane (y-HCH, lindane), and (c) chloroethene (vinyl chloride) at 25 °C using the data provided in Appendix C. 

Chloroethene (vinyl chloride) is a gas at the temperature considered. Hence, the enthalpy of solution (Awa//,) is given by the sum of the enthalpy of condensation (AcmiHi, which is equal to the negative enthalpy of vaporization) and the excess enthalpy in aqueous solution (Hi) (Fig. 5.1 and Eq. 5-26). Horvath et al. (1982) gives the solubilities of chloroethene at 0°C, 25°C, and 50°C and 1 bar partial pressure. Also given are the vapor pressures of the superheated liquid at these three temperatures.
