    Abstract: b -Chloroethane sulphochloride is prepared by reacting ethane, SO2 and Cl2 under the action of high-energy radiation and/or in the presence of substances forming free radicals and in the presence of an inert solvent, and then fractionally distilling the reaction mixture, at least 1 mole of SO2 and at least 2 moles of Cl2 being used for each mole of ethane. The solvent may be the reaction mixture obtained in a previous reaction. Hydrogen chloride gas may be passed in at the beginning of the reaction. In examples, CHCl2-CH3, CCl3-CH3, CHCl2-CH2Cl, CCl3-CH2Cl and C2H5SO2Cl are obtained as by-products. b -Chloroethane sulphochloride may be reacted with methanolic caustic soda solution to give methyl vinylsulphonate.
