Abstract

1,213,202. Vinyl chloride; 1,2-dichloroethane. LUMMUS CO. 5 Feb., 1968 [6 Feb., 1967], No. 5718/68. Heading C2C. [Also in Division B1] Vinyl chloride is produced by passing (a) ethane, ethylene or a mixture thereof, and (b) chlorine, hydrogen chloride or a mixture thereof, into a first reaction zone in which is a melt containing at least one chloride of a multivalent metal and the oxychloride of that metal to produce a gaseous effluent containing vinyl chloride and 1,2-dichloroethane, withdrawing the gaseous effluent from the first reaction zone and separately recovering vinyl chloride and 1,2-dichloroethane as products therefrom, contacting the recovered 1,2-dichloroethane with a catalyst comprising a melt containing a chloride of the said metal in a second reaction zone wherein 1,2-dichloroethane is dehydrochlorinated to produce on effluent containing vinyl chloride, and separating vinyl chloride as product therefrom. The hot melt from the first reaction zone, containing the chloride of the metal in its lower valency state, is passed to the second reaction zone wherein it is cooled by the dehydrochlorination reaction. The melt withdrawn from the second reaction zone may be passed to a third reaction zone wherein it is contacted with a gas containing molecular oxygen to produce a melt containing the metal oxychloride, which regenerated melt is recycled to the first reaction zone. The multivalent metal is preferably copper. The melt may contain other metal chlorides which are non-volatile and oxygen-resistant so as to lower the melting point, e.g. alkali metal chlorides such as KCl and LiCl, and heavy metal chlorides such as ZnCl 2 , AgCl and thallium chloride. Ethane, ethylene and hydrogen chloride may be recycled to the first reaction zone. Ethyl chloride, 1,1-dichloroethane, trichloroethanes, tetrachloroethanes, dichloroethylenes, trichloroethylene and tetrachloroethylene are formed as by-products. Ethyl chloride and the vinyl chloride free effluent from the second reaction zone may be recycled to the first reaction zone. The gaseous effluents from the first and second reaction zones may be provided separately or be combined prior to separation of the vinyl chloride.
