Abstract
The present invention provides an efficient process for the production of ethylene or a mixture of ethylene and vinyl chloride, in which some 1,2-dichloroethane (EDC) may also be produced, by reacting chlorine with ethane. The process is characterized by a conversion of ethane per pass through the reactor of at least about 50%, and a combined molar yield of ethylene and vinyl chloride of at least about 80% based on the ethane consumed. In accordance with this invention, there is provided a process for preparing ethylene or a mixture of ethylene and vinyl chloride by the reaction of ethane and chlorine which comprises: PA1 (a) providing a stream of ethane feed gas and a stream of chlorine feed gas; PA1 (b) preheating either said ethane stream only or both said ethane and chlorine streams; PA1 (c) thoroughly mixing said ethane and chlorine feed gases within about one second and at a molar ratio of ethane to chlorine of at least about 0.9:1.0; PA1 (d) said preheating being sufficient to enable the resultant mixture to have a temperature above the free radical formation temperature for chlorine; and PA1 (e) permitting said ethane and chlorine in said mixture to react so that the reacte…
