Procedure
Another aspect of this invention is a method of preheating chemical reaction vessels prior to start of operations of an exothermic reaction so that the reactor can be heated from ambient conditions to the temperature at which the exothermic reaction can be initiated and maintained during operation. Preferably, there is provided a chemical reaction vessel having at least two heating assemblies as described hereinabove which are switched to the on position for reactor preheat of about 2000 amps and 10-15 volts and left until the temperature reaches that desired. Then the heating assemblies are switched off and the reactor feed is allowed to enter the feed inlet and upon contacting the hot environment of the reactor the desired reaction occurs and the products and byproducts, if any, are allowed to leave via the crude product outlet. Typical examples of such processes are carried out in thermal chlorinators which produce methyl chloride, methylene chloride, trichloromethane, perchloroethylene, trichloroethylene, allyl chloride and the like.
