Abstract
Vinyl chloride monomer is selectively prepared by intimately contacting, in the absence of steam, a feedstream of 1,2-dichloroethane with a flow of fluid or solid particulates heated to such elevated temperature and for such minim period of time, e.g., 0.010 to 0.5 second, as to flash transfer a dehydrochlorinating amount of thermal energy to the 1,2-dichloroethane and thereby ultrapyrolyzing at least a fraction of same into vinyl chloride and HCl, and recovering the vinyl chloride from the medium of ultrapyrolysis.
