Abstract

Allyl halide is produced in high yields and purity with minimal carbon formation using a process of: (1) initially reacting propylene and molecular halogen in a molar ratio of at least about 2.5:1 in a 'continuously stirred tank reactor' (CSTR) zone under conditions suitable to provide a reaction temperature of about 400.degree. C. to 525.degree. C. to partially convert propylene and chlorine into allyl chloride; and (2) feeding an effluent from Step (1) into a plug-flow reactor zone where the reaction is continued at a temperature of about 400.degree. C. to 525.degree. C. until essentially all of the chlorine is consumed. A preferred reactor for the process contains: (1) a spherical, egg-shaped or oval reactor zone; (2) a tubular reactor zone attached to the spherical, egg-shaped or oval reactor zone; (3) one or more inlets for injecting gaseous reagents into the spherical, oval or egg-shaped reactor zone; and (4) one or more outlets from the tubular reactor zone for withdrawing a gaseous product.
