Method of obtaining allyl chloride and reactor therefor

摘要

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 2.5:1 in a "continuously stirred tank reactor" (CSTR) zone under conditions suitable to provide a reaction temperature of 400 DEG C to 525 DEG 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 400 DEG C to 525 DEG 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 (1); (2) a tubular reactor zone (2) attached to the spherical, egg-shaped or oval reactor zone (1); (3) one or more inlets (3,4) for injecting gaseous reagents into the spherical, oval or egg-shaped reactor zone (1); and (4) one or more outlets (5) from the tubular reactor zone (2) for withdrawing a gaseous product.
