Abstract
This invention, in one respect, is a process for producing allylic chlorides which comprises contacting a feedstream containing an olefin in the gas phase with a chlorination composition under conditions effective to produce an allylic chlorine and wherein the mole ratio of oxygen to olefin is from 0 to about 1:20 in the feedstream. The chlorination composition contains supported palladium chloride, platinum chloride, or palladium chloride and a chloride of a Group 1 alkali metal selected from the group consisting of lithium, sodium, and potassium; a Group 2 alkaline earth metal; a Group 9 metal; nickel; and a Group 12 metal. The chlorination composition can be regenerated by contacting the chlorination composition with chlorine in a cyclic reaction scheme. In another respect, this invention is a composition consisting essentially of (A) palladium chloride, (B) a chloride of a metal selected from the group consisting of lithium, sodium, potassium, calcium, strontium, barium, nickel, and mixtures thereof, and (C) a support, wherein the weight percent of (A) and (B) in the composition is from about 0.1 to about 45.
