Oxidative chlorination of hydrocarbons. Part 2. Oxidative chlorination of propylene, 1,3-butadiene, acetylene and benzene

The review paper considers main regularities of the oxidative chlorination of some unsaturated hydrocarbons: propylene, acetylene, butadiene-1,3 and benzene. It was shown that the implementation of such processes in the gas phase requires the presence of heterogeneous catalysts based on copper or palladium in the system. Depending on the process conditions, the products of additive or substitutive chlorination are formed. Kinetic equations and probable conversion mechanisms were proposed for the oxidative chlorination of propylene, acetylene and benzene. Prospects of the practical implementation of the oxidative chlorination of some unsaturated hydrocarbons were considered.
