Abstract:
Halogen chemistry plays a central role in the industrial manufacture of
various important chemicals, pharmaceuticals, and polymers. It involves the reaction of
halogens or halides with hydrocarbons, leading to intermediate compounds which are
readily converted to valuable commodities. These transformations, predominantly
mediated by heterogeneous catalysts, have long been successfully applied in the
production of polymers. Recent discoveries of abundant conventional and unconven-
tional natural gas reserves have revitalized strong interest in these processes as the most
cost-effective gas-to-liquid technologies. This review provides an in-depth analysis of the
fundamental understanding and applied relevance of halogen chemistry in polymer
industries (polyvinyl chloride, polyurethanes, and polycarbonates) and in the activation
of light hydrocarbons. The reactions of particular interest include halogenation and
oxyhalogenation of alkanes and alkenes, dehydrogenation of alkanes, conversion of alkyl
halides, and oxidation of hydrogen halides, with emphasis on the catalyst, reactor, and
process design. Perspectives on the challenges and directions for future development in
this exciting field are provided.
