Industrial applications of organic polyiodides

Abstract

The major uses of iodine compounds are X-ray contrast media, disinfectants, pharmaceuticals, catalysts, and polarizers. Some of those applications are related to organic polyiodides. Polyiodides belong to the type of compounds known as hypervalent iodine, which violate the Lewis octet rule. This review summarizes various industrial applications of organic polyiodide compounds such as 1) Ion exchange resin (IER) iodine, Povidone (PVP) iodine, and Amylose iodine (disinfectants), 2) Polyvinyl alcohol (PVA) iodine and Bio-amylose iodine (polarizing film) and 3) Bio-amylose iodine (precursor of graphitic film).
