Ir spectra of preparations of ozonized pyrocatechin

Journal of Applied Spectroscopy Aims and scope

Abstract

We investigate IR spectra of the solid phase of products obtained at different stages in the process of ozonizing aqueous solutions of pyrocatechin. We found that melanin structures are formed in the process of pyrocatechin ozonization. The existence of intra- and intermolecular interactions in the melanin preparations formed, leading to the formation of molecular associates, is shown. Thorough treatment of preparations with ozone leads to destruction of polymer systems and formation of water-soluble products of acid type.
