A Spectrophotometric Study of the Interaction of Aromatic and Aliphatic Iodine-Containing Substances with Dimethyl Sulphoxide

The electronic absorption spectra of solutions of aromatic and aliphatic iodine-containing substances in dimethyl sulfoxide, which are components of adhesive compounds for blood vessels, have been studied. It has been shown that, during storage of iodinated fatty acids, iodine is split off from them with the formation of an ion, with the presence of dimethyl sulfoxide and KI accelerating this process. Within 25 days, the concentration of bound iodine in solutions of iodinated fatty acids decreased three times. The stability of solutions of iodinated aromatic substances in dimethyl sulfoxide during storage for at least 6 months has been shown.
