HYDRIODIC ACID • DICTIONARY ONE.COM • Definition of Hydriodic acid

... glacial acetic acid solution oxidizes it to chrysoquinone C18H10O2, which when distilled with lead oxide gives chrysoketone C17H10O. When chrysene is fused with alkalis, chrysenic acid, C17H12O3, is produced, which on heating gives [beta]-phenyl-naphthalene. On heating chrysene with hydriodic acid and red phosphorus to 260 deg.C, the hydro-derivatives C18H28 and C18H30 are produced. It gives characteristic addition products with picric acid and dinitroanthraquinone. Impure chrysene is of a yellow colour; hence its ...

... ether gradually absorbs oxygen from the atmosphere, being converted into acetic acid; this, by its superior affinities, reacts on the iodide present, converting it into acetate, with liberation of hydriodic acid; while this latter, under the influence of the atmospheric oxygen, is very rapidly converted into water ...
