✦ Synopsis

A =ETI-IOD has been developed by which anthraquinone may be determined quantitatively in mixtures containing also phenanthraquinone, anthracene, phenanthrene, phthalic anhydride, phthalic acid, or other oxidation products of anthracene or phenanthrene. It consists essentially in reducing the anthraquinone to the red oxanthranol, using zinc powder and 5 per cent. solution of sodium hydroxide. The red solution is filtered in vacuum and titrated with standard potassium permanganate.
