The Determination of Eucalyptol by Residual Titration With Hydrogen Bromide in Acetic Acid*

Abstract

Eucalyptol is determined by treating samples with an excess of hydrogen bromide reagent. After a forty-eight-hour standing period, excess hydrogen bromide is titrated with sodium acetate in acetic acid. Mixtures of eucalyptol with thymol, menthol, and camphor are analyzed for eucalyptol content. Quantitative recoveries are reported.
