Abstract: cf. C.A. 45, 5559i. After elimination of disturbing secondary reactions, a new polarometric method for direct titration by Br soln. in nonaq. CH3COOH was developed. To det. the end point, a combination of polarometric and potentiometric methods was used. A new chloranil reference electrode was prepd. and its behavior during the reduction-oxidation titrations in nonaq. CH3COOH was studied. By this method the following compds. were detd.: cyclohexene, dicyclopentadiene, elaidic acid, ricinoleic acid, erucic acid, styrene, limonene, camphene, terpineol, pinene, sabinene, sabinol, cinnamyl alc., castor, olive and rape oil, essential oils of citronella, rosemary, peppermint, thyme, and eucalyptus, balsam of copaiba, resins of elemi, fir, and gum guttae, and the Et ester of linolic acid. The purity and the I nos. were in agreement with the results of this method.
