Abstract
The reaction of the periodate–permanganate reagent with olefinic double bonds was applied to the determination of isopropylidene groups. The oxidation of compounds containing such groups gave a quantitative yield of acetone which could be readily determined by known iodometric and colorimetric procedures. Use of aqueous solutions of pyridine or dioxane as solvent permitted analysis of water-insoluble compounds. The colorimetric determination of acetone was then preferred. This method also allowed a simultaneous estimation of terminal methylene groups. The content of isopropylidene groups of commercial samples of three terpenes of the geraniol type was determined.Keywords
