9,9′-Bis(fluorenylidene) and Tetra-n-heptylammonium Iodide for the Measurement of Ozone Concentrations in Organic Media
The two title compounds were shown to be useful reagents for determination of ozone and peroxides in organic media and at temperatures as low as -78°C. 9,9′-Bis(fluorenylidene) is a highly colored hydrocarbon whose quantitative disappearance upon reaction with ozone can be followed spectrophotometrically. Tetra-n-heptylammonium iodide, a nonhygroscopic organic-soluble iodide, reacts quantitatively with ozone and peroxidic materials yielding iodine, which can be measured by the usual methods. Reaction and measurement conditions for both systems were also studied.
