Ozone in Polar (Acetonitrile) and Nonpolar (Carbon Tetrachloride) Organic Liquids: Optical Absorption, Solubility, and Stability

The optical characteristics, solubility, and decomposition kinetics of ozone in polar (acetonitrile, CH3CN) and nonpolar (carbon tetrachloride, CCl4) liquids in the temperature range 233.15–295.15 K were studied. The rate constants of the O3 decomposition at 295.15 K in CH3CN and CCl4 are 3.3×10−5 a...

Description
Summary:The optical characteristics, solubility, and decomposition kinetics of ozone in polar (acetonitrile, CH3CN) and nonpolar (carbon tetrachloride, CCl4) liquids in the temperature range 233.15–295.15 K were studied. The rate constants of the O3 decomposition at 295.15 K in CH3CN and CCl4 are 3.3×10−5 and 5.0×10−5 s−1, respectively. At low temperatures, ozone solutions are practically stable. The solubility coefficients at 295.15 K are 2.6 in CH3CN and 2.9 in CCl4; at 233.15 K, they increase to approximately 7.0. Thus, these two liquids have a set of properties making them optimum for studying the ozonolysis in polar and nonpolar media. Acetonitrile and carbon tetrachloride are optimal media for the oxidation of organic substances of different polarity with ozone at temperatures from about 243 K and above. Ozone solutions are practically stable for several dozens of minutes. High concentrations can be measured by the absorption of ozone in the visible region.
