Physicochemical Properties of Chlorine Oxides. 1. Composition, Ultraviolet Spectrum, and Kinetics of the Thermolysis of Gaseous Dichlorine Hexoxide

The experimental evidence presented here shows that gaseous dichlorine hexoxide at room temperatures has essentially the composition Cl2O6 and not ClO3 as currently accepted.Vapor pressure measurements of liquid Cl2O6 between 5 and 45 deg C have been made.The absorption cross section values of gaseous Cl2O6 are approximately 3 times higher than those assigned to ClO3 by other authers.The products of the thermal decomposition of gaseous Cl2O6 are mainly chlorine perchlorate and oxygen.The kinetics of the decomposition over the Cl2O6 pressure range 0.5-1.2 Torr,at 20 - 30 deg C, follows a first order rate equation and is independentof the total pressure.A unimolecular process, namely, Cl2O6 - Cl2O4 + O2, proceeding at the high-pressure limit through a complex fission reaction is postulated.The rate constant kinfinite = 1011.4+/-1.2) exps-1 is determined.

Properties of dichlorine hexaoxide in the gas phase and in low-temperature matrices

The IR spectrum of matrix-isqlated dichlorine hexaoxide shows that there are two inequivalent chlorine atoms in the molecule and that it is best described as the mixed anhydride of chloric and perchloric acids. Of 18 fundamental vibrations, 16 were observed and many of them were assigned. O3ClOClO2 exhibits a broad UV absorption at 268 nm (εmax = 3000 dm3 mol-1 cm-1) in the gas phase. It is decomposed on photolysis in an Ar matrix to ClOClO3 and O2. The kinetics of formation and decomposition of O3ClOClO2 in the gas phase were also investigated. The rate of formation depends strongly on the concentration of ClO2 and O3. Cl2O6 does not dissociate into ClO3 radicals, and the primary stable decomposition products are ClO2, ClOClO3, and O2.
