Kinetic studies of xenon trioxide as an oxidant-I Determination of alcohols.
A kinetic study of the oxidation of some alcohols by xenon trioxide has revealed the optimum conditions for analysis of these alcohols. The rate of reaction may be increased by adding a catalyst or by increasing the pH of the solution; it may be decreased by adding an inhibitor. The initiation time of the reaction is used to determine t-butanol in amounts as low as 22 mug or 880 parts per milliard (ppM). Primary and secondary alcohols which catalyse the reaction between t-butanol and xenon trioxide may be determined in amounts as low as 2.3 mug or 92 ppM. Tertiary butanol in amounts less than 40mug is determined with a coefficient of variation of 4% while methanol, ethanol and isopropanol are determined with a coefficient of variation of 10% at the level of 25mug or more. The precision in determination of t-butanol increases with increasing concentration, while for isopropanol, ethanol and methanol it decreases.
