Heterogeneous reaction of nitric acid with methyl sulfide

Abstract

. J. Chem. 63, 2805 (1 985).The reaction of gaseous mixtures of CH3SCH3 and HNO,, studied by infrared spectroscopy and gas chromatography, was found to occur heterogeneously. The products detected were NO2 and CH3S(0)CH3, and approximately one NOz was formed for each CH,SCH, consumed. The initial rate of formation of NOz was first order in CHsSCH, and zero order in HNO,. The mechanism is discussed, and an upper limit is determined for the rate constant of the homogeneous reaction.
