Reaction of carbon monoxide with sulphur dioxide

3 Reaction of carbon monoxide with sulphur dioxide 

The only study of the thermal reaction between CO and SO2 has been performed in a shock tube by Bauer et al. [506] using the single pulse technique with a mixture of CO and SO2 heavily diluted with argon, over the temperature range 1770—2453 K. Reflected shock residence times were 370—540 psec. No SjO, SO3 or O2 were found in the reaction products, and only traces of COS and CS2 were generated. The principal product was CO2, of which two moles were formed per mole of SO2 which disappeared. Although not precisely established, the stoichiometry is close to 

To obtain the observed partial orders for each reactant, the reactions postulated were 

However, the data are not sufficient to exclude other possibilities.
