Abstract The paper reports the discovery of a new homogeneous gas phase reaction in which methanol converts S03 to SOe. In the course of this reaction NO is converted to NOe. This new reaction is highly selective in that ppm concentrations of S03 and NO are converted by quantities of methanol only slightly greater than stiochiometry in the presence of massive amounts of De. Both the conversion of S03 to SOe and of NO to NOe are resevrsible in that at. any given temperature there is an optimum reaction time and use of reaction times longer than this optimum causes decreasing conversion. For optimum temperature the reaction is also rapid, capable of achieving better than BOY. reduction in only 55 milliseconds. The existence of this new reaction was predicted by computer modeling. Subsequent experiments were in reasonably good accord with the model's predictions. The mechanism by which methanol similanteously reduces S03 and oxidizes NO involves methanol functioning as a source of HOe free radicals which then undergo the reactions NO+HOe=NOe+OH, S03+HOe=HS03+Oe , and HS03+M=SOe+OH.
