✦ Synopsis

The nitric acid formed from rmfirs-2-butene. propene, ethene, toluene. and rr-butane in single hydr~c~jrb~~n/NO~/purified air systems was examined in smog chamber experiments. The effect of hydrocarbon and NO, concentrations on the maximum HNO, yieid. defined as percentages of initial NO, converted to HNO;, was studied in two sets of experiments. In every hydrocarbon system. we found no effect of hydrocarbon concentration variation on the nitric acid formed. Out of initially added IO0 pph NO:. in the hydrocarbon-rich systems, ethene formed most HNO, (45%), followed by propene, toluene, and tl-butane (24%). and IY~FL--7-hutene (13%). When the initial NO, concentration was varied with a constant hydr(~c~irbon c~~ncent~lti~)n, the am~~unt of HNO, formed was found to linearly increase with the added NO, down to ~HC~~~NO~~ ratios, which depended on the nature of the hydrocarbon studied. The initial rate of HNO, formation in hydrocarbon excess experiments varied between SO. 35, 2.3, 16, and X pph/hr for hutcne. propene. toluene, ethene. and hutanc systems. respectively.
