| Abstract: | We have carried out laboratory measurements of gas-phase ion-molecule-reactions of several negative ion species with propionic, butyric, glyoxylic, pyruvic, and pinonic acids. A flow reactor operating at a temperature of 293 ± 3 K and total gas pressures of 1.5 hPa, 9 hPa, or 40 hPa were used. The negative reagent ion species investigated included CO3−, CO3−H2O, NO3−, NO3−H2O, NO2−, NO2−H2O, and O3−. The reactions were found to proceed either via proton transfer, switching, or clustering. A new proton transfer channel leading to alkylperoxy carboxylate radicals (R−H(OO·)COO−) was observed for propionic, butyric, and pinonic acids. |
