Furanic Molecules: Multiplexed Synchrotron Photoionization Investigations and Aerosol Studies

<p> The oxidation reactions of 2-methylfuran (2MF) and 2-ethylfuran (2EF) initiated by Cl radicals is studied at the low temperatures, in addition to the determination of the absolute photoionization cross-sections of 2EF, 2-acetylfuran, and furfural. These experiments are carried out using synchrotron photoionization mass spectrometry (SPIMS) with an orthogonal time-of-flight spectrometer used for mass analysis at the Advanced Light Source of Lawrence Berkeley National Laboratory. CBS-QB3 calculated adiabatic ionization energies (AIE) agree well with the experimental results and published literature values. Furfural is found to be the dominant product of 2MF oxidation, with 2-acetylfuran and 2-vinylfuran being the dominant products of the 2EF oxidation reaction. Additional experiments are employed to observe how 2MF would act as an aerosol in the atmosphere.</p>
