Abstract

Linalool ozone reactions were conducted in two stainless steel chambers (3.4 and 150ft3) and the gas and particle phase chemistry has been studied. A preliminary analysis of the gas and particle phase products have been performed and a number of intermediates including 2-ethenyl-2-methyl-5- hydroxytetrahydrofuran, 2(3H)-furanone-5-ethenyldihydro-5-methyl-, tetrahydro-1-methyl-5-oxo2-furancarboxylic acid and 2-hydroxy-2,3- dimethylsuccinic acid have been identified. The particle size distributions of the secondary organic aerosols (SOA) produced due to these reactions has been obtained. Yield of the products in the SOA has also been obtained to study the partition of organics produced in the gas and particle phase. Further, reactive oxygen species (ROS) have been identified as produced during the reaction process. Fluorescence techniques have been employed in identifying and quantifying these species in the sub-micron SOA. It was concluded that the concentration of linalool and ozone play a vital role in the formation and growth of SOA.
