Abstract
Abstract The gas-phase reaction of bornyl acetate (bicyclo[2,2,1]-heptan-2-ol-1,7,7-trimethyl-acetate), with hydroxyl radical has been studied. The rate constant determined at 294 K is k = (13.9 ± 2.2) × 10 −12 cm 3 .molecule −1 .s −1 1,7,7-trimethyl-bicyclo[2.2.1]-heptan-2-one; 4,7,7-trimethyl-5-acetyloxy-bicyclo[2.2.1]-heptan2-one and 1,7,7-trimethyl-6-acetyloxy-bicyclo[2.2.1]heptan-2,3-dione were identified as degradation products. Their estimated formation yields were lower than 1 %. The reaction of bornyl acetate with hydroxyl radical leads to organic aerosols. The fraction of the carbon initially present that is converted to aerosol remained under 5 %. 1,7,7 - trimethyl- 6 -acetyloxy-bicyclo[2.2.1]-heptan-2,3-dione has been identified as the main detected aerosol product.
