dc.description.abstractDilute mixtures of n-heptanal in synthetic air (up to 100 ppm) were photolyzed with fluorescent UV lamps (275-380 nm) at 298 K. The main photooxidation products, identified and quantitatively analyzed by FTIR spectroscopy, were pent-1-ene, CO, vinyl alcohol and ethanal. The photolysis rates and the absolute quantum yields φ were found to be slightly dependent on the total pressure. At 100 Torr, φ100 = 0.36±0.03, whereas at 700 Torr the total quantum yield was φ700 = 0.31± 0.01. The results may be explained by the collisional deactivation of photoexcited molecules. Two decomposition channels were identified: the radical channel C6H13CHO → C6H13 + HCO, and the molecular channel C6H13CHO → C5H10 + CH2=CHOH, having the absolute quantum yields of 0.031 and 0.118 at 700 Torr. The product CH2 = CHOH tautomerizes to ethanal.sr
