Atmospheric chemistry of unsaturated carbonyls: butenedial, 4-oxo-2- pentenal, 3-hexene-2,5-dione, maleic anhydride, 3H-furan-2-one, and 5-methyl-3H-furan-2-one

As part of a study on the oxidation mechanisms of aromatics some aspects of the atmospheric chemistry of several possible products, unsaturated 1,4-dicarbonyl compounds and two furanones, have been investigated in a 1080-L reaction chamber by 296 ± 2 K in 1000 mbar of synthetic air. The results indicate that reaction with OH radicals will be an important atmospheric sink for all of the unsaturated carbonyls studied here. However, for butenedial, 4-oxo-2-pentenal, and hexene-2,5-dione the results suggest that photolysis will probably be an even stronger sink. -from Authors
