Allyl acetate (AA) is widely used as monomer and intermediate in industrial chemicals synthesis. To evaluate the atmospheric outcome of AA, kinetics and mechanism of its gas-phase reaction with main atmospheric oxidants (O3, OH, Cl, and NO3) have been investigated in a Teflon reactor at 298 ± 3 K. Both absolute and relative rate methods were used to determine the rate constants for AA reactions with the four atmospheric oxidants. The obtained rate constants (in units of cm3 molecule-1 s-1) are (1.8 ± 0.3) × 10-18, (3.1 ± 0.7) × 10-11, (2.5 ± 0.5) × 10-10, and (1.1 ± 0.4) × 10-14, for reactions with O3, OH, Cl, and NO3, respectively. While results for reactions with O3, OH and Cl are in good agreement with previous studies, the kinetics for the reaction with NO3 is reported for the first time in this study. On the basis of determined rate constants, the tropospheric lifetimes of AA are ρO3 = 9 days, ρOH = 5 h, ρCl = 5 days, ρNO3 = 2 days. On the basis of the products study, reaction mechanisms for these oxidations have been proposed and the reaction products were detected using thermal desorption-gas chromatography-mass spectrometry (TD-GC-MS) and Fourier transform infrared spectroscopy (FTIR). Results show that the main products formed in these reactions are carbonyl compounds. In particular, 2-oxoethyl acetate was detected in all four AA oxidation reactions. Compared to previous studies, several new products were determined for reactions with OH and Cl. These results form a set of comprehensive kinetic data for AA reactions with main atmospheric oxidants and provide a better understanding of the degradation and atmospheric outcome of unsaturated acetate esters in the troposphere, during both daytime and nighttime.

A potential source of acetates, including allyl acetate, is combustion of esterified rape oil used as substitution fuel. This new formulation of diesel fuel significantly reduces the emission of particulate matter. To better evaluate the environmental impact of acetates, OH-induced oxidation kinetic and mechanism of allyl acetate were studied at room temperature and 1 atm using three environmental chambers (an indoor Teflon-film bag, an indoor Pyrex photoreactor, and the outdoor smog chamber EUPHORE. The main oxidation products were acetoxyacetaldehyde and formaldehyde. A mechanism was developed to describe the OH-induced oxidation of the acetate in the presence of NOx. Reaction with OH radicals was the main tropospheric fate of allyl acetate. When it reacted with OH radicals, it could contribute to the formation of photooxidants close to the emission sources. Acetoxyacetaldehyde yield was slightly smaller in the experiment at low NOx since some peroxides could be produced from peroxy radical + HO2 reaction and compete with the acetoxyacetaldehyde production.

The synthesis of the reactive acetates, trans-3-acetoxy-2-hydroxy-N-nitrosomorpholine 3 and N-(1-acetoxy-2-hydroxyethyl)-N-nitrosoethanolamine 12, of two α-hydroxynitrosamines has been accomplished through the ring opening of the corresponding epoxides, NEMOR and 10 which were prepared by dimethyldioxirane oxidation of the vinyl nitrosamines.
