The photooxidation of allyl chloride

The photooxidation of allyl chloride was studied by irradiation either in 100‐L Teflon bags or in a 22.7‐m 3 Teflon smog chamber in the presence of added NO x . In the absence of added hydrocarbons, the reaction involves a Cl atom chain, which leads to a highly reactive system. A reaction mechanism is presented to account for the following photooxidation products: chloroacetaldehyde, formaldehyde, 1,3‐dichloroacetone, 3‐chloroacrolein, acrolein, glyoxal, chloroperoxyacetyl nitrate, and peroxypropenyl nitrate. The rate constant for OH reaction with allyl chloride at 298 K was measured by a relative rate method under conditions where the Cl atom chain length was small and was found to be k OH = 1.7 × 10 −11 cm 3 molecule −1 s −1 . The rate constant for O 3 reaction with allylchloride at 298 K was found to be k O3 = 1.5 × 10 −18 cm 3 molecule −1 s −1 .
