Abstract

Rate coefficients for the reactions of hydroxyl radicals and chlorine atoms with a series of halogenated acetones of the type CX3COCH3 (X= H, Cl, F) have been determined using a photolytic relative-rate technique at T= 298 K and at 760 Torr total pressure. The reactions studied and the rate coefficients obtained are shown in the table. Reaction Reaction number Rate coefficient/cm3 molecule− 1 s− 1 OH+ CH3COCH3→ products (1)(2.2±0.5)× 10− 13 ...
