Mechanism and kinetic study on the gas-phase reactions of OH radical with carbamate insecticide isoprocarb

► OH radicals are more easily added to aromatic ring than to CO bond. ► The rate constant of the MIPC with OH is about 5.1 × 10−12 cm3 molecule−l s−l. ► The OH addition reactions decreases with the temperature increasing. ► The H abstraction reactions increases with the temperature increasing.
