Abstract
The reaction mechanism of (CH3)2CHONO2 with X(X=Cl, OH and NO3 radical) was studied at M06-2X/ 6-311++G(d, p) level of theory, and the energy of the stationary points was calculated by CCSD(T) method. The kinetics of the reaction was calculated by the conventional transition state theory. The hydrogen bonded complexes are formed firstly by isopropyl nitrate and X radical, and X radical can abstract the α-H or β-H atoms from (CH3)2CHONO2. The α-H abstraction is the main channel, and the main products are (CH3)2CO + NO2 + HCl(H2O or HNO3). The yield of α-H abstraction products decreases as the temperature increases from 200 K to 500 K for IPN + OH reaction. The overall rate constant for the reaction of (CH3)2CHONO2 with Cl atom, OH and NO3 radical at 300 K is 3.933×10-11, 1.182×10-13, and 7.134×10-19 cm3·molecule-1·s-1, respectively. The theoretical kinetics data is in consistent with the previous experimental values for the reaction of OH with isopropyl nitrate.
