Atmospheric Oxidation of N-Methyl Succinimide Initiated by OH Radicals: A Theoretical Study

We are happy to announce that Dr. Ngo Son Tung and colleagues recently published their work entitled “Atmospheric Oxidation of N-Methyl Succinimide Initiated by OH Radicals: A Theoretical Study ”  in the Journal of Atmospheric Chemistry.

Abstract:

A study of the oxidation mechanism of N-methyl pyrrolidinone (C₅H₉NO, NMP) initiated by hydroxyl radicals was made at EUPHORE at atmospheric pressure (1000 ± 10) mbar of air and ambient temperature (T = 300 ± 5 K). The main products were N-methyl succinimide (NMS) (52 ± 4)% and N-formyl pyrrolidinone (FP) (23 ± 9)%. The relative rate technique was used to determine the rate constants of OH with NMP, NMS and FP, the measured values were (in units of cm³ molecule ^{− 1} s^{− 1}): k_NMP = (2.2 ± 0.4) × 10^{− 11}, k_NMS = (1.4 ± 0.3) × 10^{− 12} and k_FP = (6 ± 1) × 10^{− 12}. The results are presented and discussed in terms of the atmospheric impact.
