Density Functional Investigation of Some Decomposition Routes of Methyl Nitrate.
Abstract
Two density functional methods, B3/LYP/6-31+G(d) and B3/PW91/6-31G(d,p) have been used to investigate some possible decomposition pathways for methyl nitrate. Two likely ones were found to be (a) loss of NO2, followed by eventual rearrangement to H2C-OH, and (b) formation of H2C=O and HONO. The initial energy requirement for each process is about 40 kcal/mole, and the second is exothermic, delta H = -16 kcal/mole of H3CO-NO2. The B3/LYP procedure is found to underestimate the H3CO-NO2 and H3C-ONO2 dissociation energies by about 7 kcal/mole.
