Benzonitrile ions, decomposition

Ion lifetimes from nanoseconds down to microseconds have been determined in experiments involving ionization within the confines of a molecular beam and decomposition within a strong electric field [381, 667, 672]. Using electron impact ionization, rates of decomposition have been determined as a function of time over the range 3 ns to 1 p s for ions formed from butane, heptane, perdeuteromethane, benzene, carbon dioxide and benzonitrile. [Pg.88]

Jones and Paisley have reported the ionic and thermal fragmentation of 4,6-diphenyl-l,2,3,5-oxathiadiazine-2,2-dioxide, 26. Thermal decomposition of 26 in the solid state leads to formation of benzonitrile and a brown-colored intractable glass. The major ionic decomposition pathways for 26 are shown in Eq. (17). The failure of 26 to eliminate SO 2 on thermolysis lysis may reflect a heteroatom effect it may also be due to a medium effect with the SO 2 being trapped before it could escape the solid. It should be noted that the only volatile pyrolysis product, benzonitrile, appears as an intense ion, mfe 103, in the mass spectrum of 26. [Pg.109]
