Atmospheric Pressure Chemical Ionization Negative Mass Spectra of the Dinitrotoluene Isomers.
Abstract
The atmospheric pressure chemical ionization of the dinitrotoluene (DNT) isomers in ambient air was studied with a quadrupole mass spectrometer operating in the negative mode. The isomers can be grouped on the basis of the product ions: the 2,5-, the 2,6-, and the 3,5-DNT give the molecular anion with little fragmentation; the 2,3- and the 3,4-DNT behave similarly but with more extensive fragmentation; the 2,4-DNT gives the quasimolecular (DNT-H)- with little fragmentation. The results are discussed in terms of the molecular structure of the isomers. (Author)
