Abstract

Mass spectra of octaethylporphyrines of cobalt, nickel, copper with electron ionization were obtained. Molecular ions with isotope peaks and the peaks formed by separation hydrogen atoms from porhyrins core have maximum intensity. Appearance energies of some ions from OEP copper and its ionization energy have been determined. Electron ionization mass spectra at temperature up to 4000C and mass spectra at energies of ionizing electrons from 70 to 20 eV have been obtained for OEP copper. Ionization energy of OEP copper is 6.8±0.2 eV. It was concluded that OEP of copper, nickel, and cobalt in the gas phase are stable at least until 3000C.
