The high resolution double focusing mass spectrometer of reversed Nier-Johnson geometry was used in research of ionization and fragmentation processes of ethanol molecules C_2H_5OH. Using the mass-analyzed ion kinetic energy technique, fragmentation paths and kinetic energy release distributions were examined for the four fragmentation reactions: C_2H_6O^{+} → C_2H_5O^{+}, C_2H_6O^{+} → C_2H_3O^{+}, CH_3O^{+} → CH_2O^{+} and CH_3O^{+} → CHO^{+}. For all fragment ions from these reactions mean values of kinetic energy release 〈ε〉 were determined. We calculated mean values of 〈ε〉 as 22.70 meV, 62.15 meV, 30.25 meV, and 117.20 meV for C_2H_5O^{+}, C_2H_3O^{+}, CH_2O^{+}, and for CHO^{+} ions, respectively.
