The infrared spectra ot twenty amine bydroohlorides were obtained with the Perkin-Elmer Model 21 recording spectrophotometer. The positions of the absorption bands were compared with literature values for pertinent structural group frequencies. A system of coding the spectral data was devised so that an IBM 1620 digital computer could make the comparisons for a large number of' group frequencies. Good agreement was observed between the positions of the absorption bands in the experimental spectra and those of pertinent group frequencies reported in the literature.
Of the ten symmetrical diamines which were studied, six contained the primary hydroxyl group. Two similar compounds without this group, 2, 8-dimethyl-3,7-diazee-5-nonanol dihydrochloride and 2, 2, 8, 8-Tetramethyl-3, 7-diaza-5-nonanol dihydrochloride, were synthesized. These two were not found in the literature.
When the compounds were purified by recrystallization, many or them ware highly hygroscopic and required special techniques to remove moisture before taking the spectra.
