Interaction of butylamines with protonic centers of HNaY zeolite

IR-spectroscopic studies of the interaction of tert-, sec- and n-butylamine with HNaY protonic centers at 373–725 K and P_amine=0.13–13.3 kPa indicate that the deamination proceeds through intermediate butylammonium ions whose decomposition is the rate-determining step and can provide directly ammonium ions. The temperature of incipient reaction increases in the series: tert-
