Abstract
IN an extension of kinetic studies of the catalytic decompositions of hydrocarbons, infra-red spectra of ammonia chemisorbed upon silica–alumina catalysts have been obtained. The techniques employed were similar to those described previously by Eischens et al. 1. A Perkins–Elmer model 112 C infra-red spectrometer utilizing calcium fluoride and lithium fluoride optics was modified by mounting the glowbar source in a position above the infra-red cell housing the catalyst deposit held in a horizontal manner.
