REACTIONS OF NH3 WITH POROUS GLASS SURFACES.
Abstract
Infrared spectra of NH3 sorbed on highly dehydroxylated, deuterated, and fluoridated porous glass were recorded. Two pairs of bands at 3409 and 3320/cm and at 3350 and 3308/cm were attributed to physically adsorbed NH3, hydrogen-bonded to the Si-OH and B-OH groups of the glass surface, resp. Bands at 3368 and 3282/cm were ascribed to a triple bond B:NH3 complex. Two pairs of bands at 3569 and 3479/cm and at 3543 and 3459/cm were ascribed to =B-NH2 and triple bond Si-NH2 groups, resp. A single band at 3455/cm was tentatively assigned to the N-H stretching vibration of a secondary amine, the nitrogen atom being bonded to two surface boron atoms. (Author)
