Study of n-Buthanol
Adsorption on the Surface of Modified Silica by Means of 13C NMR and Infrared
Spectroscopy
Abstract
The adsorption of n-butyl
alcohol on the surface of individual and modified with boron and phosphorus compounds
silica was investigated by means of 13C NMR and
IR spectroscopy. The modified samples reproduce acidic centers of
boronphosphate or zeolites, which structure contains either boron or phosphorus
atoms. It has been shown that the interaction of alcohol functional group with
proton donor and especially electron acceptor centers was predominant.
Nonspecific interaction of methylene group with oxygen atoms of PO4 took
place when adsorbed n-butanol molecule had flat orientation on adsorbent
surface.
