STUDY OF N-BUTHANOL ADSORPTION ON THE SURFACE OF MODIFIED SILICA BY MEANS OF 13C NMR AND INFRARED SPECTROSCOPY
L.E. Kitaev, A.A. Kubasov, S.V. Malyishev (Division of Physical Chemistry) The adsorption of n-butyl alcohol on the surface of individual and modified with boron and 13 phosphorus compounds silica was investigated by means of C 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.
