摘要：

Novel modified catalyst carriers have been prepared. First, aminopropyltriethoxysilane (APTES) was immobilized on the silica surface by using the saturated gas-solid reactions. Secondly, two different (tetramethylcyclopentadienyl)chlorosilanes (Me2Si(C5Me4H)Cl and MeHSi(C5Me4H)Cl), were synthesized and anchored on the amine surface using liquid-phase reactions. Characterization of these stepwise prepared surfaces was carried out by H-1, C-13 and Si-29 solid state NMR and FTIR spectroscopy. (C) 1999 Elsevier Science B.V. All rights reserved.
