Popis: The reaction of TiCl4 with the surface of a silica gel has been investigated in detail using Fourier-transform IR photoacoustic spectroscopy (FTIR PAS) and elemental analysis. The hydroxy groups on the silica react with the TiCl4 giving rise to both monodentate and didentate surface groups. The parameters influencing the relative distribution of these groups have been studied. A quantitative description of the chemisorbed species has been obtained as a function of the pretreatment and the reaction temperatures.
