The study of the modification of silica gels by various organotitanium compounds (OTC) is of interest in connection with their possible use as specific adsorbents, catalysts in the preparation of filled polymeric materials. The authors studied the modification of silica gel by OTC of different types in order to obtain reactive functional organic groups bound to titanium atoms on its surface. During treatment of silica gel with organotitanium compounds of different types in an organic solvent, these react chemically with the hydroxylic groups of silica gel to form Si-O-Ti groups on the surface, containing organic radicals bound to the titanium atom. In the case of coordinatively unsaturated OTC, increase in the time of interaction of the components on heating and excess OTC lead to partial splitting of the Si-O-Ti bonds, which is not observed for coordinatively saturated OTC.
