ABSTRACT:
An improved process for the production of silicon dioxide ion exchangers, which comprises the step of reacting silicon dioxide with benzyltrichlorosilane, in the absence of solvent and air, followed by hydrolysis, to produce a benzylated silicon dioxide whose benzyl groups can then be substituted with ion exchange reactive groups in a conventional manner.
