Abstract
A dried silica gel containing a reagent in insolubilized form which reagent is normally soluble, especially a dried silica gel containing an insolubilized form of a normally soluble colorimetric analytical agent and a method of preparing such dried silica gel by hydrolyzing a silane having from 1 to 4 alkoxy groups in a homogeneous phase in the presence of a reagent which is normally soluble in a solvent, recovering the resultant gel and drying the same.
Claims11
A process for preparing a dried silica gel containing insolubilized reactive form a reagent which is normally soluble which comprises hydrolyzing a silane having from 1 to 4 alkoxy groups in homogeneous phase in the presence of a soluble reagent, recovering the resultant silica gel and drying the same.
