Abstract
The effect of addition agents on syneresis of silica gel is reviewed. Various methods of measurement of syneresis have been investigated and a convenient method that gave duplicate results agreeing within 1.2% is described. The effect of a series of alcohols—methyl, ethyl, glycol, glycerol, and erythritol—on syneresis has been studied. The results indicate that the total volume of syneretic liquid at equilibrium was the same as that of the control (within the experimental error) and that no adsorption had taken place in the gel itself. The data on the adsorption of the alcohols was determined by analysis of the syneretic liquid for its alcohol concentration by an oxidation method using chromic acid.
