Syneresis of sodium oleate gels in organic solvents

Part II. Effect of time on the syneresis of sodium oleate gels in pinene and xylene

The effect of time on the syneresis of sodium oleate gels in pinene and xylene has been investigated. The graphs of synereticum against time are smooth rising curves and are not S-shaped as is the case with silica gels. The rate of syneresis is large in the initial period and falls off continuously with time. The progress of syneresis does not follow the law of first order reaction observed in the case of geranin gels. The plots of log X against logt for the gels in both the solvents give, in each case, a pair of intersecting straight lines indicating the existence of two different processes of syneresis. An explanation has been advanced for this behaviour.
