THE VARIATION OF RELATIVE VISCOSITY WITH TEMPERATURE ORGANIC SOLUTES IN NON-AQUEOUS SOLVENTS

A fairly comprehensive study of the temperature dependence of relative viscosity (\(\eta_s/\eta_o\)) of concentrated and supersaturated solutions of non-electrolytes in non-aqueous solvents has been made. The observed valves of \(\delta/\delta_1\) (\({\delta_s \over \delta_o}\)) can be divided into three categories, viz., (i) having approximately zero variation. (ii) having positive value, and (iii) having negative value for the variation of relative viscosity. In majority of casts the results can be explained by Rabinovich's solvate hypothesis and the depolymerisation hypothesis of Applebey
