Abstract
Intrinsic viscosity of a mixture of aluminum-distearate and either aluminum-monostearate or stearic acid was measured in benzene. By the addition of a small quantity of either monosoap or stearic acid to disoap, [ηN] decreased suddenly similar to that of the synthesized soaps, which were reported in a previous paper, but the values of [ηN] were found higher than that of synthesized one. The actions of monosoap and stearic acid to the disoap were compared with those of ethyl alcohol, octadecyl alcohol, p-toluidine and acetic acid. Each of additives was heated with aluminum-distearate in benzene, and the viscosity of this solution was measured at various concentrations of the additives in different heating period. Monosoap and alcohol made the viscosity lower monotonously, as the concentration of the additives was increased and heating period of time was lengthened. With stearic acid, the viscosity was increased at a low concentration in a short period of heating time, but it decreased with an increase of the concentration and the heating period of time. Monosoap and stearic acid, similar to the other additives, were found to depolymerize disoap polymer by the coordination. An increase of viscosity by the addition of stearic acid was considered to explaine by the formation of disoap from monosoap and stearic acid and by the coordinate bond between two oxygen atoms of stearic acid and two aluminum atoms and hence the chain was made longer.
