- Structural Viscosity of Aluminum Stearates in Vegetable Oils
Description
The structural viscosity of aluminum stearate was measured in either sesame or peanut oil solution in the similar way observed in benzene solution, but the concentration, at which the structural viscosity appeared, was found to be higher than that of benzene solution. Concentration dependency of ηN (=ηr(1/Q→0)) in oil solution was weaker than that in benzene solution. Intrinsic viscosity [ηN] was much lower than that in benzene solution and there was not found such a sharp peak in the relation between [ηN] and St/Al ratio as observed in benzene solution. As to the result, it was considered that polymer chains of aluminum stearate were less extended in these oils than in benzene, or that polymer chains of aluminum stearate, especially of disoap, were broken either by a required heating for a preparation of oil solution, or by coordination of a certain component in the oil.<br>It was also found that structural viscosity, concentration dependency of ηN and intrinsic viscosity [ηN] were varied with the soap composition in oil solution, and these properties are observed most remarkably in disoap solution as compared with the other soap solutions.<br>In addition, no essential difference between sesame oil and peanut oil was observed.
