Studies in inorgano-organic gels in pinene. Part III. Viscosity measurements of gel-forming solutions of sodium oleate and sodium stearate in pinene

Abstract

Viscosity measurements during the sol-gel transformation of gel-forming solutions of sodium oleate and sodium stearate in pinene have been made using two types of viscometers. Results obtained with the Ostwald type of viscometer follow the Einstein equation within a certain range of temperature. The regularities observed in the viscosity-time data obtained by the Falling Sphere viscometer during the sol-gel transformation of soap-pinene systems can be conveniently expressed by the empirical relation η-η₀=ae^kt . The viscosity data has been employed for the purpose of drawing inferences regarding the mechanism of sol-gel transformation of soap-pinene systems.
