Abstract

The experimental data of ultrasonic velocity, density, viscosity has been obtained for some thiosemicarbazide and thiaoxadizenes at different temperature in 70% and 75% DMF over the conc. range of (0.002 to 0.01) mol Kg-1. The derived parameters such as apparent molar volume of solute (Фv), limiting apparent molar volume of solute (Ф0v), limiting apparent molar expansivity (Ф0E), thermal expansion coefficient (α*) and Jones-Dole viscosity coefficient were obtained using the density and viscosity results. The variations of these properties with concentration give the information about solute-solvent interactions.
