Density, viscosity and speed of sound of acetaminophen-propylene glycol solutions at 293.15 K temperature

Abstract

Physical and acoustical properties of drug - solvent mixtures are useful in the field of pharmaceutical sciences to examine their functions and performance. Measurements of physical properties: density, viscosity and ultrasonic velocities for the solutions of acetaminophen and propylene glycol at a constant temperature of 293.15 K were carried out. Precise density results are used to evaluate thermodynamic properties specific gravity (S G ), specific volume (S v ); for all solutions. Allied parameters of ultrasonic velocity for all solutions have also been evaluated. Results were analyzed to obtain some structural information of prepared drug - solvent mixtures and examined in view of their applicability in the field of pharmaceutical sciences.
