Molecular Interactions of Pyridoxine Hydrochloride in Aqueous Mixed Solutions of D-Glucose, D-Fructose, and D-Lactose at Different Temperatures

详细

Density and ultrasonic velocity values for solutions of pyridoxine hydrochloride in aqueous mixed solutions containing D-glucose, D-fructose, and D-lactose have been obtained for various concentrations and at temperatures 298.15–313.15 K. Volumetric and acoustic parameters such as partial molar volumes, partial molar adiabatic compressibilities, partial molar expansibilities were determined using density and ultrasonic velocity data. The analysis of the obtained data has been done by using Masson’s equation and interpretation was done in terms of solute–solute and solute–solvent interactions. The pyridoxine hydrochloride acts as a structure breaker in water as well as in binary aqueous mixed solutions of D-glucose, D‑fructose, and D-lactose.
