Abstract

The ultrasonic velocity (u), density (ρ) and viscosity (η) of Fructose, Lactose and Sucrose in 0.4 M of Hydroxy Propyl Methyl Cellulose (HPMC) solutions have been investigated at 303, 313 and 323 K, respectively. The acoustical parameters such as adiabatic compressibility (β), intermolecular free length (Lf), internal pressure (πi), Rao’s constant (Ra), relaxation time (τ), acoustical impedance (Za), absorption coefficient (α/f2), free volume (Vf), cohesive energy (CE) and solvation number (Sn) have been computed. The non linear variations of acoustical parameters with concentration and temperature indicated the existence of strong molecular interaction in the systems studied. The FTIR spectroscopic analysis revealed the possibility of intermolecular hydrogen bonding in various saccharides.
