Effects of composition and temperature on viscosity, ultrasound velocity, and refractive index of propiophenone-benzyl acetate binary mixtures at 303.15-323.15 K

Liquid density, viscosity, ultrasonic velocity and refractive index values have been reported for the binary system of propiophenone and benzyl acetate at temperatures 303.15-313.15 K for the whole compositions. Equations have been developed for the effect of temperature and concentration on viscosity, ultrasonic velocity and refractive index. The nature of molecular interaction has been concluded from the excess properties as well as from the newly developed equations.
