Abstract

The influence of power ultrasound (20kHz) on the rate of attainment of saturation of sparingly soluble benzoic acid in distilled water and in 24% (w/w) aqueous glycerol was experimentally investigated at 30 degrees C. The importance of proper temperature control of process vessel contents when it was irradiated with high ultrasonic power level settings was demonstrated. A method was proposed to calculate the volumetric mass transfer coefficient under non-isothermal conditions.
