Abstract

A study of the ultrasound enhancement of the acid hydrolysis of dextran was performed. Concentrations of HCl between 0.5 and 4.0 M and temperatures from 45 to 70 °C were examined in order to optimize the enhancements. The course of the reaction was followed by viscometry. The intrinsic viscosities were converted to molecular weights which were then fitted to the rate law Mt -a = M0 -a + kt. The activation energies for control and ultrasound reaction were 30.1 and 30.3 kcal, respectively. Ultrasonic enhancements up to 36% were observed. © 1984, American Chemical Society.
