Ultrasonic absorption and velocity have been measured in aqueous solution of Propyl Cellosolve (ethylene glycol monopropyl ether) in the frequency range of 7.5 to 220 MHz at 25 °C. A single relaxational process has been found and the mechanism has been attributed to the solute-solvent interaction, AB↔A+B. The rate constants obtained are <I>k</I><SUB>12</SUB>=9.6×10<SUP>7</SUP> s<SUP>−1</SUP> for the forward and <I>k</I><SUB>21</SUB>=1.3×10<SUP>8</SUP> M<SUP>−1</SUP> s<SUP>−1</SUP> for the backward reaction. The effect of the solute on the water structure has been found to act slightly as the water structure promoter and the results have been discussed comparing with those of Butyl Cellosolve solution.
