摘　　要：The kinetics of non-catalyzed pinacol rearrangement in high temperature liquid water was investigated at 10 MPa and temperature from 180℃ to 220℃. Rate constants were evaluated with the first-order reaction assumption. The activation energy evaluated was 176.4 kJ·mol -1 . The experimental results demonstrate that non-catalyzed pinacol rearrangement in high temperature liquid water is possible with high pinacol conversion and pinacolone yield over 80%.The kinetics of non catalyzed pinacol rearrangement in high temperature liquid water was investigated at 10 MPa and temperature from 180℃ to 220℃.
