摘　　要：The kinetics of camphene production in liquid phase from α-pinene was experimentally determined in an isothermal batch reactor. To this end, a sulfated ZrO2 catalyst was used and the reaction studied in the temperature range of 370-403 K. By analyzing the experimental data, second reaction order for α-pinene was found. A kinetic model is presented which includes term for the catalyst load used. The specific rate constant at 393K was 2.19×10^-3 mol·L^-1·min^-1, the activation energy being 93kJ·mo1·^-1. Both values are within the range of literature results.The kinetics of camphene production in liquid phase from α-pinene was experimentally determined in an isothermal batch reactor.
