The kinetics of camphene production in liquid phase from a-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, a second reaction order for a-pinene was found. A kinetic model is presented which includes term for the catalyst load used. The specific rate constant at 393 K was 2.19 x 10-3 l mol-1 min-1, the activation energy being 93 KJ mol-1. Both values are within the range of literature results.
