Abstract The kinetics of camphene production in liquid phase from α-pinene was experimentally determinedin an isothermal batch reactor.To this end,a sulfated ZrO_2 catalyst was used and the reaction studied in thetemperature range of 370-403K.By analyzing the experimental data,second reaction order for α-pinene wasfound.A kinetic model is presented which includes term for the catalyst load used.The specific rate constant at393K was 2.19×10~(-3)mol.L~(-1),min~(-1),the activation energy being 93kJ.mol~(-1).Both Vaues are within the rangeof literature results.
