Abstract: A study of α-pinene hydration to produce α-terpineol has been carried out using macropore-strong acidic-cation exchange resin Lewatit2620 as the catalyst. Isomerizations of α-pinene take place simultaneously, changing into monocyclic terpene and effecting the yield of α-terpineol during the catalytic hydration reaction. Effects of variables such as types of catalyst, solvents, catalyst amount, mass ratio of reactants, temperature and reaction time in a stirred-tank reactor on the conversion of α-pinene and yield of α-terpineol were investigated systematically. The preferred reaction conditions were determined as the following: catalyst loading: 0.20 g catalyst / g total soluition, m(α-pinene)：m(water)：m(solvents:y) is 1：0.13：2, reaction temperature 333.1 K, reaction time 4 h.Under this condition, α-pinene hydration works efficiently. the conversion of α-pinene is 98% and yield of α-terpineol is 36%.The kinetics study is the basis of simulation, design, and amplification of industrial reactors, and is one of the main contents of chemical engineering. So the kinetics of the α-pinene hydration reaction has important significance. In this paper, a pseudo-homogeneous (PH) kinetic model was utilized to correlate the experimental data and estimated the kinetic parameters. The estimated kinetic parameters made the calculated results in excellent agreement with the experimental results, indicating that the PH model gives a good representation of the kinetic behavior for the direct hydration of turpentine. A pseudo first order model was used to explain the reaction rate equation
