Abstract
A study ofα-pinene hydration to produceα-terpineol has been carried out using macropore-strong acidic-cation exchange resin Lewatit2620 as the catalyst.Isomerizations ofα-pinene take place simultaneously,changing into monocyclic terpene and effecting the yield ofα-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 ofα-pinene and yield ofα-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 ofα-pinene is 98% and yield ofα-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 theα-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 ex-perimental results,indicating that the PH model gives a good representation of the kinetic behavior for the direct hy-dration of turpentine.A pseudo first order model was used to explain the reaction rate equation.关键词
