α-Pinene is the main constituent of turpentine oil which can be derived to several valuable products. This paper studied heterogeneously-catalyzed liquid phase esterification of turpentine (79% α-pinene) with acetic acid. The catalytic experiments were carried out over various ion-exchange resins as solid acid catalysts. Reactions under atmospheric pressure and a temperature range of 45 – 90 oC were observed. Effect of α-pinene concentration in turpentine were investigated. Bornyl acetate was obtained to be the major esterification product. Small amount of fenchyl acetate and terpinyl acetate were detected. The reaction not only produced esterification products but also rearrangement products. The rearrangement products were mainly camphene, limonene, terpinene and terpinolene. It was found that purification of turpentine up to 88% α-pinene does not give significant difference to its original. Experiment shows that esterification of crude Indonesian turpentine over Amberlyst UP15 reached 100% conversion of α-pinene and 28.9% selectivity of bornyl acetate after 8 hours of reaction at 90oC. With the same condition, selectivity of bornyl acetate can achieved 26.2% when Amberlyst 36 wet is applied.
