Abstract: The hydration reaction catalyzed by the ion-exchange resin, was used to reduce the content of caryophyllene in the heavy turpentine and get the longifolene of high purity. Effects of temperature, time and any other factors were investigated. The results showed, under a suitable conditions, the content of caryophyllene will be as low as 1.1%, the conversion of caryophyllene will exceed 90%.

Key words: heavy turpentine, longifolene, β-caryophyllene, hydration, ion-exchange resin
