Beta Pinene Website

The main objective of the extraction process is to obtain crude sulphate turpentine from wood chips. Heating is conducted to the wood chips then separate the existing black liquor and fibers in the water and turpentine by a separator. Next, the black liquor is flashed to obtain water and turpentine vapor. The vapor mixture is further condensed and the aqueous and turpentine phases are separated due to density differences. The product obtained in the turpentine phase is crude sulphate turpentine which will be distilled to obtain beta-pinene.

Beta pinene is the favorable product from the distillation of crude turpentine. By boiling point differences, the heating is conducted to separate impurities that have lower boiling points from the crude turpentine. Once the impurity is off, the vacuum is intensified. Due to the difference in volatility between alpha and beta-pinene, the exact reflux ratio is applied to obtain separated beta-pinene from the mixture, thus beta-pinene recovered is high in purity.
