Study on the Reaction Characteristics of Directional Synthesis of α-Terpineol from Turpentine

There was rarely high-purity alpha-terpineol or pure-monomer alpha-terpineol in China due to difficulty in isolating alpha-terpineol and gamma-terpineol. Aiming at the separation problem, alpha-terpineol was directional synthesized by one-step method in a uniform system. The influence factors of stereochemistry structure, thermodynamic analysis and stability of reactants, products and carbocations were researched, conducting the experiments in optimal reaction conditions. All the influence factors about generating trend of objective product alpha-terpineol and byproduct gamma-terpineol were discussed and the reaction mechanism was studied. This paper provided certain theoretical basis on prepare high-purity alpha-terpineol.
