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

There was rarely high-purity α-terpineol or pure-monomer α-terpineol in China due to difficulty in isolating α-terpineol and γ-terpineol. Aiming at the separation problem, α-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 α-terpineol and byproduct γ-terpineol were discussed and the reaction mechanism was studied. This paper provided certain theoretical basis on prepare high-purity α-terpineol.
