Preparation and Characterization of Terpene-Based Diol from Terpene-Maleic Anhydride Using Lithium Aluminum Hydride as Reductant
A Diol with endocyclic structure that is 1-methyl-4-isopropyl-bicyclo [2,2,-2,3-two hydroxymethyl-5-Octene (MIBHO), deriving from terpene, was synthesized using the aid of lithium aluminium hydride (LAH) as reductant in THF media at 65 °C. The optimum synthesis conditions were confirmed by analysing the factors on reacting temperature, reacting time, different solvents and reductants. The molecular structure of the novel compound has been characterized by FT-IRGC-MS and 1H-NMR analysis. The data reveal that LAH could effectively reduce terpene maleic anhydride to corresponding alcohol, and the conversion rate of raw material could reach 84%.
