This application discloses a method for preparing dihydroterpineol, relating to the field of terpene fragrance synthesis technology. The method comprises the following steps: Step 1, material preparation: α-terpineol, solvent, catalyst, hydrogen, and co-catalyst are prepared for use; Step 2, pretreatment: 90-100 parts of α-terpineol are mixed with 75-80 parts of solvent and stirred once until homogeneous, then 0.08-0.1 parts of co-catalyst are added and mixed again until homogeneous to obtain a stock solution; Step 3, continuous hydrogenation: The stock solution is pumped into a fixed-bed reactor filled with catalyst, while hydrogen is introduced and the temperature is controlled at 80-90℃ for continuous feeding and discharging to obtain a reaction solution; Step 4, distillation purification: The reaction solution is distilled to obtain dihydroterpineol; wherein the catalyst is a Pd-Mn-La / modified HZSM-5 catalyst. This application, by controlling the temperature at 80-90℃ for the preparation of dihydroterpineol, effectively improves product purity and yield, reduces preparation difficulty, and lowers production costs.
