The invention relates to a preparation method of soybean oil base polyhydric alcohol, in particular to a method for preparing soybean oil base polyhydric alcohol by directly using soybean oil. The soybean oil diluted by using a solvent reacts with hydrogen peroxide with the weight percentage being 30% for 2-5 hours at the temperature of 60-70 DEG C under catalysis of a catalyst with the weight percentage being 3-5%; vacuum distillation is conducted after the reaction is ended, and the solvent is evaporated; then low alcohol is added in a reactor to be subjected to a reaction for 4-6 hours under the pressure of 0.3-0.4 MPa and at the temperature of 70-80 DEG C, then the reaction is stopped, and the soybean oil base polyhydric alcohol is obtained. The method saves the using amount of hydrogen peroxide, reduces the post-treatment steps, and simplifies the production procedures, and accordingly the product cost is declined directly.
