In chemistry, alcohols are organic compounds that carry at least one hydroxyl functional group (C–OH) bound to their aliphatic substructure. The term alcohol originally referred to the primary alcohol ethanol (ethyl alcohol), which is used as a drug and is the main alcohol present in alcoholic beverages. An important class of alcohols, of which methanol and ethanol are the simplest members, includes all compounds for which the general formula is CₙH₂ₙ₊₁OH. Simple monoalcohols that are the subject of this article include primary (RCH₂OH), secondary (R₂CHOH), and tertiary (R₃COH) alcohols.

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.
