Summary:A method for producing a polyol, the method including: (a) reacting at least one selected from the group consisting of an unsaturated natural fat, an unsaturated natural fatty acid, and a fatty acid ester with dinitrogen monoxide, to obtain a first intermediate; (b) reacting the first intermediate with a hydrogenation reagent, to obtain a second intermediate; (c) reacting the second intermediate with at least one alkylene oxide, to obtain a polyol.
