Abstract:
The invention relates to a method for producing a biomass-resource-derived polyurethane, which comprises: reacting a dicarboxylic acid and an aliphatic diol to produce a polyester polyol; and reacting the polyester polyol and a polyisocyanate compound, wherein the dicarboxylic acid contains at least one component derived from biomass resources, a content of an organic acid in the dicarboxylic acid is more than 0 ppm and not more than 1,000 ppm relative to the dicarboxylic acid, and a pKa value of the organic acid at 25° C. is not more than 3.7.

Claim (Index 7):
The method for producing a biomass-resource-derived polyurethane according to  claim 1 , wherein the organic acid having a pKa value of the organic acid at 25\u00b0 C. of not more than 3.7 is at least one member selected from malic acid, tartaric acid, and citric acid.
