发明名称 PRODUCTION METHODS OF POLYESTER AND POLYURETHANE
摘要 At the time of producing a polyester by using a dicarboxylic acid component and a biomass-resource-derived diol as raw materials, a polyester is efficiently produced with good color tone, as the raw material diol derived from biomass resources, a diol in which the content of a cyclic carbonyl compound having a carbon atom number of 5 or 6 is from 0.01 to 12 ppm by mass, is used, and by controlling the content of a cyclic carbonyl compound having a carbon atom number of 5 or 6 in the raw material diol to fall in a prescribed range, the color tone of the polyester is improved.

主权项 1. A method for producing a polyester, comprising: performing reaction by using, as raw materials, a dicarboxylic acid component and a diol produced directly from a biomass-resource-derived substance by a fermentation process, wherein a content of a cyclic carbonyl compound having a carbon atom number of 5 or 6 in the diol is 12 ppm by mass or less.
