Polyester and polyurethane production method |
abstract |
The purpose of the present invention is to efficiently provide polyester having a good color tone, when producing polyester using a dicarboxylic acid component and a biomass resource-derived diol as the raw materials therefor. A biomass resource-derived raw material diol having a C5 or C6 cyclic carbonyl compound content of 0.01-12 ppm by mass is used. The color tone of the polyester is improved by controlling the C5 or C6 cyclic carbonyl compound content of the raw material diol to a prescribed range. |
