Abstract
An object of the present invention is to provide high-quality 1,4BG capable of working out to a raw material of PBT with good color tone, by efficiently removing and refining impurities mixed when producing a biomass-derived 1,4BG on an industrial scale and the present invention relates to a production method of refined 1,4BG, where a crude 1,4BG-containing solution is obtained from refined raw material 1,4BG obtained by removing bacterial cells, salt contents and water from the fermentation culture medium, through a step of removing high-boiling-point components and/or low-boiling-point components by distillation and/or a step of converting an unsaturated compound to a hydride and the target product is obtained as a side stream in a further distillation step.
