Abstract: A process produces 1,4-butanediol by purifying 1,4-butanediol originated from a fermentation broth, by which process 1,4-butanediol having properties suited as a material of producing a polyester is obtained, which 1,4-butanediol enables to reduce by-production of tetrahydrofuran during the esterification reaction and to reduce the delay in polymerization. The process of producing 1,4-butanediol includes adding an alkaline substance other than an ammonia or an amine to an aqueous 1,4-butanediol-containing solution originated from a fermentation broth; distilling the resulting mixture; and recovering a 1,4-butanediol- containing solution from the vapor flow.
Abstract translation: 一种方法是通过纯化发酵液中的1,4-丁二醇来纯化生产1,4-丁二醇的方法，通过该方法可得到具有适合作为生产聚酯材料的性能的1,4-丁二醇，该1,4-丁二醇可使 在酯化反应期间减少四氢呋喃的副产物并减少聚合的延迟。 生产1,4-丁二醇的方法包括将不同于氨或胺的碱性物质加入到发酵液中的含1,4-丁二醇的水溶液中; 蒸馏所得混合物; 并从蒸气流中回收含有1,4-丁二醇的溶液。
