PROCESS OF PRODUCING 1,4-BUTANEDIOL |
摘要 |
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. |
