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: The present invention is a method for producing e-caprolactam via adipamide that serves as an intermediate. This method for producing e-caprolactam is characterized by comprising a lactamization step wherein adipamide produced from a starting material compound is reacted with hydrogen and ammonia in the presence of a catalyst which contains a metal and/or a metal compound having hydrogenation ability and a metal oxide that mainly contains an oxide of one or more metal elements selected from the group consisting of metal elements of the fourth to sixth rows in groups 5, 7 to 14 of the periodic table. This method is capable of enhancing the selectivity of e-caprolactam.

Abstract: A method of producing butanol, which has a step of removing impurities contained in a butanol-containing solution, is provided. In the method, a butanol--containing solution is filtered through a nanofiltration membrane. Then the butanol-containing solution is collected from the permeate flow of the nanofiltration membrane.

Abstract: A sugar liquid containing only very small amounts of fermentation-inhibiting substances is produced by a method for producing a sugar liquid using a cellulose-containing biomass as a raw material, the method comprising: (1) a step of hydrolyzing a cellulose-containing biomass to produce an aqueous sugar solution; and (2) a step of filtering the obtained aqueous sugar solution through a nanofiltration membrane and/or reverse osmosis membrane to collect a purified sugar liquid from the feed side, while removing fermentation-inhibiting substances from the permeate side.
