Abstract: An alcohol production method whereby high quality alcohol can be easily and effectively produced includes a step in which an alcohol solution, which contains sugar and/or sugar alcohol as an impurity and an alcohol other than sugar alcohol as a main component, has the sugar and/or sugar alcohol adsorptively removed therefrom by contacting the alcohol solution with one type or a mixture of two or more types of adsorbents selected from zeolite, an ion-exchange resin, silica alumina, and alumina.

Abstract: Highly pure butanol can be produced by a method for producing butanol, the method comprising: Step A, wherein a butanol-containing solution is filtered through a nanofiltration membrane and a butanol-containing solution is recovered from the permeate side; Step B, wherein the butanol-containing solution obtained in Step A is passed through a reverse osmosis membrane and thereby concentrated to cause two-phase separation into a butanol phase and an aqueous phase; and Step C, wherein butanol is recovered from the butanol phase obtained in Step B.

Abstract: A method for selective production of µ-caprolactam, wherein a substance inducible from a biomass resource is used as a material; the reaction process is short; ammonium sulfate is not produced as a by-product; and production of by-products is suppressed; is disclosed. The method for producing µ-caprolactam comprises the step of reacting a particular compound inducible from a biomass resource, such as ±-hydromuconic acid, 3-hydroxyadipic acid, or 3-hydroxyadipic acid-3,6-lactone, or a salt thereof with hydrogen or ammonia.

Abstract: By subjecting a 2,3-butanediol culture liquid produced by microbial fermentation to nanofiltration membrane treatment and ion-exchange treatment (Step A), and then adding an alkaline substance and performing distillation (Step B), 2,3-butanediol having a high purity and remarkably low degree of pigmentation can be obtained.

Abstract: By controlling the electrical conductivity of a diol composition, a polyester material, at 0.6 mS/m to 30 mS/m, and, preferably, controlling the pH of the diol composition at 5 to 7.5, the thermal weight loss rate of a polyester is reduced, and, consequently, a polyester with improved mechanical properties and molding stability as well as excellent color tone is provided.

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.
