Abstract: Procedimiento para producir butanol, comprendiendo dicho procedimiento: Etapa A, en la que una solución que contiene butanol obtenida mediante fermentación microbiana se filtra a través de una membrana de nanofiltración y una solución que contiene butanol se recupera del lado del permeado; Etapa B, en la que dicha solución que contiene butanol obtenida en la etapa A se hace pasar a través de una membrana de ósmosis inversa y un concentrado que contiene butanol se recupera del lado de la alimentación, en la que la concentración se lleva a cabo de una manera tal que la concentración de butanol en el concentrado no sea menor que el 8% en peso; y se permite que el agua permee en el lado del permeado; Etapa C, el concentrado que contiene butanol obtenido en la etapa B, que se ha sometido a una separación de dos fases, se separa en una fase de butanol y una fase acuosa; y Etapa D, en la que el butanol se recupera de dicha fase de butanol obtenida en la etapa C.

Abstract: Provided is a method for producing a sugar liquid using a cellulose-containing biomass as the starting material. Sugar liquid having a very low fermentation-inhibiting substance content is produced by a method comprising (1) a step in which a cellulose-containing biomass is hydrolyzed to produce an aqueous sugar solution and (2) a step in which the resulting aqueous sugar solution is filtered through a nanofiltration membrane and/or reverse osmosis membrane, the pure sugar liquid is recovered from the unpermeated side, and the fermentation-inhibiting matter is removed from the permeated side.

Abstract: In the present invention, a sugar alcohol can be efficiently produced from a cellulose-containing biomass by carrying out a step (1) of filtering an aqueous sugar solution, which is obtained by hydrolysis of a cellulose-containing biomass, by passing the solution through a separation membrane having a molecular cut-off of 300-800 so as to remove catalyst poisons to the non-permeate side and collecting a sugar solution from the permeate side, and a step (2) of subjecting the sugar solution obtained in step (1) to a hydrogenation reaction in the presence of a metal catalyst.

Abstract: By a method for producing a diamine comprising the step of purifying a diamine from an aqueous solution containing a diamine salt, the method comprising a step of adding an alkaline substance to the aqueous solution and then filtering the resulting solution by allowing the solution to pass through a nanofiltration membrane to remove the salt, thereby obtaining an aqueous diamine solution, a diamine suitable as a raw material for a polyamide can be obtained by a simpler operation than by a conventional extraction operation with an organic solvent.

Abstract: Provided is a polyester with an excellent color tone, and improved molding stability and mechanical properties. This improvement is achieved by controlling the electrical conductivity of the diol composition, which is a raw material for the polyester, to be between 0.6 mS/m and 30 mS/m, and preferably by controlling the pH of the diol composition to be between 5 and 7.5, thereby reducing the heating weight loss ratio of the polyester.

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.
