Abstract: BUTANOL MANUFACTURING METHODHighly 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 IC 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: The present invention relates to a method for producing lactate, the method comprising a step of crystallizing an aqueous lactate solution containing formate in a ratio of at least 7.0 wt% relative to the lactate, and recovering the lactate. Crystallizing the aqueous lactate solution containing formate in a ratio of at least 7.0 wt% relative to the lactate makes it possible to stabilize the supersaturation of the lactate, and makes it possible to improve the recovery rate of the lactate.

Abstract: Disclosed is a process for producing a diamine, comprising the step of purifying a diamine from an aqueous solution containing a diamine salt. Specifically, the process comprises the step of adding an alkaline substance to the aqueous solution and then filtering the aqueous solution through a nanofiltration film to remove the salt and thus to obtain an aqueous diamine solution, whereby a diamine suitable as a starting material for a polyamide can be obtained by a simpler operation than a conventional extraction operation with an organic solvent.
