摘要: A method for producing a diol or triol, which has a step of removing impurities contained in a diol- or triol-containing solution, is provided. In the method, a diol- or triol-containing solution is filtered through a nanofiltration membrane having a polyamide-containing functional layer. The diol- or triol-containing solution is then collected from the permeate flow of the nanofiltration membrane.

摘要: 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.

摘要: 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.
