Abstract: High purity butanol can be manufactured by means of the disclosed butanol manufacturing method which comprises: a manufacturing step (A) wherein a butanol-containing solution is filtered by being passed through a nano-filtration membrane, and the butanol-containing solution is collected from the permeation side; a manufacturing step (B) wherein the butanol-containing solution obtained in step (A) is concentrated by being passed through a reverse osmosis membrane, and separated into two phases, namely a butanol phase and a water phase; and a manufacturing step (C) wherein butanol is collected from the butanol phase obtained in step (B).

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: 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.
