SEPPORTED IONIC LIQUID MEMBRANE FOR RECOVERY OF BUTANOL FROM REAL FERMENTATION BROTH AND PREPARATION METHOD THEREOF

摘要

PURPOSE: A separating membrane for collecting butanol from a fermented liquid and a manufacturing method of the same are provided to improve the collecting rate for butanol and to improve the selectivity of a separating membrane with respect to butanol. CONSTITUTION: A separating membrane for collecting butanol from a fermented liquid is composed of a porous support and an ionic liquid in the porous support. The ionic liquid is represented by chemical formula 1. The porous support has nanopores or micropores. The porous support is one selected from a group including mono-layered polypropylene, polysulfone, and polyvinylidene fluoride. The fermented liquid is a biomass which is fermented by microorganisms. The microorganisms are solventogenic clostridia strains.
