Abstract

A novel ionic liquid ([(C3H7)4N][B(CN)4]) was immobilized and coated by silicon in a ceramic nanofiltration module; this multiphase membrane shows a high selectivity (separation factor up to 177) and stability (over nine months) during separation of 1,3-propanediol from aqueous mixtures by vacuum pervaporation.
