Abstract
Continuous separation of organic compounds is possible by selective transport through a supported liquid membrane, which contains the room-temperature ionic liquid 1-n-butyl-3-methylimidazolium hexafluorophosphate immobilized in the porous structure of a hydrophilic polyvinylidene fluoride membrane. A mixture (1:1 molar ratio) of the isomeric amines diisopropylamine (S1) and triethylamine (S2) was continuously fractionated over 14 days without any observable decrease in selectivity (see scheme).
