Communication
This communication describes the use of nanofiltration (NF) membranes for efficient separation and recycling of phase-transfer catalysts, using the conversion of bromoheptane into iodoheptane with tetraoctylammonium bromide as the PT catalyst, as an example; a solvent flux of >10 L m−2 h−1 was achieved with >99% catalyst recycle and no loss in PT catalyst activity over a cycle of three consecutive reactions.
