Abstract
This communication describes the use of nanofiltration (NF) membranes for e fficient separation and recycling of phase-transfer catalysts, using the co nversion 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 o ver a cycle of three consecutive reactions.
