B. Ellis et al., Linear dimerisation of but-l-ene in biphasic mode using buffered chloroaluminate ionic liquid solvents, CHEM COMMUN, (4), 1999, pp. 337-338
The use of a buffered ionic liquid as a solvent for catalysts known to prod
uce linear dimers from but-1-ene has been explored; this resulted in a sign
ificant enhancement of the activity of known catalysts, combined with the r
etention of both dimer selectivity and product linearity; in addition, the
biphasic mode of operation allows easy catalyst recovery and recycle.
