Abstract
Rhodium complexes of [1-propyl-3-methylimidazolium]2 [PhP(C6H4SO3-3)2] dissolved in the ionic liquid, 1-butyl-3-methylimidazolium hexafluorophosphate catalyse the hydroformylation of oct-1-ene at a constant rate for >20 h in a continuous flow process in which the substrate, gases and products are transported in and out of the reactor dissolved in scCO2; <1 ppm rhodium is present in the collected product.Keywords
