Based on the thermoregulated ionic liquid biphasic system proposed by our research group,the phase diagrames of IL350-toluene-n-heptane,IL550-toluene-n-heptane and IL750-toluene-n-heptane are studied in detail.IL750-toluene-n-heptane biphasic system is selected to be the best system for its good thermoregulated character.In this thermoregulated ionic liquid biphasic system,the ligand TPPTS for the Rh/P-catalyzed hydroforrnylation of 1-dodecene is studied.It is found that when the composition is IL750:...
