Under the conditions: P(H-2)=2.0MPa, T=90degreesC, styrene could be completely transferred and the yield of ethylbenzene reached up to 99.5%. After simple decantation, the catalyst could be reused for ten times without decreasing in activity.展开更多
Effects on the recycling efficiency of thermoregulated phase-separable Rh/PETPP (P-[p-C6H4O(CH2CH2O)nH]3, N=3n) complex catalyst involved in hydroformylation of 1-decene are for the first time presented.

It was found that the loss of Rh is dependent greatly on the composition of phosphine ligand PETPP and the organic solvent employed in the reaction.展开更多
