Hydroformylation of 1-butene catalyzed by water-soluble Rh-BISBIS complex in aqueous two-phase catalytic system

摘要

This paper reports the hydroformylation of 1-butene catalyzed by RhCI(CO)(TPPTS)_2 (TPPTS:P(m-C_6H_4SO_3Na)_3) and BISBIS (sodium salt of sulfonated 2,2'-bis(diphenylphosphinomethyl)-1,1'-biphenyl) in aqueous/organic two-phase catalytic system.The effects of reaction parameters on the catalytic activity and regioselectivity were investigated under the optimum reaction condiitons:130 deg C,2.5 MPa (syngas pressure),[BISBIS]/[Rh]=5,[1-butene]/[H_2]/[CO]=1:1:1,[1-butene]/[Rh]=10 400,TOF and the regioselectivity for n-valeraldehyde were 2987 h~(-1) and 98%,respectively.
