Abstract

The subject of the present invention is a catalyst with increased durability based on compn. of (a) an inert, porous substrate, (b) an ionic liq., (c) Rh, (d) a phosphorus-contg. org. ligand, (e) at least an org. amine. A further the subject of the present invention is a procedure for the hydroformylation of olefin-contg. hydrocarbon mixts. to aldehyde mixts. whereby: (a) the water content of the olefin-contg. hydrocarbon mixt. is adjusted to ≤20 ppm, (b) the content of multifunctional unsatd. compds. in the olefin-contg. hydrocarbon mixt. is adjusted continually to ≤3000 ppm, (c) the mol. ratio of org. amines to phosphorus-contg. ligands is ≥4:1; and (d) the mol. ratio of phosphorus-contg. org. ligand to Rh is ≥10:1. A typical catalyst consists of silica support, rhodium acetylacetonate dicarbonyl, bis(2,2,6,6-tetramethyl-4-piperidyl) sebacate, 6,6'-[[3,3'-di-tert-butyl-5,5'-dimethoxy[1,1'-biphenyl]-2,2'-diyl]bis(oxy)]bis[dibenzo[d,f][1,3,2]dioxaphosphepin] and 1-ethyl-3-methylimidazolium bis(trifluoromethanesulfonyl)imide and a typical reaction feed contains 1-butene, isobutene, cis-2-butene, trans-2-butene, n-butane, and isobutane, with the product being n-pentanal.
