Abstract:
A composition and a process for using the composition in hydroformylation of unsaturated organic compounds are disclosed. The composition comprises a Group VIII metal and a phosphite-containing polymer having repeat units derived from (1) a carbonyl compound, a monomer, and phosphochloridite; (2) phosphorus trichloride, a polyhydric alcohol, and an aromatic diol; or (3) combinations of (1) and (2). The process comprises contacting an unsaturated compound, in the presence of the composition disclosed herein, with a fluid comprising hydrogen.
Abstract:
A polymeric, phosphorus-containing composition made by heating, in the presence of an initiator, preferably a free radical initiator, and optionally in the presence of one or more comonomers, at least one ethylenically substituted phosphonylated 2,2'-dihydroxyl-1,1'-binaphthalene or -biphenylene or at least one ethylenically substituted 2,2'-dihydroxyl-1,1'-biphenylene or -binaphthalene, with subsequent phosphonylation. Alternatively, an aryl phosphorochloridite containing at least one (meth)acrylate group is polymerized and subsequently coupled with a 2,2'-dihydroxyl-1,1'diphenylene or -binaphthalene. These polymers and the corresponding phosphonylated 2,2'dihydroxyl-1,1'-binaphthalene or biphenylene monomers may be combined with a group VIII metal to form catalysts for hydrocyanation, hydroformylation or unsaturated nitrile isomerization.
Abstract:
Multidentate phosphite ligands are disclosed for use in reactions such as hydrocyanation and isomerization. The catalyst compositions made therefrom and the various catalytic processes which employ such multidentate phosphite ligands are also disclosed. In particular, the ligands have heteroatom-containing substituents on the carbon attached to the ortho position of the terminal phenol group.
