  • Polymeric phosphite composition and hydrocyanation of unsaturated organic compounds and the isomerization of unsaturated nitriles
    Patent number: 6855799
    Abstract: A polymeric composition, a process for producing the composition, and a process for using the composition in, for example, hydrocyanation or isomerization are disclosed. The composition comprises repeat units derived from (1) a carbonyl compound, a monomer, and phosphorochloridite; (2) phosphorus trichloride, a polyhydric alcohol, and an aromatic diol; or (3) combinations of (1) and (2) in which the monomer can be a polyhydric alcohol, an amine, combinations thereof. The composition can further comprise a Group VIII metal and optionally a Lewis acid.
    Type: Grant
    Filed: May 25, 2001
    Date of Patent: February 15, 2005
