  • Process for making nitriles
    Patent number: 9040735
    Abstract: The present invention relates to a process for hydrocyanating 3-pentenenitrile. The process can include feeding 3-pentenenitrile and HCN to a hydrocyanation reaction zone that includes a Lewis acid promoter, nickel, and a phosphorus-containing ligand. In various embodiments, the process can also include controlling water concentration within the hydrocyanation reaction zone sufficient to maintain a high activity of the ligand catalyst complex while recycling at least a portion of the ligand catalyst complex.
    Type: Grant
    Filed: October 4, 2012
    Date of Patent: May 26, 2015

  • Process for oxidation of cyclohexane
    Patent number: 6888034
    Abstract: Process for oxidizing cyclohexane in which oxygen is contacted with cyclohexane at a pre-selected feed rate in a first reaction zone and unconsumed oxygen is contacted with cyclohexane in a second reaction zone in which the cyclohexane feed rate is lower than the pre-selected feed rate.
    Type: Grant

  • Process for removing water from organoborane compounds
    Patent number: 6461481
    Abstract: A method of removing water from wet organoborane by dissolving the wet organoborane in an organic solvent in which water is incompletely soluble, decanting any insoluble water, and distilling the organic phase to remove water which may be contained therein.
    Type: Grant
