  • Hydroxylation of olefins
    Patent number: 4393253
    Abstract: A method for preparing polyols such as diols by catalytic hydroxylation of an olefinic compound by reacting the olefinic compound with an organic hydroperoxide and water in the presence of a catalyst comprising osmium compound and a specific halide co-catalyst is disclosed.
    Type: Grant
    Filed: October 9, 1981
    Date of Patent: July 12, 1983
    Assignee: Exxon Research & Engineering Co.
    Inventors: Robert C. Michaelson, Richard G. Austin
  • Hydroxylation of olefins
    Patent number: 4390739
    Abstract: A process directed to the hydroxylation of olefins by reacting said olefins with an oxygen containing gas and water in the presence of a catalyst composition comprising (i) a catalytically active metal oxide such as OsO.sub.4, (ii) as a co-catalyst I a transition metal salt such as CuBr.sub.2, and (iii) optionally a co-catalyst II salt such as tetra ethyl ammonium bromide is disclosed.

  • Hydroxylation of olefins
    Patent number: 4314088
    Abstract: Method for preparing polyols such as diols and triols by the homogeneous catalytic hydroxylation of an olefinic compound by contacting the olefinic compound with an organic hydroperoxide in an inert polar solvent containing catalytic amounts of an osmium compound and a halide and at least a stoichiometric amount of water based on the amount of said olefinic compound.
