  • Hydroformylation of dicyclopentadiene to its dimethanolic derivatives
    Patent number: 4262147
    Abstract: Dicyclopentadiene is selectively and substantially hydroformylated to its dimethanolic derivatives by a process comprising contacting dicyclopentadiene with a gaseous mixture of carbon monoxide and hydrogen at a temperature of at least about 100.degree. C. and a pressure of at least about 1,000 psig in the presence of a catalytic amount of a catalyst consisting essentially of a rhodium-cobalt bimetallic cluster, such as Rh.sub.2 Co.sub.2 CO.sub.12, supported on an amine resin, such as DOWEX.RTM. MWA-1.
    Type: Grant
    Filed: March 16, 1979
    Date of Patent: April 14, 1981
    Assignee: The Dow Chemical Company
    Inventors: Philip E. Garrou, George E. Hartwell
  • Amine-resin supported rhodium-cobalt bimetallic clusters as novel hydroformylation catalysts
    Patent number: 4197414
    Abstract: Olefins are converted to alcohols by a one-step, hydroformylation process comprising contacting an olefin, such as 1-hexene, with a gaseous mixture of carbon monoxide and hydrogen in the presence of a catalyst prepared by loading a bimetallic cluster of the formula: Rh.sub.x Co.sub.y CO.sub.12 wherein both x and y are independently integers 1-3 with the proviso that .SIGMA.(x+y)=4, onto an amine resin, such as Dowex.RTM. MWA-1.
    Type: Grant
    Filed: October 18, 1978
    Date of Patent: April 8, 1980
    Assignee: The Dow Chemical Company
    Inventors: George E. Hartwell, Philip E. Garrou
  • Amine-resin supported rhodium-cobalt carbonyl bimetallic clusters as novel hydroformylation catalysts
    Patent number: 4144191
    Abstract: Olefins are converted to alcohols by a one-step, hydroformylation process comprising contacting an olefin, such as 1-hexene, with a gaseous mixture of carbon monoxide and hydrogen in the presence of a catalyst prepared by loading a bimetallic cluster of the formula: Rh.sub.x Co.sub.y CO.sub.12 wherein both x and y are independently integers 1-3 with the proviso that .SIGMA. (x+y)=4, onto an amine resin, such as Dowex.RTM. MWA-1.
    Type: Grant

  • Process for preparing bispicolyamine
    Patent number: 4080338
    Abstract: Bispicolylamines are prepared by reacting (a) cyanopyridine with (b) hydrogen in the presence of a catalytic amount of (c) a palladium or carbon catalyst which has been preconditioned by contact with a reacting mixture of (a) and (b) for a time sufficient to cause said catalyst to preferentially produce bispicolylamine. The reaction is normally conducted under autogenous or superatmospheric pressure at a temperature of from about 20.degree. to about 75.degree. C in a lower alkanol (e.g., methanol) as the reaction medium.
