Claims
- 1. A one-step, hydroformylation process for preparing dimethanolic derivatives of dicyclopentadiene, the process comprising contacting crude dicyclopentadiene with a gaseous mixture of carbon monoxide and hydrogen at a temperature of at least 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 carbonyl bimetallic cluster loaded onto an amine resin.
- 2. The process of claim 1 wherein the catalyst is prepared by loading onto an amine resin a bimetallic cluster of the formula:
- Rh.sub.x Co.sub.y (CO).sub.12
- wherein x and y are individually integers of 1-3 with the proviso that .SIGMA.(x+y)=4.
- 3. The process of claim 2 wherein the catalyst comprises at least about 1 weight percent rhodium and at least about 0.5 weight percent cobalt.
- 4. The process of claim 3 wherein the amine resin comprises cross-linked, essentially water-insoluble swellable gel or macroporous beads.
- 5. The process of claim 4 wherein the amine resin comprises a cross-linked polymer matrix having pendant amine functionality of the formulae --N(R).sub.2 and/or --NHR'N(R).sub.2 wherein each R is individually hydrogen or C.sub.1 -C.sub.6 alkyl, R' is C.sub.2 -C.sub.6 alkylene, and the open valence is the bond that joins the functionality to the polymer matrix.
- 6. The process of claim 5 wherein x and y are each 2.
- 7. The process of claim 6 wherein the hydrogen and carbon monoxide are present in a hydrogen:carbon monoxide mole ratio of between about 1:10 and 10:1.
- 8. The process of claim 7 wherein the catalyst (Rh-Co metal basis) is present in an amount of at least about 0.1 weight percent based upon the weight of the dicyclopentadiene.
- 9. The process of claim 8 wherein the hydrogen and carbon monoxide are present in a hydrogen:carbon monoxide mole ratio of between about 1:1 and 2:1.
- 10. The process of claim 9 wherein the crude dicyclopentadiene comprises at least about 70 weight percent dicyclopentadiene.
