Abstract
A polycyclic diol is produced by a hydroformylation of a polycyclic bridged ring olefinic compound having another double bond, formyl or methylol group, in the presence of a cobalt compound and a phosphine as a catalyst in the presence of a saturated hydrocarbon or aromatic hydrocarbon. Polycyclic diols such as tricyclodecanedimethylol are useful for hardeners for non-solvent type lacquers polyurethanes having heat resistant and chemical resistance or epoxy resins.
Claims12
A process for producing tricyclodecanedimethylol comprising reacting dicyclopentadiene with carbon monoxide and hydrogen in the presence of a catalyst comprising a cobalt carbonyl-phosphine complex in a suitable solvent, whereby a reaction mixture is formed, wherein the temperature, pressure, and concentration of reagents are chosen so that the F parameter defined by the following equation:
- ##EQU2## is greater than 5.
