PROCESS FOR PRODUCING POLYCYLINIC DIOLS

摘要

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.
