Abstract
Dialdehydes and diols are produced by subjecting dicyclopentadiene or a similar cyclic diolefin to the addition of carbon monoxide and hydrogen under oxo conditions but pressures below 300 atmospheres in the presence of a diluent, a polymerization inhibitor, a stabilizer, and cobalt, or a cobalt compound capable of yielding cobalt hydrocarbonyl, and in presence of metallic cobalt or iron followed by catalytic hydrogenation. When metallic cobalt is used as catalyst, it may function also as polymerization inhibitor. In examples, dicyclopentadiene is caused to react with water-gas in benzene as diluent, and with hydroquinone as stabilizer, with ferrum reductum or metallic cobalt as polymerization inhibitor, and with aqueous cobalt sulphate and magnesium sulphate, or a reduced cobalt/magnesia kieselguhr, as catalyst, to give the dialdehyde with some monoaldehyde and diol and other products. The reaction mixture may be catalytically hydrogenated without or with isolation to give mixtures containing monols, diols and resinous products.
