The present invention concerns a catalyst system and a process for selectively producing alcohols from olefines and synthesis gas. The catalyst system comprises one or several metal cluster compounds belonging to the cobalt group on an inorganic carrier and an amine of the form NR.sub.1 R.sub.2 R.sub.3, where R.sub.1,R.sub.2 and R.sub.3 are either hydrogen or an aliphatic or aromatic group containing 1 to 8 carbon atoms.

Catalyst system and process for producing alcohols from olefines and

A two step process for producing isobutylene from propylene and synthesis gas. In the first step, propylene is contacted with synthesis gas at elevated temperature in the presence of a catalyst system containing a mixture of monometal compounds M.sub.4 (CO).sub.12 and M'.sub.4 (CO).sub.12 and/or bimetal compound M.sub.2 M'.sub.2 (CO).sub.12 where M and M' are different metals of the cobalt group. The alcohol mixture thus-obtained is dehydrated in the second step, to produce a product fraction containing a large amount of isobutylene.

Two step process for producing isobutylene from propylene and sythesis

A catalyst for directly converting olefins to alcohols by hydroformylation in a single step, the catalys comprising a mixture of two monometal cluster compounds M.sub.4 (CO).sub.12 and M'.sub.4 (CO).sub.12 where M and M' are compounds of the cobalt group.
