This invention relates to a new process for the preparation of aldehydes by the reaction of carbon monoxide and hydrogen with olefins in the presence of hydroformylation catalyst. The invention also relates to a new supported cobalt hydroformylation catalyst and a process for catalyst preparation.

Cobalt hydroformylation catalysts

Ethylene glycol and lower monohydric alcohols are prepared from syngas in good yield by contacting a mixture of carbon monoxide and hydrogen with a catalyst system comprising a ruthenium-containing compound and a special substituted aromatic compound both dispersed in a low melting quaternary phosphonium salt and heating the resulting mixture at a temperature of at least 150.degree. C. and a pressure of at least 500 psi for sufficient time to produce the desired ethylene glycol and monohydric alcohols, and then removing the same from the reaction mixture.

Ethylene glycol and lower monohydric alcohols are prepared from syn gas in improved yields by contacting a mixture of carbon monoxide and hydrogen with a catalyst system comprising a ruthenium-containing compound and a special manganese-containing compound, both dispersed in a low melting quaternary phosphonium compound, and heating the resulting reaction mixture at a temperature of at least 150.degree. C. and a pressure of at least 500 psi for sufficient time to produce the desired ethylene glycol and monohydric alcohols, and then recovering the same from the reaction mixture.
