ABSTRACT:
Low molecular weight oxygenated compounds, and particularly ethylene glycol and methanol, are prepared from syngas in improved yields by contacting a mixture of carbon monoxide and hydrogen with a catalyst system comprising a rhodium-containing compound, an organic ligand and a special cationic polynuclear aromatic compound possessing a nitrogen atom at a ring fusion position, dissolved in a suitable solvent, 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 low molecular weight oxygenated compounds, and then recovering the same from the reaction mixture.
