CO at high temperature and pressure is caused to react on a vaporized aliphatic alcohol or ester in the presence of hydrating or hydrating and hydrogenating catalysts. MeOH and CO are passed over a mixture of Fe and Mn oxides, forming a products containing butyric and valeric acids. MeOH vapor, Co, H₂, and N₂ are passed over a Co oxide-molybdic acid catalyst, forming O compounds and N compounds, such as methylamines: Ba uranate or Fe vanadate also can be used as catalyst. MeOH and CO passed over a K chromate-K molybdate catalyst yield higher alcohols, aldehydes, and esters. EtOH and CO passed over a Cr oxide-Mn oxide catalyst give products boiling at 100°-250°, including aldehydes, acids, esters, and alcohols. MeOH, CO, H2, and N2, passed over a K₂Cr₂O-ZnO catalyst give a product containing isobutyl, n-proply-, amyl- and higher alcohols, and free or combined acids. Me formate, CO, H₂, and CH₄ passed over a catalyst prepared from KmnO₄, Zn chromate, and Cu chromate, give similar products. Co and H₂ are passed over a catalyst consisting of Cd and Cu oxides and vanadic acid, and the resulting MeOH-containing mixture is passed over a catalyst prepared from KOH, TI oxide, and KmnO₄ to produce isobutyl alcohol and other products. Purified water gas and EtOH may be passed over K₂CO₃. Zn chromate, and Cu oxide to form liquid products insoluble in H₂O. Numerous catalysts listed for effecting hydrogenation, hydration, or both.
