Abstract: Oxygenated organic compounds, e.g. esters, aldehydes, and amides, are prepared by reacting an olefinically unsaturated compound with carbon monoxide and a compound containing a replaceable hydrogen atom in the presence of a catalyst comprising cobalt or ruthenium carbonyl and a promoter ligand. The promoter ligand is selected from the group consisting of heterocyclic nitrogen compounds and phosphorus or sulfur oxides. These reactions are carried out under relatively mild conditions of temperature and pressure.

Abstract: The alkali metal methylate catalyst used in the preparation of dimethylformamide from dimethylamine and carbon monoxide can be preserved, recycled and reused if the reaction mass contains dimethylamine in excess of the stoichiometric amount at all times.

Abstract: Oxygenated organic compounds, e.g. esters, aldehydes, and amides, are prepared by reacting an olefinically unsaturated compound with carbon monoxide and a compound containing a replaceable hydrogen atom in the presence of a catalyst comprising cobalt carbonyl and a polyamine promoter ligand. These reactions are carried out under relatively mild conditions of temperature and pressure.

Abstract: Dialkyl formamides may be prepared by treating the corresponding dialkyl amine with carbon dioxide and hydrogen in the presence of a transition metal hydrogenation catalyst at a temperature in the range of from about 100.degree. to about 400.degree. C. and a pressure in the range of from about 5 to about 300 atmospheres. The reaction is exemplified by treating dialkyl amine with carbon dioxide and water in the presence of a copper chromite to form N,N-dimethylformamide.

Abstract: A process for producing dimethylformamide which comprises reacting methanol and ammonia to give methylamines, separating a dimethylamine-trimethylamine mixture from the methylamines, and reacting the dimethylamine-trimethylamine mixture with carbon monoxide to produce dimethylformamide.

Abstract: A heterogeneous process for selectively producing acetamides in which the acyl nitrogen is otherwise bonded to methyl, ethyl, hydrogen or combinations thereof which comprises contacting a mixture of carbon monoxide, hydrogen and a nitrogen-containing compound selected from the group consisting of ammonia, nitric oxide and mixtures thereof with a heterogeneous solid catalyst comprising rhodium and manganese. The acetamides of the invention are formed in a collective amount of at least 25 weight percent of the total amide products of the reaction.
