Claims
- 1. A process for the preparation of a monocarboxylic acid which comprises reacting carbon monoxide and a hydrocarbyl alcohol in the presence of an iodide and in the presence of a catalyst consisting essentially of nickel or a nickel compound and a phosphine promoter, said iodide being employed in the amount of 10 to 200 mols, expressed as I, per 100 mols of alcohol, and said reacting being carried out at a temperature of 25.degree.-350.degree. C. and at a carbon monoxide partial pressure of 1-10,000 psi.
- 2. A process as defined in claim 1, wherein the acid is a lower alkanoic acid, and the hydrocarbyl alcohol is a lower alkyl alcohol.
- 3. A process as defined in claim 1, wherein the acid is acetic acid and the hydrocarbyl alcohol is methanol.
- 4. A process for the preparation of a monocarboxylic acid which comprises reacting carbon monoxide and a hydrocarbyl alcohol in the presence of an iodide and in the presence of a catalyst consisting essentially of nickel or a nickel compound and a phosphine promoter, said iodide being employed in the amount of 10 to 200 mols, expressed as I, per 100 mols of alcohol, and said reacting being carried out at a temperature of 25.degree.-350.degree. C. and at a carbon monoxide partial pressure of 15 to 1,000 psi.
- 5. A process for the preparation of a monocarboxylic acid which comprises reacting carbon monoxide and a hydrocarbyl alcohol in the presence of an iodide and in the presence of a catalyst consisting essentially of nickel or a nickel compound and a phosphine promoter, said iodide being employed in the amount of 10 to 200 mols, expressed as I, per 100 mols of alcohol, and said reacting being carried out at a temperature of 25.degree.-350.degree. C. and at a carbon monoxide partial pressure of 30-200 psi.
