Claims
- 1. In the production of an amine by the aminomethylation of an olefin wherein an olefin is reacted with ammonia, a primary amine or a secondary amine in the presence of carbon monoxide and water or hydrogen, and in the production of an amine by reaction of an aldehyde with ammonia, a primary amine or a secondary amine in the presence of carbon monoxide and water or hydrogen, and wherein a homogeneous catalyst in the form of a solution of a catalyst in a solvent is used, the improvement which comprises employing a mixed ruthenium carbonyl/iron carbonyl as a catalyst.
- 2. The improvement of claim 1 wherein the reactant with the amine is an olefin.
- 3. The improvement of claim 2 wherein the olefin has a terminal vinyl group and the resulting amine product is predominantly of the type
- >CH--CH.sub.2 --CH.sub.2 --NR.sub.1 R.sub.2
- wherein R.sub.1 and R.sub.2 are hydrogen or organic groups and may form parts of a cyclic structure.
- 4. The improvement of claim 1 wherein the molar ratio of iron to ruthenium is about 25% to 75% iron and 75% to 25% ruthenium.
- 5. The improvement of claim 2 wherein the reactants are the olefin, carbon monoxide and water and the solution is made alkaline with the hydroxide, carbonate or bicarbonate of sodium, potassium, caesium or rubidium.
- 6. The improvement of claim 2 wherein the reactants are an olefin, carbon monoxide and hydrogen and the solution is made alkaline by an alkoxide or phenolate of sodium, potassium, caesium or rubidium.
