Claims
- 1. A process for the conversion of a C.sub.8 -C.sub.22 primary aliphatic hydrocarbon mono-alcohol to a C.sub.8 -C.sub.22 mono-amine containing from 60-85 wt. % secondary amine derivatives which comprises sparging said alcohol at a temperature of from 180.degree.-220.degree. C. in the presence of from 0.5-10 wt. % nickel hydrogenation-dehydrogenation catalyst with a gaseous mixture of ammonia and hydrogen having a volumetric ratio of 8:1 to 1:1, respectively, at a rate of from 2.2-6 wt. % ammonia per hour based on the weight of the alcohol and continuously removing water of reaction and excess ammonia, and wherein the ammonolysis reaction is carried out until the total amine nitrogen content of the reaction mixture remains substantially constant.
- 2. A process in accordance with claim 1 wherein the ammonia is introduced into said alcohols at a rate of 3-5 wt. % per hour based on the weight of the alcohol mixture.
- 3. A process in accordance with claim 2 wherein said catalyst is a supported nickel catalyst present in an amount of from about 1-4 wt. % of said alcohol mixture.
- 4. A process in accordance with claim 3 wherein the reaction temperature is from about 185.degree. to 195.degree. C.
- 5. A process in accordance with claim 4 wherein the hydrogen is introduced into said alcohols at a rate of about 25-75 vol. % based on the rate of said ammonia.
