Claims
- 1. A process for producing an alkylenamine, which process consists essentially of reacting ammonia and/or an alkylenamine with an alkanolamine in the presence of a catalyst comprising a mixture of niobium oxide and an inorganic acid, to obtain an alkylenamine having an increased number of alkylene chains over the ammonia and/or the alkylenamine as starting material.
- 2. The process according to claim 1, wherein the acid is boric acid, phosphoric acid or sulfuric acid.
- 3. The process according to claim 1, wherein the alkylenamine as starting material is an ethylenamine.
- 4. The process according to claim 1, wherein the alkanolamine is an ethanolamine.
