Chemische Eigenschaften
colourless liquid
Verwenden
1,3-Diaminopropane is commonly used in the preparation of cholinesterase inhibitors and thrombosis inhibitors. It is also used as a polymer cross linkage agent, polyurethane extender and spray coatings. It is involved in the preparation of agrochemicals and pharmaceutical intermediates. Further, it acts as a building block in the synthesis of heterocyclic compounds, which finds application in textile finishing. In addition to this, it is used as a ligand and form coordination complexes. 1,3-Diaminopropane is also utilized for the production of a chelating agent used in the photo industry and for anticorrosion agents.
Vorbereitung Methode
1,3-Diaminopropane is produced in a twostage continuous process, under a pressure of 10 – 20 MPa. In a first reactor, acrylonitrile reacts with excess ammonia at 70 – 100 ℃ to give 2-aminopropionitrile and bis(cyanoethyl) amine. The mixture of aminonitriles is then hydrogenated in a downstream reactor over a fixed-bed catalyst (cobalt or nickel) at 60 – 120 ℃ to give 1,3-diaminopropane and bis (aminopropyl)amine. The yield of 1,3- diaminopropane can be increased by adding a polar solvent and water or by using a large excess of ammonia.
