Mono-and tris(amino-loweralkoxy)-(alkyl)-polyoxyalkylene compounds and method of preparation
Abstract
Abstract A PROCESS IS DISCLOSED FOR MANUFACTURING NOVEL AMINES COMPRISING REACTING AN OLEFIN NITRILE SUCH AS ACRYLONITRILE WITH VARIOUS POLYHYDROXY COMPOUNDS FOLLOWED BY HYDROGENATION OF THE NITRILE GROUP TO OBTAIN THE AMINES. SOME EXAMPLES OF THE AMINES PREPARED COMPRISE: (1) A-(3-AMINOPROPOXY-W-(N-BUTYL)-POLY-1,2-OXYPROPYLENE (2) A-W-BIS-(3-AMINOPROPOXY)-POLY-1,2-OXYPROPYLENE1,4-OXYBUTYLENE (3) A-W-BIS-(3-AMINOPROPOXY)-POLY-1,2-OXYPROPYLENE (4) A-W-BIS-(3-AMINOPROPOXY)-POLY-1,2-OXYBUTYLENE (5) 1,2,6-TRIS(A-(3-AMINOPROPOXY)-POLY-1,2-OXYPROPYL)HEXANE (6) 1,2,3-TRIS(A-(3-AMINOPROPOXY)-POLY-1,2-OXYPROPYL) PROPANE (7) THE TRIS (3-AMINOPROPOXY)-ETHER OF OXYPROPYLATED TRIS-(4-HYDROXYPEHNYL)PROPANE THE HYDROGENATION IS ADVANTAGEOUSLY CONDUCTED IN THE PRESENCE OF A TERTIARY AMINE SUCH AS TRIMETHYLAMINE, MIXTURES OF A TERTIARY AMINE AND AMMONIA OR AMMONIA WHEN THE NITRILE IS FREE FROM POLYMERIC NITRILES. THE AMINES ARE USEFUL AS COMPONENTS OF POLYURETHANE ELASTOMERS, POLYURETHANE FOAMS, FLEXIBLE AND RIGID POLYAMIDE RESINS AND EPOXY RESIN HARDENERS.
