5-isopropyl-3-aminomethyl-2-methyl-1-amino-cyclohexane (carvone diamine), and method for the production thereof |
摘要 |
The present invention relates to 5-isopropyl-3-aminomethyl-2-methyl-1-aminocyclohexane (carvonediamine) and to a process for preparation thereof by a) reacting carvone with hydrogen cyanide, b) then reacting the carvonenitrile obtained in stage a) with ammonia in the presence of an imine formation catalyst and c) then reacting the carvonenitrile imine-containing reaction mixture obtained in stage b) with hydrogen and ammonia over hydrogenation catalysts. The present invention further relates to the use of carvonediamine as a hardener for epoxy resins, as an intermediate in the preparation of diisocyanates, as a starter in the preparation of polyetherols and/or as a monomer for polyamide preparation.
