  • Preparation of anhydrous 2-amino-1-methoxypropane
    Patent number: 5910612
    Abstract: The process for preparing anhydrous 2-amino-1-methoxypropane proceeds by(a) admixing a 2-amino-1-methoxypropane-containing water-containing reaction mixture, obtainable from the reaction of 1-methoxy-2-propanol with ammonia on a catalyst, with sodium hydroxide solution, forming an aqueous phase containing sodium hydroxide solution and a 2-amino-1-methoxypropane-containing phase,(b) separating off the 2-amino-1-methoxypropane-containing phase from the aqueous phase and(c) distilling the 2-amino-1-methoxypropane-containing phase, an azeotrope of water and 2-amino-1-methoxypropane, which is recycled to step (a) or (b), first being produced and anhydrous 2-amino-1-methoxypropane then being produced.

  • Preparation of N-substituted cyclic amines
    Patent number: 5847131
    Abstract: N-Substituted cyclic amines are prepared by reacting diols with primary amines over a copper-containing catalyst which is obtainable by impregnation of an inert support with an aqueous solution of an ammine complex of a readily thermally decomposable copper compound and subsequent drying and calcination and contains from 5 to 50% by weight of copper, calculated as CuO.
