    摘要: 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.

    摘要: Halides are removed from halide-containing nitrile mixtures by(a) thermally treating the halide-containing nitrile mixture,(b) subsequently adding a base to the thermally treated nitrile mixture and(c) subsequently separating off the base from the nitrile mixture.Amines are prepared by(A) reacting alkyl halides with metal cyanides in an at least two-phase reaction medium in the presence of halide-containing phase-transfer catalysts to give alkanenitriles,(B) separating off the resulting halide-containing alkanenitrile mixture phase and(C) further treating the halide-containing alkanenitrile mixture phase, as described in the stages(a)-(c) removing halides from halide-containing nitrile mixtures and(d) hydrogenating nitrites obtained in stage (c) to give amines, in the presence of suspended or fixed-bed catalysts.
