    Abstract: A process for the manufacture of aminopolyols and polyaminopolyols by continuous reductive amination of sugars in aqueous solution is described. Syrups such as corn syrups may be used directly for this process. It has been found that the lower the mol ratio of NH.sub.3 to the sugar, with a ratio of 1 as the lower limit, the higher is the degree of nitrogen incorporation into the sugar. It is essential that the streams of ammonia and aqueous sugar solution be pumped to the reaction zone separately.

    Abstract: Tertiary monomethylamines having long chain alkyl groups are advantageously prepared from unsaturated aliphatic nitriles under a low pressure at a high yield by the steps of:(a) reducing the nitriles with hydrogen in the presence of a nickel hydrogenation catalyst at 200.degree. through 230.degree. C. and under a hydrogen pressure of 0 through 10 kg/cm.sup.2 G, while the formed ammonia is removed;(b) reacting the resultant amines with a hydroxymethylation agent in the presence of the nickel catalyst at 150.degree. through 180.degree. C., while hydrogen is passed through the reaction zone under 0.3 through 7 kg/cm.sup.2 G and the formed water is removed, and;(c) reducing the resultant tertiary amines with hydrogen in the presence of the nickel catalyst at 175.degree. through 210.degree. C. and under a hydrogen pressure of 5 through 10 kg/cm.sup.2 G.
