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.
