Abstract
N-alkylamino polyols substantially free from nickel contamination are prepared by reacting N-alkylamines with reducing sugars in the presence of hydrogen and nickel catalysts under defined conditions of temperature and pressure. The polyols are characterized by their low odor and low color characteristics. Thus, high quality N-methyl glucamine, N-methyl fructamines and the like are secured.
