CONCENTRATED SOLUTIONS OF POLYHYDROXYALKYL AMINES AND THEIR USE, PARTICULARLY FOR PREPARING AMIDES OF POLYHYDROXYALKYL CARBOXYLIC ACIDS

摘要

It has been found that certain polyhydroxyalkylamines have a particularly good solubility in water, alcohols and in mixtures of water and alcohols. The concentrated solutions described consist essentially of water, alcohols, preferably C1-C3-alcohols, or water/alcohol mixtures as solvent and at least one dialkylaminopropylglucamine of the formula 1 below Z-NH-CH2CH2CH2-NR1R2(1) where R1 and R2 are identical or different and are C1-C4-alkyl or hydroxyalkyl having from 2 to 4 carbon atoms and Z is a linear polyhydroxyhydrocarbon radical having at least three OH groups which may, if desired, be alkoxylated, The concentrated solutions are particularly useful for preparing the corresponding polyhydroxyalkylcarboxamides.
