It has been found that certain polyhydroxy alkyl amines are very readily soluble in water, alcohols and mixtures thereof. The concentrated solutions described consist essentially of water, alcohols, preferably C1 to C3 alcohols, or water/alcohol mixtures as solvents and at least one dialkyl aminopropyl glucamine of the following formula (1), Z-NH-CH2CH2CH2-NR1R2 in which R1 and R2 are the same or different and are C1 to C4 alkyl or hydroxyalkyl with 2 to 4 carbon atoms and Z is a linear polyhydroxy hydrocarbon radical with at least three possibly oxalkylised OH groups. The concentrated solutions are particularly suitable for the production of the corresponding polyhydroxy alkyl carboxylic acid amides.
On a découvert que certaines polyhydroxyalkylamines présentent une forte solubilité dans l'eau, les alcools et dans les mélanges d'eau et d'alcools. Les solutions concentrées décrites se composent sensiblement d'eau, d'alcools, de préférence d'alcools C¿1? à C¿3?, ou de mélanges eau/alcool sous forme de solvants et d'au moins une dialkylaminopropyl-glucamine de la formule (1) suivante: Z-NH-CH¿2?CH¿2?CH¿2?-NR?1¿R?2¿ où R?1¿ et R?2¿ sont identiques ou différents et représentent alkyle C¿1? à C¿4? ou hydroxyalkyle avec 2 à 4 atomes de carbone et où Z représente un résidu linéaire de polyhydroxy-hydrocarbure avec au moins trois groupements OH éventuellement oxalkylés. Les solutions concentrées s'avèrent particulièrement avantageuses dans la production des amides d'acide polyhydroxyalkyl carboxylique.
