    摘要: Textile treatment preparations based on the condensates of aliphatic monocarboxylic acids or amide-forming derivatives thereof with optionally hydroxyl-substituted polyamines and an addition of dispersion accelerators from the group of certain monosaccharides and hydrogenation products thereof, polyols and natural and synthetic hydrophilic polymers show particularly good dispersibility, even in cold water, if the amino groups unreacted during the condensation reaction are only partly neutralized with low molecular weight, optionally hydroxyl-substituted mono- or polycarboxylic acids.

    摘要: A process is disclosed for producing fluid imidazolinium tensides by reaction of 1-hydroxyethyl-2-alkylimidazolines with neutralized quaternary agents and hydrolysis of the quaternary products thus obtained with aqueous bases. The 1-hydroxyethyl -2-alkylimidazolines are added at a high temperature to an aqueous solution of the neutralized quaternary agents at a molar proportion between imidazoline derivates and the quaternary agents from 1:1.5 to 1:3. The reaction mixture thus obtained is maintained at a temperature in a range of 70.degree. to 85.degree. C. for 30 to 120 minutes, 0.85 to 1.0 mol alkali metal hydroxides, referred to the amount of quaternary agents added during step (a), are added thereto within the 30 to 120 minutes at a temperature in the range of 75.degree. to 85.degree. C., and the reaction mixture thus obtained is maintained at a temperature in the range of 75.degree. to 90.degree. C. for 140 to 220 minutes. The end products are obtained by a process that is easy to carry out if during step (a) a solution of neutralized quaternary agents is used that contains 0.025 to 0.5 mol of carboxylic acids, referred to the amount to be added of 1-hydroxyethyl-2-alkylimidazolines, and if acids are added to the reaction mixture obtained during step (d), so that when the reaction mixture is diluted with water up to a 10 wt % concentration of the product, a pH value in the range of 7 to 10 is set.
