Then 9.2g of 2- ethylaminoethanol are added and the reaction mixture is heated to a temperature of 98°C; during heating the pH is maintained at a value between 8.5 and 9 by addition of a 4-molar aqueous solution of sodium hydroxide. The reaction mixture is cooled to 50°C and the pH is adjusted to a value of 4.5 by addition a 6-molar aqueous solution of hydrochloric acid. The precipitate is filtered off, washed with 100ml of a 10% aqueous sodium chloride solution and dried in vacuum. In this way, there are obtained 30.5g of a yellowish product.
  • Na + can be prepared in analogy to the process given in Preparation Example 1 , by replacing 9.2 g of 2-ethylaminoethanol with an equimolar amount of the corresponding amine.
  • X is as defined in the following Table 1. Compounds which precipitate after cooling to 50°C are isolated directly as sodium salts without addition of hydrochloric acid and then dried in vaccuum.
  • Na can be prepared in analogy to the process given in Preparation Example 16, by replacing 9.5 g of morpholine with an equimolar amount of the corresponding amine.
  • X is as defined in the following Table 2.
  • Compounds having high solubility are treated with a 6-molar aqueous solution of hydrochloric acid in order to adjusted the pH to a value of 4.5 before cooling to 50°C.
  • Table 2
  • the compound of formula (107) can be prepared in analogy to the process given in Preparation Example 21 , by replacing 15 g of an aqueous solution of ethylamine (70%) with a corresponding solution containing an equimolar amount of diethylamine.
  • a wash liquor is prepared by dissolving 0.8 g of a washing powder in 200 ml of tap water. 10 g of bleached cotton fabric is added to the bath and washed at 40°C over 15 minutes and then rinsed, spin-dried and ironed at 160°C.
  • washing powders A and B are used (amounts given in the following Tables 3a and 3b are in g):
