These compounds have proven to be suitable for finishing reactive and sulfur dyes.

The compounds according to the invention have a similar effect. However, it has been shown that another significant effect of the compounds according to the invention is the ability to bind metal cations in an aqueous bath. The ability to bind trivalent cations, especially ferric cations, is particularly significant, even in a strongly alkaline environment.

This pronounced chelating effect of the compounds according to the invention can be used in chemical-technological operations where some cations are a problem.

The compounds of the invention can be prepared by reacting mono- or diethanolamine or a mixture of both substances with a compound of the general formula i X ^K K r~t

The process for preparing the compounds of the invention is apparent from the following examples:

Example 1

In a glass apparatus equipped with a thermometer and a stirrer, an 83% aqueous solution is added to the batch bath.

1,3-bis(3-chloro-2-hydroxypropyl)imidazolinium sulfate 350 g at a temperature of 70 °C is gradually added monoethanolamine 122 g

The temperature increases spontaneously during the dosing, at a temperature of 80 °C the reaction mixture begins to cool and the temperature is maintained in the range of 80 - 12 °C. The dosing of monoethanolamine is completed after 50 minutes. The mixture is left to react for another 60 minutes.

Example 2

In the apparatus according to Example 1, using the same procedure, 210 g of diethanolamine is used instead of 122 g of monoethanolamine.

Example 3

Using the procedure of Example 1, instead of 122 g of monoethanolamine, a mixture of 61 g of monoethanolamine and 105 g of diethanolamine is used.

Example 4

Instead of 350 g of 1,3-bis-(3-chloro)-2-hydroxypropyl)imidazolinium sulfate, 274 g of an 80% aqueous solution of 1,3-bis(2,3-epoxypropyl)imidazolinium chloride is used. The reaction temperature is selected in the range of 25 ± 5 °C.
