If the dyestuffs are reactive dyestuffs, these are as a rule isolated and used in the form of their alkali metal salts, in particular the lithium, sodium or potassium salts.

150 g (0.5 mol) of 81% pure sodium 2-chloro-5-nitrobenzenesulphinate are presented in 300 ml of water at pH 8-8.5 and 60.degree. C. To this are added dropwise in the couse of about 8 hours 200 ml of propylene oxide while the pH of the reaction mixture is constantly maintained between 7.5 and 9.5 with 20% strength sulphuric acid. After cooling down, the solids are filtered off with suction and washed twice with 200 ml of water. Drying at 70.degree. C. in vacuo gives 118 g of colourless 2-chloro-5-nitrophenyl 2-hydroxypropyl sulphone.

EXAMPLE 24

A solution, obtained in Example 23, of 20.5 g of 5-amino-2-(2-aminoethylamino)-phenyl 2-hydroxy-1-propyl sulphone in 215 ml of water and 180 ml of isopropanol is brought to pH 6.0 with concentrated hydrochloric acid. To this are added 9.2 g of 2,3,5,6-tetrachloroquinone, the temperature is raised to 40.degree. C., and the pH is maintained at 5.5-5.8 with 2N sodium carbonate solution. After 2 hours the temperature is raised to 50.degree. C. and the pH is maintained some more until the consumption of sodium carbonate has ceased. To the brown solution obtained are added dropwise 550 ml of 25% strength sodium chloride solution in the course of 2 hours, the thrown precipitate is filtered off with suction, and the filter cake is washed with dilute sodium chloride solution and with acetone. This gives a brown product of the formula ##STR226##

EXAMPLE 25

11.9 g of the condensation product obtained in Example 24 are gradually added at -5.degree. to 0.degree. C. to 50 ml of 20% strength oleum. After the addition, the temperature of the solution is allowed to rise to 15.degree. C., and 7.7 g of potassium peroxodisulphate are added in the course of 45 minutes with cooling at such a rate that the temperature is maintained at 20.degree. C. The reaction mixture is stirred at 20.degree. C. for about 2 hours. It is then carefully added to 270 g of ice, the precipitated product is filtered off with suction at 0.degree.-10.degree. C., and the filter cake is washed with 300 ml of water until sulphate-free. The product obtained conforms to the formula ##STR227## and after neutralisation gives a clear blue solution in water. The product can be dried at 50.degree. C. in a circulating air cabinet.

EXAMPLE 26

11.2 g of the triphendioxazine component of Example 25 in the form of a moist filter cake are dissolved in 200 ml of water by setting a pH of 8.0. The bluish violet solution is immediately cooled down to 0.degree. C. and a solution of 2-(2,4-difluorotriazinyl)-aminobenzene-1,4-disulphonic acid or of the partial sodium salt, which is prepared from 9.1 g of 2-aminobenzene-1,4-disulphonic acid and 4.9 g of cyanuric fluoride by the method of Example 12, is then added in the course of 5 minutes.

In the reaction mixture the pH is maintained at 8.0 with 2N sodium hydroxide solution and the temperature at 0.degree.-5.degree. C. After the reaction has ended, the solution has turned a pure blue colour. The temperature is then allowed to rise to 20.degree. C., and the dyestuff is salted out of the solution with potassium chloride. The precipitate is filtered off with suction, and the filter cake is washed with 20% strength potassium chloride solution and after addition of a little phosphate buffer solution is dried at 45.degree. C. in vacuo. This gives a dyestuff of the formula ##STR228## which dyes cellulose fibres from a long liquor in bright blue shades. C.I. indicator number 13. .rho..sub.max =616 nm in water.
