Method of producing new reactive dyes. The subject of the invention is a method of producing new reactive dyes of general formula I, in which the DNR group is one of the radicals of general formulas 2, 3 or 4. , in which n is a numerical value of 0 or 1, Q and Q *, each independently is H, CH3, OCH3 or NHCOCH3, R is H or CH3 and R1 is Cl, OCH3, NH2 or an aniline, sulfoanilino - acid, disulfaniline or trisulfonaphthylamino, which consists in condensing 1 mole of cyanuric chloride with 1 mole of an azo compound of the general formula DNHR, in which the DNR group has the meaning given above and the second is condensed with 1 mole of phenylenediamine disulfonic acid mole of cyanuric chloride with the second amine group of phenylenediamine disulfonic acid and with 1 mole of the compound of general formula R 1 !!, in which R 1 is as defined above, excluding R 1 = Cl. R Condensation reactions are carried out gradually by mixing the reactants in an aqueous medium, with a pH of 5-7 maintained by the addition of an acid-binding agent, in order to neutralize the hydrogen chloride formed during the reaction. For the replacement of the first chlorine atom in the cyanuric chloride, it is preferable to use the reaction temperature is 0-20 ° C, while the exchange of the second chlorine atom is more preferably carried out at 30-50 ° C. The new dyes are isolated from the reaction mixture by any known method used in the preparation of water-soluble reactive dyes, for example by salting out and desetting or by spray drying the reaction mixture. It is also possible to add stabilizers to the dyes, such as alkali metal hydrogen phosphates. The new reactive dyes are valuable for dyeing cellulosic textile materials, such as those containing natural or regenerated cellulose, such as cotton, linen and viscose silk. For dyeing such materials, the new dyes are preferably used for printing, and in particular for dyeing in the bath, in conjunction with treatment with an acid-binding agent such as sodium hydroxide, sodium carbonate, silicate or acid carbonate applied before, during or after the application of the dye. the dyes used in this way react with cellulose and give different shades formed with excellent wash resistance. Moreover, these dyes show a particularly high affinity for the fiber, especially in a salt bath or in the printing process, showing a low degree of color transfer to non-dyed areas, both during washing out of unbound dye after printing and and during washing. The invention is explained, but not limited to its scope, in the following examples, in which parts are parts by weight. Example I. For a suspension of 2.0 parts of cyanuric chloride in 10 parts of acetone and 25 parts of water, a neutral solution of 5.62 parts of the disodium salt of 4- (4'-amino-2'-methylphenylazo) -4) -nitrostilbene-2,2) -disulfonic acid in 400 parts of water was added dropwise, keeping the temperature at 0-5 ° C and a pH of 6 to 7 by adding a 2N aqueous sodium carbonate solution. After the completion of the condensation, an inert solution of 2.68 parts of 1,3-phenylenediamine-4,6-disulfonic acid in 100 parts of water was added to the reaction mixture and stirred at 35-40 ° C, maintaining the pH value shflrzez; adding 2 N aqueous sodium carbonate solution. After the completion of the condensation, the reaction mixture was cooled to 5 ° G and a suspension of 2.0 parts of cyanuric chloride in 10 parts of acetone and 25 parts of water was added dropwise, keeping the temperature at 0-5 ° C and the pH at 6-7 by adding 2N. aqueous sodium carbonate and then stirred for another 2 hours until condensation was complete. An aqueous solution of 12.5 parts of a mixture of monopotassium orthophosphate and disodium orthophosphate in the proportion 1.77: 1 was added to the resulting solution, followed by sodium chloride in an amount of 15% w / v. The salted dye was drained and made into a paste with 2.5 parts of the phosphate mixture of the above-mentioned composition, and then dried under reduced pressure at 50 ° C. The obtained dye contained 3 chlorine atoms per one azo bond in the molecule, capable of exchange; applied to cellulose fiber in the presence of an acid-binding agent gave red-yellow shades with good washing resistance. Example II. To a suspension of 2 parts of cyanuric chloride in a mixture of 20 parts of acetone and 100 parts of water, with constant stirring, an neutral solution of 1.8 parts of 1-aminobenzene-3-sulfonic acid in 100 parts of water is added while stirring constantly, keeping 5. 0-6.0 by adding 2N aqueous sodium hydroxide solution, followed by stirring under the same conditions for 2 hours. The reaction mixture was filtered, then an inert solution of 2.68 parts of 1,3-diaminobenzene-4,6-disulfonic acid in 100 parts of water was added to the filtrate and stirred for 4 hours, maintaining the temperature at 50 ° C and the pH value of 5. , 0-6.0. The resulting solution was added to a suspension of 4.0 parts of cyanuric chloride in a mixture of 40 parts of acetone and 200 parts of water, maintaining a temperature of 0-5 ° C and a pH of 5.0-6.0, and the condensation reactions were continued. for 40 hours at the same temperature and the same pH value, maintained by the addition of a 2N aqueous solution of sodium carbonate. A solution of 5.79 parts of 6-amino-2- [4 '- (4' '-sulfophenylazo) -2'-sulfophenylazo] -1-naphthol-3-sulfonic acid in 200 parts of water was added to the reaction mixture. The mixture was stirred at 50 ° C for 2 hours, maintaining the pH value 5-6. The dye was lost by adding 90 parts of sodium chloride, then filtered off, washed with 15% brine and dried at room temperature. The obtained color dyed the cellulose fiber into dull red shades with excellent wash resistance. Example III. To an inert solution of 1.34 parts of 1,3-diaminobenzene-4,6-disulfonic acid in 200 parts of water was added at 0-5 ° C a solution of 4.6 parts of cyanuric chloride in 30 parts of acetone and stirred at this temperature for 24 hours, maintaining the pH value between 6 and 7 by adding a 10% aqueous solution of sodium carbonate. Unresponsive? The cyanuric chloride was removed by filtration, and the filtrate was then added to an inert solution of 3.5 parts of trisodium salt of 4-nitro-4 '- (4'r-aminonaphthyl-1 "-azo) -stilbene-2 , 2 ', 6 "-trisulfonic acid in 60 parts of water, and heated with stirring to 40 ° C. for 2 hours. 70 parts of sodium chloride and 10 parts of a mixture of monopotassium orthophosphate and disodium orthophosphate in a ratio of 1.77: 1 were added to the reaction mixture. The precipitated dye was filtered off and mixed with 2.5 parts of phosphates of the above-mentioned composition, and then dried. The dye obtained stained the cellulose fiber a red-yellow shade. Example IV. To a suspension of 1.85 parts of cyanuric chloride in 14 parts of acetone and 112 parts of ice water was added a solution of 6.45 parts of the trisodium salt of 6-amino-2- (4'-phenylazo) -1-1-naphthol-2.
