      Yerfaliren for the preparation of a condensation product that can be used as a reservation agent. It has been found that one arrives at a valuable compound which, for example, can be used as a reservation agent for wool or silk against staining with substantive dyes, if one mole.

      is produced according to the example of Swiss patent no. "154995 and the amount corresponding to one gram molecule is added to about 15 liters of hot water using the agitator and brought into a slightly alkaline solution by gradually adding 130 grams of soda.

    About 160 g of whiting chalk are added and, with thorough stirring, at 85-90 'l00 g of 1,2,4-trichlorberizole-5-sulfochloride. The reaction sets in after a while with strong foaming of the mixture, and the reduction product is deposited in the form of a viscous, gradually thinning oil on the walls of the reaction vessel and on the surface of the liquid. The mixture is heated at 95 for about 1 hour while stirring, then made weakly Congo acidic with crude hydrochloric acid and allowed to cool.

   The clear broth can be poured off the lime salt adhering to the bottom of the vessel in solid chunks and this can be redissolved with about 10 liters of hot water with the addition of soda until the broth has a weakly alkaline reaction.

   The precipitated calcium carbonate is suctioned off, about 100 grams of table salt are added to the still warm solution and acidified with glacial acetic acid, whereupon the bis- (1. 2. 4-trichlorobenzene-5-sulfonyl-3'-amino berizol-1'- sulfonyl-3 "-aminobenzene-1" -sulfonyl- 3 "'- aminobenzene-1"' - sulfonyl) -4 "", 4 "" '- di-aminostilbene-2 "",

PATENTANSPRUCH: Verfahren zur Darstellung eines Konden sationsproduktes, dadurch gekennzeichnet, dass man 1 Mol. Bis-(3-aminobenzol-l-sulfonyl- 3'- aminobenzol -1'- sulfonyl) - 4", 4"'-diamino- stilberi-2", 2"'-disulfosärii#e mit 2 Mol. 3-Nitro- benzolsulfochlorid kondensiert, das erhaltene Produkt zur Diaminoverbindung reduziert und letztere mit 2 37o1. 1.2.4-Triclilorbenzol-5- sulfochlorid vereinigt. PATENT CLAIM: Process for the preparation of a condensation product, characterized in that 1 mol. Bis- (3-aminobenzene-1-sulfonyl- 3'-aminobenzene -1'-sulfonyl) - 4 ", 4" '- diamino stilberi- 2 ", 2" '- disulfosärii # e condensed with 2 mol. 3-Nitrobenzenesulfochlorid, the product obtained is reduced to the diamino compound and the latter with 2 37o1. 1.2.4-triclilobenzene-5-sulfochloride combined. Der so erhältliche ungefärbte Endstoff, der sich beispielsweise als Natrium- oder Ammoniumsalz leicht in Wasser löst, kann als Reversierungsmittel benutzt werden, da er in hohem Masse die Eigenschaft hat, Wolle und Seide in Mischgeweben vor Anfärbung mit substantiven Farbstoffen zu schützen. The uncoloured end product that can be obtained in this way, which dissolves easily in water as the sodium or ammonium salt, for example, can be used as a reversing agent because it has the property of protecting wool and silk in mixed fabrics from being stained with substantive dyes.
