  Process for the preparation of a condensation product which can be used as a preservative. It has been found that one arrives at a valuable compound that can be used, for example, as a reservation agent for wool or silk against staining with substantive dyes, if 1 mole of bis (3-aminobenzene-l-sulfonyl-3'-amino benzene -1'-sulfonyl-3 "-aminobenzene-1" -sulfonyl) - berrzidine-m, m'-disulfonic acid condensed with 2 moles of nitrobenzenesrrlfochlorid,

   the product obtained is reduced to the diamino compound and the latter is combined with 2 ltfol 1,2,4-trichlorobenzene-5-sulfochloride.

   The calcium carbonate precipitated in this process is filtered off with suction and the Brülle mixed with a little sodium chloride solution is acidified with acetic acid. The sodium salt of bis (1,2,4-trichlorobenzene-5-sulfonyl-3'-aminobenzene -1'-sulfonyl-3 " - Aminobenzene -1 "- sulfony 1-3" '- aminobenzene-1 "' - sulfonyl-3" "- aminobenzene-1" "- sulfonyl) -benzidine-m, m'-disulfonic acid of the formula in at first more viscous,

   soon a crumbly, crystalline shape emerges. After vacuuming and drying, it forms an almost colorless powder that, like the corresponding ammonium salt, dissolves easily in warm water and has the property to protect wool and silk in mixed fabrics against staining with nouns dyes.

Claim: Process for the preparation of a condensation product, characterized in that 1 .Hol bis- (3-aminobenzene-1-sulfonyl-3'-aminobenzene-1'-sulfonyl -3 "- aminobenzene -1" - sulfonyl) -benzidine -m, m'-disulfonic acid condensed with 2 Hol 3-nitrobenzenesulfochloride, the product he obtained is reduced to the diamino compound and the latter combined with 2 Hol 1,2,4-trichlorobenzene-5-sulfochloride. Der so erhältliche ungefärbte Endstoff, der sich beispielsweise als Natrium- oder Ammoniumsalz leicht in Wasser löst, kann als Reservierungsmittel 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 sodium or ammonium salt, for example, can be used as a reservation agent, as it has the property to a large extent of protecting wool and silk in mixed fabrics from being stained with noun dyes.
