<I>Beispiel:</I> Die einem Grammolekül entsprechende Menge Bis-(3-aminobenzol- 1-sulfonyl-3'-amino- benzol-1'-sulfonyl-)-4", 4"'-diaminostilben-2", 2"'-disulfosäure wird am Rührwerk in etwa 8 Liter heisses Wasser eingetragen und durch allmähliche Zugabe von 110=120 gr Soda neutral in Lösung gebracht. In die gut ver rührte Lösung trägt man dann bei-85-90' etwa 150 gr Schlämmkreide und 532 gr 3 Nitrobenzolsulfochlorid ein.
Die Kondensation beginnt nach kurzer Zeit vor sich zu gehen, und man erhält nach Beendigung des Schäu- mens eine neutral reagierende, nur noch in Spuren diazotierbare, beim Erkalten milchig sieh trübende Lösung. Die Reaktionslösung wird noch etwa 1/2 Stunde bei 90-95 ge halten und dann mit roher Salzsäure schwach angesäuert, wobei ein Teil des Kondensa tionsproduktes sich schon in der Wärme in öliger Form ausscheidet.
Die noch etwa 85 warme Emulsion lässt man dann auf eine gut verrührte, schwach angesäuerte Anschläm- mung von etwa 750 gr Eisenmehl in 90 warmem Wasser fliessen. Die Reduktionsmi schung wird etwa 3-4 Stunden bei 90-99 gehalten, bis in der Anachlämmung keine zähflüssigen Bestandteile mehr vorhanden sind, dann mit Natronlauge stark alkalisch gemacht und heiss abgesaugt.

Das auf der Nutsche gewaschene und getrocknete Produkt stellt ein fast farbloses Pulver dar, das sich sodaalkalisch hell in warmem Was ser löst und beim Diazotieren eine in kaltem Wasser schwer lösliche, schwach gelblich gefärbte Tetrazoverbindung bildet.

Process 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 that can be used, for example, as a reservation agent for wool or silk against staining with substantive dyes, if one 1 1VIo1. the one after the Swiss.
U.S. Patent No. 153372 presentable bis (3-aminobenzene-1-sulfonyl-3'-aminobenzene-1'-sulfonyl -) - 4 ", 4" '- diaminostilbene-2 ", 2"' - disulfonic acid with 2 moles. 3 -Nitrobenzenesulfochloride condenses, which he obtained condensation product reduced to the diamino compound and this with 2 1bIol. 1,2-dichlorobenzene-4-sulfochloride combined.
<I> Example: </I> The amount of bis (3-aminobenzene-1-sulfonyl-3'-aminobenzene-1'-sulfonyl-) - 4 ", 4" '- diaminostilbene-2 "corresponding to one gram molecule 2 "'- disulfonic acid is introduced into about 8 liters of hot water on the stirrer and brought into neutral solution by gradually adding 110 = 120 g of soda. In the well-stirred solution you then wear at -85-90 'about 150 grams of white chalk and 532 grams of 3 nitrobenzenesulfochloride.
The condensation begins to take place after a short time, and after the foaming has ended, a solution which reacts neutrally, can only be diazotized in traces and appears milky when it cools, is obtained. The reaction solution is kept at 90-95 ge for about 1/2 hour and then weakly acidified with crude hydrochloric acid, with part of the condensation product already separating out in the warmth in oily form.
The emulsion, which is still about 85 grams warm, is then allowed to flow onto a well-stirred, slightly acidified slurry of about 750 grams of iron flour in 90 grams of warm water. The reduction mixture is kept at 90-99 for about 3-4 hours until there are no more viscous components in the slurry, then made strongly alkaline with caustic soda and vacuumed hot.
The result is a pale yellowish clear broth which is allowed to flow onto excess crude hydrochloric acid diluted with water, the reduction product, the bis (3-ami- 3 "-amirrobenzene-1" -sulfonyl -) -4 "'; 4" "- diamino-stilbene-2"', 2 "" - disulfonic acid of the formula

The product, washed and dried on the suction filter, is an almost colorless powder that dissolves in a light soda-alkaline solution in warm water and, when diazotized, forms a slightly yellowish tetrazo compound that is sparingly soluble in cold water.
The amount of this product corresponding to one gram cooler is poured into about 16 liters of hot water on the agitator and brought into a slightly alkaline solution by gradually adding 130 grams of soda. About 160 grams of whiting chalk is added and 614 grams of 1,2-dichlorobenzene-4-sulfochloride are added at 8b-90 with thorough stirring.
After a while, the reaction sets in with vigorous foaming of the mixture, and the reduction product "separates out in the form of a viscous, gradually thinning oil on the walls of the reaction vessel and on the surface of the liquid.
