Additional patent to main patent No. 217234. Process for the preparation of a stilbene dye. The present patent relates to a process for the production of a stilbene dye, characterized in that a mixture of 4-amino-2,5-dimethoxy-2'-oxy-1,1'-azobenzene-5'-sulfonic acid is used , for example prepared by coupling diazo-tated 2-amino-1-oxybenzene-4-sulfonic acid with 1-amino-2,5-dimethoxybenz (> 1, and of 4-amino-'2) -met'hoxy-1 ,
1'-azobenzo <B> '</B> 1-4-sulfonic acid, for example produced by coupling diazotized 1-aminobenzene-4-sulfonic acid with m-auisidine, with or without pressure at 4.4' -Dinitrostillben-2,2'-disulfonic acid condenses and the condensation product with copper-releasing agents in the copper lacquer.
The new dye is a dark powder when dried; it dissolves in water with brown, in conc. Sulfuric acid with violet color and dyes cotton in light, real brown tones.
<I> Example: </I> <B> 32.3 </B> parts of the dye it, represented by coupling diazotized 2-an'iino-l- o2 ## vbenzene-4-sulfonic acid with 1-amino 2,5-dimethoxybenzene, and <B> 30.7 </B> parts of the dye, prepared by coupling diazotized 1-aminobenzene-4-sulfonic acid with m-anisidine, are 47.4 parts of 4 , 4-dinitrostilbene-2,2'-disulphonic acid sodium in <B> 500 </B> parts of water and <B> 100 </B> parts of sodium hydroxide solution of <B> 36 '</B> B6 <B> 1.8 < / B> hours condensed at boiling temperature.
After the sodium hydroxide solution has been blunted with hydrochloric acid, the dye is extracted and filtered.
The still moist filter cake is dissolved in about <B> 1500 </B> parts of water at <B> 80 '</B> and mixed with an ammoniacal copper sulate solution, made from <B> 25 </B> parts of crystalline. Copper sulphate, dissolved in <B> 100 </B> parts of water and <B> 60 </B> parts of 25% ammonia, 12 hours at <B> 90 </B> to <B> 95 '</ B> stirred. It is checked that there is an excess of copper right up to the end. The copper compound is salted out and filtered.
The new dye is a dark powder when dried, it dissolves in water with brown-er, in conc. Sulfuric acid with a purple color and dyes cotton in light, real brown tones.
