2-[benzenesulfonyl-(4-nitrophenyl)amino]-N-(2,4-dimethylpentan-3-yl)ac etamide Chemische Eigenschaften,Einsatz,Produktion Methoden

synthetische

the molecular than 2-Amino-5-(4-nitroanilino)benzenesulfonic acid, 3-(Ethyl(phenyl)amino)methyl)benzenesulfonic acid, 2-Aminobenzenesulfonic acid with heavy chromium acid potassium and sulfuric acid oxidation, then use 4-Aminobenzenesulfonic acid further oxidation, reduction with the iron powder.

Synthese

Neutral solutions containing the sodium salt of 61 kg of 4-nitro-4- aminodiphenylamine-2-sulfonic acid in 500 L ofwater and the sodium salt of 57 kg of N-ethyl- N-benzylanilinesulfonic acid in 300 L water are combined in a 5000 L wooden vat equipped with a propeller stirrer. After the solution has been diluted with 1400 L of ice water, a solution containing 75.5 kg of sodium dichromate and 37.2 kg of sulfuric acid monohydrate in 4000 L water is added at 5 ℃. After stirring the mixture for 15 min, a neutral solution containing the sodium salt of 30.5 kg of aniline-4-sulfonic acid in 290 L of water is added. The mixture is again stirred for 15 min, then heated to 40 ℃ and stirred for 15 min. After rapid heating of the mixture to 80 ℃ with live steam, 11 kg of sodium carbonate is added. The reaction mixture, cooled to 70 ℃, is transferred to a 6000 L reduction vessel equipped with a propeller stirrer, mixed with 50 kg of iron filings, and stirred for 45 – 60 min. The alkaline spot test must show a brown rather a reddish blue spot. The reaction mixture is allowed to settle, then filtered through a filter press. The process of settling and filtration is repeated and the press is then washed, first with 1000 and then with 2000 L of water. The filtrate is salted out with 800 – 850 kg of common salt and, after stirring overnight at 18 – 20 ℃, filtered under suction. After drying under vacuum, 180 – 190 kg of the dye is obtained, corresponding to 360 – 380 kg of commercial-type Acid Cyanine BF.

Properties and Applications

red light navy blue. Soluble in cold water, hot water, ethanol to blue. The strong sulfuric acid for green, diluted into blue to red light purple. In aqueous solution for the navy blue join sodium hydroxide, and precipitation.
