Natrium-7-phenyl-5,9-bis(phenylamino)-4,10-disulfonatobenzo[a]phenazinium Chemische Eigenschaften,Einsatz,Produktion Methoden
synthetische
6,8-Bis(phenylamino)naphthalene-1-sulfonic acidand 5-Amino-2-(phenylamino)benzenesulfonic acid condensation, its product to (add) ammonia of cuprous oxide as the catalyst for air oxidation.
Synthese
Weakly basic solutions containing 0.87 kmol of 1,3-bis(phenylamino) naphthalene-8-sulfonic acid in 1700 L of water and 0.9 kmol of 4-aminodiphenylamine-2- sulfonic acid in 1000 L of water are combined in a 10000 L iron kettle equipped with a propeller stirrer (95 rpm), and a solution containing 35 kg of copper sulfate and 40 kg of 40% ammonia in 130 L water is added, followed by 40 kg of ammonium chloride and 3500 L of ethanol. After dilution to 7000 L with water, air is blown through the mixture at 40 ℃ for 6 h. Then, the reaction mixture is allowed to cool to 25 ℃ and salted out with 2000 L of 25 % common salt solution. After the mixture is filtered through a suction filter under pressure, the press cake is washed twice with cold water.
Properties and Applications
red light blue. Red light blue powder, easily soluble in water, but soluble in ethanol (for purple) and soluble fiber element, insoluble in benzene, toluene. The strong sulfuric acid dyes are green, diluted into red light blue; In nitric acid are Deep violet color. The water soluble for blue, add sodium hydroxide to red brown, precipitation; Add hydrochloric acid to purplish blue, precipitation. In dyeing iron ion turned dark colored, copper ions in the dark colored. Used for wool, silk, polyamide fiber and its blending fabric, the influential wool fabric dyeing and printing directly, can also be used for leather, nitro cellulose paint color. The heavy metal salt can be used as organic pigments used to paint.
