• 製造方法

  To?133 parts of ?N-(2,5-dinitrophenyl)acetamide?and 93 parts of?Phthalic anhydride?added previously melted (at 95 ℃) in 280 parts of sodium and 94 parts of sulfur crystals in and salt, this melt was heated to 130 ℃, for 10 to 11 hours. Then quickly heated to 180 ℃, heat 3 to 4 hours, until the dye detection satisfaction (BIOS 1155,33).

• Properties and Applications

  yellow. Straw yellow powder. Insoluble in water, in the Sodium sulfide solution solubility is very good, for yellow. Sodium hypochlorite solution dyeing content in the part fade, in concentrated sulfuric acid for dark orange..
