Vat Orange 9 Usage And Synthesis

Preparation

8,16-Pyranthrenedione called. (a) 1-(2-Methyl-9,10-dioxoanthracene-1-yl)-2-methylanthracene-9,10-dione in 350 ~ 380 ℃ heat alone, or in low temperature with dehydrant processing, take off 2 Moore water; (b) 1-(2-Methyl-9,10-dioxoanthracene-1-yl)-2-methylanthracene-9,10-dione?aqueous cream content (with or without ammonia or salt all but), in 230 ~ 250 ℃ and under pressure heating 10 to 12 hours; (C) 1-(2-Methyl-9,10-dioxoanthracene-1-yl)-2-methylanthracene-9,10-dione?and Etanol/Potassium hydroxide heating 10 to 12 hours; (d) 1,6-Dibenzoylpyrene?with Aluminium chloride and Sodium chloride melting, and access to oxygen.

Properties and Applications

yellow orange. Orange powder. Soluble in 1, 2, 3, 4-Tetrahydronaphthalene and Xylene, slightly soluble in alcohol. In the dark for the strong sulfuric acid, dilute yellow brown after precipitation. Alkaline reduction for blue-ray red body hidden color; Acid reduction to orange color body hidden. This product for light brittle dye, cotton fiber in the sunlight has accelerated. With light brittle, general is not used for cotton cloth of monochromatic dyeing, spelling color also should control consumption, but also can directly printing and the discharge, also can be used in viscose, silk dyeing. Dye polyester/cotton blended fabric, of polyester dyeing serious.
