Naphtol AS-ITR;C.I.Azoic Coupling Component 12
Molecular formula :
MW :
CAS :

nature : homework properly known as AS-ITR. For gray or green uniform powder. 193-194 ° C melting point. Do not dissolve in water and sodium carbonate solution, pyridine-soluble, ethanol and benzene soluble in acetone. The sulfuric acid solution was yellow, and green fluorescence shows; The sodium hydroxide solution was yellow. Air stability. When the brightly-colored stain, good fastness, especially with the red-ITR supporting the use of a much better Peach was bright red, dark fiber embrittlement phenomenon. Used mainly cotton yarn, cotton fabric, viscose fiber, silk and nylon fabric dyeing and printing. With 2,3-acid as raw materials and sodium carbonate, salt-chloroaniline, dehydration, and with phosphorus trichloride, 2,4, - dimethoxy-5-chloroaniline condensation, and in Egypt, steamed after chlorobenzene obtained.
