Name: disperse turquoise blue s-gl; Also known as: disperse lake blue s-3gl; C.I.D isperse Blue 60
Molecular formula: C20H17N3O5 molecular weight: 379.37 CAS number: 12217-80-0
Property: blue black powder. Insoluble in water, slightly soluble in ethanol, soluble in pyridine, acetone and methylamide.
Preparation methods: there are two synthesis methods: 1.1, 4-diaminoanthraquinone -2, 3-dicarboxylic anhydride and methoxypropylamine condensation. 2.1, 4-diamino-anthraquinone -2, 3-diformimide method 1, 4-diamino-2, 3-dichloroanthraquinone was prepared from 1, 4-diamino-2, 3-dichloroanthraquinone by sulfanation and cyanidation, and then reacted in concentrated sulfuric acid at 150℃ for 1h. The closed loop is 1, 4-diamino-2, 3-diformimide, and then in the high boiling point organic solution, condensate with -methoxypropylamine at 175-200℃ to obtain the original dye.
Application: mainly used for dyeing and printing of polyester and its blended fabrics. This product is yellowish green, in addition to use alone, but also spell out a series of color spectrum from brilliant blue to yellowish green. It can also be used for dyeing acetic acid fiber (normal temperature method), triacetic acid fiber (normal temperature carrier method and high temperature and high pressure method). The lifting power of printing acetate fiber is higher than dyeing.
