Molecular Structure: amino-naphtho quinone class
Molecular Weight: 345.97
CAS Registry Number: 12222-76-3
Manufacturing Methods :
Properties and Applications: bright blue. Navy powder. Slightly soluble in benzene and carbon tetrachloride, soluble in acetone, ethanol, ethyl glycol. The strong sulfuric acid for light brown olivaceous, diluted to blue. In dye bath of copper, iron ion in light of a certain effect. Dyeing appropriate pH value for 5 ~ 6. The dyes melt method of solid color rate is very low, it is hard to be dyed dark, can only be used for lake blue.Used for dyeing acetate fiber, can be obtained green cobalt blue, even dye rate, dye deep sex are better. Dyed dark, wet process fastness is poorer. Dyed fiber can get three vinegar blue-green light, high temperature and high pressure to dye the dark staining. The dyes can be used for polyester fiber fabric and vinegar direct printing.
