Uses
Violanthrone (CAS NO.116-71-2) is mainly used for dyeing cotton fibers, affinity is good, color fast, leveling medium. It is less used in printing, colors are more for the fight. It can be used silk, viscose fiber, sticky cotton and cotton dyed-dimensional, but also for the polyester-cotton blend fabrics dyed with disperse dye bath melt, but also for the preparation of organic pigments.
Production
Violanthrone (CAS NO.116-71-2) is based around benzanthrone as raw material, refined naphthalene medium using potassium hydroxide and sodium acetate alkali fusion and condensation, through the recovery of naphthalene was conducted after the deal was finished refined
