| | Vat Green 8 Usage And Synthesis |
| Uses | Vat Khaki 2G (Vat Green 8) is used for dyeing cotton and silk fibers. It has good leveling properties and affinity, and is a major dye for grass green. It is also used for dyeing viscose-cotton and polyester/cotton blended fabrics. It is often blended with Vat Brown GG, BR, and Sulfur Vat Black CLN to dye various shades of brown yarns, with Vat Olive Green B to dye various shades of olive green yarns, and with Vat Olive Green B or Vat Brilliant Green FFB to dye grass green fabrics. Fabrics dyed with this product become slightly lighter in color after treatment with urea-formaldehyde or cyanoform resin. It is an important dye variety for dyeing military uniform fabrics. | | Preparation | 1-Aminoanthracene-9,10-dione and 1,4,5,8-Tetrachloroanthracene-9,10-dionein copper and Nitrobenzene under the existence of condensation,And then cyclized with aluminum chloride anthraquinone five four imine. | | Synthesis | 1,1' : 4,1'' : 5 ,1''' : 8,1''''-Pentanthrimide-
