Vat Green 8 Usage And Synthesis

Preparation

1-Aminoanthracene-9,10-dione and 1,4,5,8-Tetrachloroanthracene-9,10-dione?in 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- 2,2' : 3,2' : 6,2''' : 7,2''''-carbazole is prepared from the corresponding pentanthrimide with aluminum chloride or with aluminum chloride–sodium chloride , .

Properties and Applications

Olive green. Black powder. Insoluble in water, alcohol and organic solvents. The concentrated sulfuric acid is dark brown, olive green after dilution with precipitation; hydrosulfite in alkaline solution, light brown red; hydrosulfite in an acidic solution of olive color. Mainly used for dyeing cotton fiber. Applies to vat olive green b or brilliant green FPB fight with grass green, khaki, but also suitable for knitwear, yarn, cotton and polyester / cotton blended fabric dyeing. Printing less effective.
