Carbazole
Use purpose
It is used as an intermediate of dyes such as sulfur reduction blue Rnx, N-vinyl carbazole plastics, tetranitrocarbazole, chlorinated carbazole and other pesticides.
Carbazole is a nitrogen-containing heterocyclic compound and one of the components with the highest economic value in coal tar. 90% of Carbazole in the world is obtained from coal tar. Carbazole can be used to produce dyes, pigments, photoconductors, photosensitive materials, special inks, etc. the pigment YONGGU purple RL produced by it is widely used in the coloring of automobile topcoats and high-temperature resistant plastics. It has the advantages of high temperature resistance and ultraviolet light resistance. The dyes produced with it have excellent fastness indexes, especially the excellent fastness to chlorine bleaching. The blue varieties include carbazole IDM, carbazole LR, carbazole LB and carbazole l3b, and the black varieties include carbazole black D. It also produces carbazole dioxazine violet, a cyan pigment used in coatings, printing inks, carbon paper, etc. Carbazole is used in the production of sulfide reduction blue Rnx, direct sun resistant blue FFRL, ffgl, etc. It can be used to make leather, N-vinyl carbazole plastic, pesticide, tetranitrocarbazole and chlorinated carbazole, and can also be used to manufacture UV sensitive photographic dry films.

Most carbazole in nature comes from coal and is obtained from tar. It is one of the components of coal tar with high economic value. Carbazole has the advantages of high temperature resistance and UV resistance. It is widely used in the coloring of automotive topcoats and heat-resistant plastics. Carbazole derivatives are monomeric poly complexes with excellent thermal conductivity, conductivity, ion exchange and other physical properties. Therefore, the synthesis of carbazole and its derivatives is one of the hotspots of current research. In addition, carbazole has strong thermal stability and photochemical stability. The structure of carbazole is easy to modify and the carbazole ring is easy to form stable cations. Carbazole also has good transmission capacity and cheap raw materials. Carbazole derivatives are widely used in the field of polymer materials.
