Anthraquinone function 

Anthraquinone most used in dye, but the amount of fertilizer used for pulp making steamed solution has been a rapid increase

(1) is used in the production of the dye by anthraquinone as raw material, the sulfonated nitrification chloride, etc., can get a wide range of dye intermediates, used in the production of anthraquinone disperse dye the acid dye VAT dye reactive dyes, such as formation of chromatographic performance good dye all categories according to the statistics, anthraquinone dyes has more than four hundred varieties, occupies very important position in the field of synthetic dyes

(2) used as papermaking pulping cooking agent in alkaline cooking liquor simply add a small amount of anthraquinone, can accelerate the speed of lignin, shorten the cooking time, improve the pulp yield, reduce the waste liquid load currently used more and more anthraquinone anthraquinone additives paper mill as cooking additive consumption growth quickly anthraquinone and other application fields of anthraquinone compounds can be used in the production of high concentrations of hydrogen peroxide.In the fertilizer industry, it is used to make desulfurizing agent anthraquinone sodium disulfonate in the printing and dyeing industry as the discharge agent

(3) which can be used as the pulping agent for pulping of papermaking, which can reduce the amount of alkali and shorten the cooking time.
