English name: Anthraquinone 
CAS No.: 84-65-1 
Molecular formula: C14H8O2 
Molecular weight: 208.2121 
Content: 98% 
Physicochemical properties: 
Properties: mostly yellow or orange crystal, with a certain melting point. Solubility: Soluble in organic solvents such as benzene, ether, chloroform, ethyl acetate, etc., slightly soluble or insoluble in water. Sublimation: heating under normal pressure can sublimate. Fluorescence: Most of the terpenoids and their glycosides are fluorescent and show different fluorescence under different pH conditions. Acidity: The phenolic hydroxyl group in the terpenoid is related to the number and position of the phenolic hydroxyl group. It is not easily oxidized and can undergo nitrification, sulfonation and bromination reactions.

Uses:
Organic synthesis of intermediate dyeing intermediates, such as indanthrene vat dyes, acid dyes, and some active dyes. It can be used as a papermaking digester and a hydrogen peroxide raw material to reduce the amount of alkali used and shorten the cooking time. Used as a papermaking pulp cooking agent, only a small amount of hydrazine can be added to the alkali cooking liquor to accelerate the speed of delignification, shorten the cooking time, increase the pulp yield and reduce the waste liquid load. There are more and more paper mills currently using antimony additives.
