Blue colorants comprising a chromophore having at least one poly(oxyalkylene) chain attached to the 1- position, the 4- position, or both, through aromatic amino group or groups, of an anthraquinone backbone are provided. Such colorants exhibit excellent amine / base stability and thermal stability, effective colorations, excellent low extraction rates, and high lightfastness levels, particularly when incorporated within certain media and / or on the surface of certain substrates, particularly polyesters, polyolefins, and polyurethanes. The poly(oxyalkylene) chain or chains can be conveniently tailored to increase the solubility or compatibility in different solvents or resins thereby permitting the introduction of such excellent coloring chromophores within diverse media and / or or diverse substrates as well as provides a liquid colorant which facilitates handling. Compositions and articles comprising such colorants are provided as well as methods for producing such inventive colorants.

Red colorants comprising a chromophore having at least one poly(oxyalkylene) chain attached to the 1-position, as well as at least one poly(oxyalkylene) chain attached to either the 5-position or the 8-position of an anthraquinone backbone are provided. Such colorants exhibit excellent base stability, effective colorations, excellent low extraction rates, and high lightfastness levels, particularly when incorporated within certain media and / or on the surface of certain substrates, particularly polyesters. The poly(oxyalkylene) chains also increase the solubility in different solvents or resins thereby permitting the introduction of such excellent coloring chromophores within diverse media and / or diverse substrates as well as provides a liquid colorant which facilitates handling. Compositions and articles comprising such colorants are provided as well as methods for producing such inventive colorants are also provided.

The invention provides a synthesis method, a derivative and a battery system of an anthraquinone derivative containing a carboxyl group. The synthesis method of the anthraquinone derivative containingthe carboxyl group includes the following steps that S1, dibasic acid containing a terminal carboxyl group and sulfoxide chloride are mixed, toluene is added as a reaction solvent, a catalyst is added, and heated to a set temperature reaction; S2, after the reaction is completed, the solvent and the sulfoxide chloride are removed, the toluene is added for distillation, and a reactant is obtained;S3, the reactant is mixed with amino-anthraquinone, the toluene is added as the reaction solvent, and heating is conducted to a reflux reaction; and S4, after the reaction is completed, the solvent is removed, solids are filtered and removed, the pH value of a filtrate is adjusted to a predetermined value, the solids are separated out, filtered, washed and dried, and the anthraquinone derivativecontaining the carboxyl group is obtained. According to the synthesis method of the anthraquinone derivative containing the carboxyl group, simpleness is achieved, operation is easy, the cost is low,and the synthesis method can be applied to the battery system to solve the problem of electrochemical energy storage.

The invention relates to two novel substances, specifically (1R,2S,3S,4R)-3-acetoxy-1,2,4,5-tetrahydroxy-y-methoxy-2-methyl-1,2,3,4-tetrahydroanthracene-9,10-dione (3-O-acetyl-altersolanol M) (I) and 8-(4,5,6-trihydroxy-7-methyl-2-methoxy-9,10-dioxo-9H,10H-anthracene-1-yl)-(1S,2S,3R,4S)-1,2,3,4,5-pentahydroxy-7-methoxy-2-methyl-1,2,3,4-tetrahydro-9H,10H-anthracene-9,10-dione (atropisomeric alterporriol I und J), (II) to the use thereof as anti-infective agents or anti-cancer agents, and to a production method therefor.
