Properties and Applications

bright purple. Dark purple powder. Soluble in ethanol, acetone, benzene. For the strong sulfuric acid in dark brown, diluted into purple. Dyeing of iron ion in color no effect, encounter copper ions have influence. Used for polyester, two vinegar fiber, three vinegar, polyamide fiber fabric such as dyeing or printing. The bright red dye polyester get purple, has the high insolation fastness, of acid-base stability. Dye bath appropriate pH value for 3 ~ 9, good levelness, dye deep sex differences, mainly used for light. Hot melt knot dyeing solid color rate is low, hot melt temperature should not exceed 190 ℃, sublimation fastness is poorer. Mainly used for polyester knitted fabric made of high temperature and high pressure, the dyeing of dyeing.

Environment-friendly and energy-saving process for synthesizing 1, 4-diamino-2, 3-dichloroanthraquinone

The invention relates to the technical field of dye intermediates, in particular to a process for synthesizing 1, 4-diamino-2, 3-dichloroanthraquinone. The process comprises the following steps: adding a certain amount of chlorobenzene serving as a solvent into a reaction container, adding a certain amount of 1, 4-diaminoanthraquinone leuco body and zinc peroxide serving as a catalyst after the moisture is detected to be qualified, heating to 40-50 DEG C, and stirring and preserving heat for 10-20 minutes; stirring and dropwise adding quantitative sulfuryl chloride under the condition of 40-50 DEG C, and preserving heat for 10-60 minutes under the condition after dropwise adding is finished; after the reaction is completed, performing vacuum pumping for 30-60 minutes, and adding sodium carbonate to adjust the pH value of the reaction liquid to be nearly neutral; and performing water vapor distillation to recover the solvent, and filtering and washing the material to obtain the product. According to the synthesis process of the 1, 4-diamino-2, 3-dichloroanthraquinone provided by the invention, the catalyst zinc peroxide is added, so that the reaction temperature can be reduced, the reaction time can be shortened, the dosage of the sulfuryl chloride can be reduced, and the synthesis process has positive significance on reducing the cost and reducing the environmental protection pressure.

REACTION OF BORATE COMPLEXES OF 1,4-DIAMINO- AND 1-AMINO-4-HYDROXYANTHRAQUINONES WITH THE ANIONS OF CH ACIDS

The reaction of the diboroacetates of 1,4-diamino- and 1-amino-4-hydroxyanthraquinones with CH acids in an aprotic polar solvent in the presence of a base leads to the angular 5-amino- and 5-hydroxynaphtoindole-6,11-diones respectively.In the reaction of the diboroacetate of 2,3-dichloro-1,4-diaminoanthraquinone with dibenzoylmethane the main reaction product is the linear 4,11-diaminoanthrafuran-5,10-dione.
