| uses | is a dye intermediate, used in the preparation of anthraquinone type disperse dyes, acid dyes and vat dyes, such as Disperse Blue 2BLN and acid anthraquinone Blue and other dye intermediates. For the production of anthraquinone-type disperse dyes and acid dyes, such as Disperse Blue 2BLN and acid anthraquinone sky blue. |
| production method | with anthraquinone as raw material, step by step sulfonation in the presence of mercury sulfate, 5-disulfonic acid and 1,8-disulfonic acid, the resulting sulfonates were diluted with sulfuric acid and separated using the difference in solubility in sulfuric acid. Example of operation in the sulfonated pot, KG of anthraquinone and 34% fuming sulfuric acid 630kg (containing of metallic mercury) were added and heated to 120-125 ° C. For 4 hours. After completion of the incubation, the temperature was lowered to 100 ° C., and 96% sulfuric acid was added. After the addition, the material was pressed into a glass-lined pan. 78% sulfuric acid was added at 75 ° C., and the addition was completed in 1H. The temperature was cooled to 55 ° C. Within 4H, and the heat was maintained for 1H to completely precipitate anthraquinone -1, 5-disulfonic acid. After filtration, the filter cake was washed twice with 78% sulfuric acid 240L. The filter cake is the finished anthraquinone -1, 5-disulfonic acid. The filtrate and washings were combined for production of anthraquinone 1, 8-disulfonic acid. Raw material consumption quota: anthraquinone (98%)1498kg/t, sulfuric acid (65%)1206kg/t, fuming sulfuric acid (SO 320%)2407kg/t. |
