| titleOfInvention | A kind of post-processing method for preparing chromophane AS-PH |
| abstract | The invention belongs to the technical field of chemical industry, and in particular relates to a post-processing method for preparing chromophan AS-PH. In the invention, the reaction solution after synthesizing chromophan AS-PH is desolvated and cooled, and then stirred and washed with anhydrous ethanol in turn, Rinse and dry to obtain refined chromophore AS-PH. The present invention abandons the traditional treatment methods such as alkali-soluble acidification, has simple treatment process and strong operability, and solves the problem of low product purity, high content of alkali-insoluble matter, and catalyst problems caused by the mechanical application of the traditional process chromophenol AS-PH mother liquor. Due to technical difficulties such as recovery and application, the product purity can reach more than 99.5%, the alkali-insoluble content is less than 0.08%, the alkali-insoluble content is greatly reduced, and the color of the product is light brown, which meets the market demand for high-purity color phenol AS-PH. |
