| titleOfInvention | A kind of chemical intermediate and preparation method thereof |
| abstract | A chemical intermediate and a preparation method thereof belong to the technical field of dye intermediate synthesis. This chemical intermediate provides a new way for the preparation of anthraquinone dyes and dye intermediates. The preparation method of the intermediate adopts 3-acetamidophthalic anhydride and benzene as two cheap and readily available raw materials, and studies the catalytic performance of three different catalysts, and it is found that the AlCl 3 -ZnCl 2 composite catalyst has the highest catalytic efficiency. The preparation method has mild reaction conditions, simple operation, safety and environmental protection, and high yield, and can obtain high-purity products through a simple purification method, which is suitable for industrial production. |
