| titleOfInvention | Method for synthesizing acetyl dithranol |
| abstract | The invention discloses a method for synthesizing acetyl dithranol. The method comprises steps of dissolving anthralin in toluol, adding pyridine when the solution is cooled to the temperature from -5 DEG C to 4 DEG C, adding acetyl chloride after even stirring, conducting the reaction for 30-40 minutes at the temperature from -3 DEG C to 8 DEG C, and obtaining a solution containing the acetyl dithranol. The mol ratio of the acetyl chloride and the anthralin is 12.4-14.0, the use amount ratio of the anthralin and the toluol is 1g: 34-42ml, and the use amount mol ratio of the pyridine and the toluol is 12.0-14.0. Based on a prior method, the solvent is replaced, the reaction condition is optimized, the modified process line is improved, the reagent toxicity is reduced, the cost is reduced and the yield is improved compared with the yield reported by foreign documents. |
