use | as chelating extractant. |
production method | p-carbamol hydrochloride, glycerin, sulfuric acid and picric acid are mixed evenly and heated for 3-4h. Dilute with water to make it weakly alkaline. Then use acetic acid to adjust to strong acidity. Finally, steam distillation is used, ammonium hydroxide is added to precipitate the crude product from the acetic acid distillate, and the finished product is obtained by recrystallization and purification with ethanol. |
