多方法制备乙酰苯胺,培养学生的创新力

Syntheses of Acetanilide by Versatile Experimental MeansCultivate Students’ Innovation Abilitiy to Cultivate

  • 摘要: 开放实验对于提高学生的实验技能,培养学生的创新能力具有重要作用。对文献中的乙酰苯胺合成方法进行分析和比较,设计并实践了五种合成乙酰苯胺的实验方案,探讨了五种方案的实施及效果。结果表明,回流-干燥法和微波法具有操作简便、绿色,且反应时间短、产率高等优点,是较佳的乙酰苯胺实验室制备方法。

     

    Abstract: Open experiments play an important role in integrating student’s experimental skills, and in promoting student’s innovation ability. After analysis and comparison of reported synthesis methods of acetanilide, five experimental methods are designed and realized, practice and results are discussed. The results indicate that the reflux-drying method and microwave method are better for laboratory synthesis acetanilide because their advantages in simplifying and greening procedure, shorting reaction time and improving yield.
