摘 要:“致广大而尽精微”是成事之道。常压蒸馏是有机化学实验的基本操作。在文献的查询过程中发现,无论教材还是文章,对常压蒸馏的一些操作细节都没有进行深入的讨论。很多学生,包括部分教师对蒸馏操作的细节都存在误区。根据多年的有机合成实践经验,对从仪器的安装、使用方法到蒸馏操作全过程中的细节和常犯的错误进行详细的解析,与同行共同探讨,使学生快速掌握蒸馏操作技巧。The devil is in the details.Although atmospheric distillation is a basic purification technique in organic chemistry,a literature search on the subject revealed that many practical details of the process are not explained in depth,whether in textbooks or articles.As a result,many students and even some teachers harbor misconceptions about distillation techniques.Based on knowledge acquired from years of practical experience in organic synthesis,this paper presents these missing details as well as common mistakes encountered throughout the distillation process,from the setup and use of the lab equipment to the distillation itself.It is hoped that this paper will facilitate fruitful discussions with peers and help students master distillation in the lab.
