关于1-溴丁烷制备实验的一些探讨

摘要

The synthesis of 1-bromobutane is one of the most important basic organic experiments in universities . Some problems and defects of traditional procedure of this experiment were found and the reasons were discussed . Here the modification , which simplifies the procedure and improves the reaction efficiency are reported .%1-溴丁烷的制备是基础有机化学实验的重要内容。本文对学生在该实验中常出现的问题进行系统的分析，并提出了相应的改进方法，即利用乙醚萃取的方法替代蒸馏方法提取1-溴丁烷粗产品。本方法克服了蒸馏末期产品容易碳化的弊端，简化了实验过程，提高了收率，具有明显的优越性。
