在有机化学实验教材及高级中学化学课本中,银镜实验一般都是水浴加热,并要在有较大试剂量的条件下才能反应,且操作比较麻烦。本文提出的一种少剂量,不需加热,现象明显,操作简便的银镜实验。1 改进后的银镜实验 1.试管的处理 在以往的银镜反应中,试管的净化处理极重要,而且处理步骤繁琐。而本方法中试管处
In organic chemistry experiment textbooks and high school chemistry textbooks, the silver mirror experiment is generally heated by a water bath, and the reaction can only be performed under conditions with a large amount of reagents, and the operation is troublesome. This article proposes a silver mirror experiment with low dosage, no heating, obvious phenomena and easy operation. 1 Improved Silver Mirror Experiment 1. Treatment of Test Tubes In the conventional silver mirror reaction, purification of test tubes was extremely important and the processing steps were cumbersome. Whereas in the test tube
