工业酒精是实验室常用燃料，纯度高、质量好的工业酒精能给实验带来很多方便，相反劣质工业酒精会给实验带来意想不到的麻烦，甚至影响实验课的开出．本文介绍了检验工业酒精纯度的一些简便方法，以供同仁参考．下表是对不同纯度的工业酒精实验得到的结果．由表可看出简便检验 Industrial alcohol is a commonly used fuel in the laboratory. High purity and good quality industrial alcohol can bring a lot of convenience to the experiment. On the contrary, poor quality industrial alcohol can bring unexpected troubles to the experiment and even affect the opening of experimental courses. This article describes some simple methods for testing the purity of industrial alcohol for reference by colleagues. The following table shows the results of experiments on industrial alcohols of different purity. From the table can be seen simple test
