摘要
化学实验“从大豆中提取豆油”,原方法和装置不易操作,造成实验成功率低,且存在氯仿污染环境的问题。针对这一问题进行了改进,改进后的实验,学生易操作,重复性好,无污染,还能准确地测定豆油的含量。
The traditional chemistry experiment of extracting bean oil from soybean has many disadvantages. For example, the method and equipment are not easy to operate, success rate is low, and chloroform pollutes environment. In order to solve these problems, we improve the experiment. The new devised method is convenient for students to operate. It also has merits such as good repeatability, no pollution. Furthermore, it can measure the precise content of bean oil.
