绿色化学实验是在绿色化学思想的指导下,用预防化学污染的新思想、新技术和新方法,对常规的实验进行改革。在绿色化学实验的研究中,我们对“氯气与金属铜的反应”这个污染较严重的传统实验进行了绿色化设计与实践,并在实践中取得了理想的效果。一、问题的提出在新教材高中第一册第四章《卤素》实验(4—1)中:把灼热的铜丝放入充满氯气的集气瓶中,观察发生的现象,此时铜丝会剧烈燃烧,使集气瓶里充满棕黄色的烟,注入少量水后得到黄绿色的液体。此实验效果很明显,一般的教师都喜欢看到这个结果。但由于此实验在半敞开的集气瓶中进行,因而当实验成功之时,氯气也已经弥漫在整个教室,造成了环境污染,直接影响到每个学生的身体健康。所以好多教师又都很怕做这个实验。因而,对这一实验装置和操作过 Under the guidance of the green chemistry thought, the green chemical experiment is to reform the conventional experiment with new ideas, new technologies and new methods to prevent chemical pollution. In the research of green chemistry experiment, we designed and practiced the green experiment of “the reaction of chlorine and metal copper”, which is more serious pollution, and achieved the ideal effect in practice. First, the problem raised In the new textbook in the first volume of the fourth chapter “Halogen” experiment (4-1): the hot copper wire into a gas-filled bottle, observe the phenomenon occurs, this time the copper wire Will be violently burned, so that the collection of bottles full of brown smoke, a small amount of water into the yellow-green liquid. The experimental effect is obvious, the average teacher likes to see this result. However, since the experiment was conducted in a semi-open gas cylinder, when the experiment was successful, chlorine gas was already diffused throughout the classroom, causing environmental pollution and directly affecting the health of each student. So many teachers are afraid to do this experiment. Therefore, this experimental device and operation
