现代生活中被遗弃的各式各样的废塑料瓶到处都能找到。收集并挑选合适的塑料瓶进行简单加工可制成反应器,在做化学实验时,既现象明显、操作简便,又安全可靠、清洁环保。现选取笔者用塑料瓶改进的一些化学实验,供同行参考。一、选材与制作选取两个大小相近的无色透明塑料瓶,分别截取塑料瓶的上下两部分,配上橡胶塞等,组成图1所示 A variety of waste plastic bottles abandoned in modern life can be found everywhere. Collection and selection of suitable plastic bottles for simple processing can be made into reactors. When doing chemical experiments, it is obvious, easy to operate, safe and reliable, clean and environmentally friendly. I have now selected some chemical experiments improved by plastic bottles for the reference of my colleagues. First, material selection and production Select two colorless transparent plastic bottles of similar size, cut the upper and lower parts of the plastic bottle respectively, coupled with a rubber stopper, etc., as shown in Figure 1.
