依据原子利用率、环境因子和“5R”原则（包括“减量”、“循环使用”、“回收”、“再生”及“拒用”）来设计二氧化硫（ SO2）的制取及性质实验（包括SO2的溶解性、水溶液的酸性、还原性及其氧化性），做到实验药品的减量化、无污染，实现环境友好。此实验的改进，不仅操作简便快捷，而且现象明显，有助于巩固和加深学生绿色化学知识。

On the basis of atom utilization, environmental factors, and the 5R principles including the Reduciton , Reuse , Recycling , Regeneration and Rejection , the preparation and properties experiments , such as water solubility , acidity of water solution , reducibility and oxidisability of SO 2 of sulfur dioxide ( SO2 ) were designed to reduce drug usage and avoid harming environment and people.After improvement of the experiment , it was not only convenient to operate but also to observe the experimental phenomenon , which could help students consolidating and deepening the knowledge about the green chemistry.
