| Abstract: | Based on the mechanism for chlorination of methane, this paper analyzed material system, reaction vessel, light conditions and experimental characterization, and then designed methane and chlorine substitution reaction. The research findings were supported in terms of experimental data collected by pressure and temperature sensors in digital experiment to explicitly characterize the "substitution" process of methane and chlorine. The research provides implications to improve the experiment of chlorination of methane. |
| Keywords: | methane substitution reaction photochemical reaction digital experiment self-made teaching materials experimental innovation design |
