The Study of Green Chemistry Experiment 6835 greening study







This paper makes a brief overview of organic chemistry first, and then specifically discusses the organicism of chemistry experiments in Middle School from three aspects: the use of organic chemical reagents, the organicism of catalysts and reactant. The main purpose is to let students build the concept of organic chemistry while learning chemical experiments, cultivate their good habits of doing experiments and set up the consciousness of protecting the environment.

The Study of Green Chemistry Experiment
Han Xingmei (College of life science and chemistry, Tianshui Normal University, Gansu, Tianshui 741,000) Abstract: This paper makes a brief overview of organic chemistry first, and then specifically discusses the organicism of chemistry experiments in Middle School from three aspects: the use of organic chemical reagents, the organicism of catalysts and reactant. The main purpose is to let students build the concept of organic chemistry while learning chemical experiments, cultivate their good habits of doing experiments and set up the consciousness of protecting the environment.
