绿色有机合成的实验教学改革探索

Exploration on Experimental Teaching Reform of Green Organic Synthesis

摘要: 有机合成对环境污染尤为凸出，其基础有机合成实验教学的改革就显得非常重要；根据实践教学中所出现的环境污染问题，采用绿色催化剂、溶剂、氧化剂、减少原料用量、回收溶剂、催化剂回收活化再利用、产生的酸碱溶液处理重复利用、废气吸收再利用等方法来实现绿色有机合成。实践教学过程中利用这些措施，减少了原料的用量，降低了成本，同时减少了对环境的污染。实践证明，教学效果与传统实验教学一样，能达到锻炼学生实验能力的效果，增强了学生的环境保护意识，提高了教学质量。

Abstract: Organic synthesis is particularly polluting to the environment, so the reform of basic organic synthesis experiment teaching is very important. It is proposed that, in organic chemistry synthesis according to the environmental pollution problems that appear in practical teaching, green catalysts, solvents, oxidants, raw material usage, recycled solvent recycling, and catalyst recycling are used in the experimental teaching process. The importance of greenization of organic chemistry experiments is achieved by methods such as reactivation of reuse, reuse of generated acid and alkali solutions, and absorption and reuse of exhaust gas. The use of these measures in the practice teaching process not only reduces the amount of raw materials, saves costs, but also reduces the environmental pollution. Practice has proved that the teaching effect is the same as traditional experimental teaching and can achieve the effect of training students’ experimental ability. It was proved that these new educational measures had effects on improving the ability of students and the quality of education.
