绿色有机合成的教学探索

Teaching of Green Organic Synthesis

针对有机化学合成实验对环境污染问题,根据实践教学中所出现的环境污染问题提出了在有机化学合成实验的教学过程中,通过采用绿色催化剂、溶剂、氧化剂、减少原料用量、回收溶剂再利用、催化剂回收活化再利用、产生的酸碱溶液重复利用、废气吸收再利用等方法来实现有机化学实验绿色化的重要性。在实践教学过程中利用这些措施,不但减少了原料的用量,节约了成本,同时降低了对环境的污染。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。不仅如此,在提高学生能力的同时,增强了学生的环境保护意识,从而提高了教学质量。

For environmental pollution problems in organic chemical synthesis experiments, 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 have effects on improving the ability of students and the quality of education.
