摘　　要：液液萃取实验是化工原理课程体系的经典单元实验,在化工实验教学中占有重要的地位,同时该实验也是面向非化工专业本科生开放的化工基础实验。这样一个成熟的化工单元实验,依然存在需要改进的地方,特别是煤油的使用与处理带来的安全环境问题。探索用白油代替煤油进行萃取实验,提出对经典化工实验的改进方案。该文结合华中科技大学应用化学和化学专业的相关实验教学实践,把液液萃取实验优化成既安全又环保的化工基础实验。As a classic experimental method in the course system of chemical engineering principle,the liquid-liquid extraction experiment occupies an important position in the experimental teaching of chemical engineering.At the same time,this experiment is also a basic chemical experiment open to non-chemical undergraduates.Such a mature chemical experimental method still needs improvement,especially the safety and environmental problems caused by the use and treatment of kerosene.Exploring the use of white oil instead of kerosene in the extraction experiments,and a green improvement design was proposed for this classic chemical experiment.Combining the relevant experimental and practical results of the college’s applied chemistry and chemistry majors,the liquid-liquid extraction experiment is further developed into a safe and environment-friendly basic chemical experiment.
