高分子材料与工程专业有机化学实验改革——以丙烯酸丁酯的制备为例

Reform of Organic Chemistry Experiment in the Polymer Materials and Engineering Specialty with Example of Butyl Acrylate Preparation

结合高分子材料与工程专业的特点,在有机化学实验教学中设计并实施了丙烯酸丁酯制备实验。首先让学生查阅资料,对乙酸异戊酯制备和丙烯酸丁酯制备实验中的催化剂、反应条件、原料和产物性质等内容进行比较分析,并设计初步的实验方案;然后在具体教学实施时通过考察催化剂、反应温度和反应时间的变化,让学生分析这些因素对丙烯酸丁酯产率的影响趋势;最后让学生撰写出基于课外拓展的实验报告内容。整个实验的设计与安排有助于学生初步了解科学研究的方法,提高学生分析问题解决问题的能力,并提高学生的创新能力和实践能力。

The preparation of butyl acrylate was designed and implemented in the organic chemistry experiment which was combined the characteristics of polymer materials and engineering specialty.Firstly,the preliminary experiment scheme was designed by students through reviewing literature in which the catalysts,reaction conditions,properties of raw materials and products were compared and analyzed.Secondly,the influence of catalyst,reaction temperature and reaction time on the yield of butyl acrylate were investigated by students in the experimental teaching stage,in which variation trend of yield of butyl acrylate was analyzed and summarized by students.Finally,the experiment report was written based on experimental results and extracurricular development.The design and arrangement of this experiment are helpful for students to realize basic scientific research methods,enhance their ability to analyze and solve problems,and improve their innovative ability and practical ability.
