Green Chemistry: Characterization of Optically-Active Compounds as a Means for Introducing Chemistry, Nursing, and Non-Science Majors to Environmentally-Benign Laboratory Methods

化学(12)该项目将自动旋光仪集成到护理专业的有机化学、生物化学、有机和生物化学、研究型普通化学实验室、非理科专业的化学和本科研究等课程中。来自标准研究和工业文献的实验正在被改编。这一整合的目的有三个：促进学生对绿色化学的认识和参与，或以经济上负责任的方式减少对环境的不利影响，促进学生对立体化学概念的理解，并增加学生接触工业和学术研究实验室使用的现代仪器。这些目的与正在进行的全机构科学课程改革项目的目标相辅相成。旋光仪与其他仪器一起使用来表征光学活性产品。这个项目的目标是训练学生在废物形成之前消除它们，使用水作为反应介质，改用可生物降解和无毒的试剂，用催化替代品取代化学计量方法，并将立体化学理解为一种分类方案。后一项目标属于NSF资助的校园课程改革基金的范畴，该基金已经在进行中，并将在2000年出版一本适用于非理科专业的模块实验室手册。每年有超过100名学生受到这个项目的影响。

Chemistry (12)The project integrates an automatic polarimeter into courses including Organic Chemistry, Biochemistry, Organic and Biochemistry for nursing majors, research-oriented General Chemistry laboratory, Chemistry for non-science majors, and undergraduate research. Experiments from standard research and industrial literature are being adapted. The purpose of this integration is three-fold: to promote student awareness of and participation in green chemistry, or the reduction of adverse environmental impact in an economically responsible manner, to facilitate student understanding of stereochemical concepts, and to increase student exposure to modern instrumentation that is used in industrial and academic research laboratories. These purposes complement the goals of an ongoing Institution-Wide Curriculum Reform Project in science. The polarimeter is used in combination with other instruments to characterize optically-active products. The objectives of this project are to train students to eliminate waste proejcts before they form, use water as a reaction medium, switch to biodegradable and non-toxic reagents, replace stoichiometric methods with catalytic alternatives, and understand stereochemistry as a classification scheme. This latter objective falls under the rubric of a campus-wide NSF-supported curriculum reform grant that is already underway and will culminate in the year 2000 with the publication of a laboratory manual of modules suitable for nonscience majors. Over 100 students per year are impacted by this project.
