Exciting developments in the field of Green Chemistry spur the continuous innovation of experiments in the teaching laboratory. Beyond learning practical techniques, students can critically assess experiments using relevant metrics to propose further improvements and identify the most important interconnected impacts of these alternative products and processes. Herein we review popular laboratory experiments through the simple framework of feedstocks, processes, and products, offering data-driven methods for student evaluation of experiments used in the teaching laboratory. These evaluations employ techniques from life-cycle assessments and techno-economic analyses leveraging freely available data from online databases and safety data sheets. These methods may be used by students and educators to first assess seemingly distinct facets of a chemical transformation (energy inputs, reagent toxicity, etc.) and then relate these to meaningfully address system-wide improvements (replacing harmful solvents, reducing reagent costs, etc.).

在教学实验室中评估原料,过程和产品:学生使用度量标准设计绿色化学实验的框架

绿色化学领域的激动人心的发展刺激了教学实验室中实验的不断创新。除了学习实用的技术外,学生还可以使用相关的指标来批判性地评估实验,以提出进一步的改进,并确定这些替代产品和过程的最重要的相互联系的影响。在这里,我们通过简单的原料,工艺和产品框架来回顾流行的实验室实验,为学生评估教学实验室中使用的实验提供了数据驱动的方法。这些评估利用了生命周期评估和技术经济分析中的技术,并利用了在线数据库和安全数据表中的免费可用数据。
