大專(高中)有機化學實驗微量化的可行性初探

A Preliminary Assessment of Introducing the Microscale Approach in the Organic Laboratory

摘要


微量化的實驗,有很多優點,不但化學藥品用量減低10倍以上,蒸餾純化時,費時縮短3~7倍,所需空間減小,更重要的,廢物量減低而保護環境。本文針對有機化學實驗,探討實施微量化的可行及不可行之處,學習效果,及對學生心理的影響。

The microscale approach in organic chemistry experiments has many advantages; not only are amounts of reagents reduced by at least ten times and the distillation time shortened by three to seven times, but more importantly, chemical wastes are qreatly diminished, thus helping to protect our environment. This article discusses the feasibility of the microscale approach in the organic chemistry laboratory, its effect on students' learning, and the matter of their preference.
