Green Chemistry

Abstract
One principle of green chemistry is the elimination of waste in chemical processes prior to its generation. For this dry laboratory, a procedure for the nitrosation of 2,5-hexanedione is evaluated using a recently described metrics system. Since the reaction conditions for the synthesis of 3-acetyl-5-methylisoxazole are solvent-free and the process utilizes catalytic chemistry, this experiment concentrates on an analysis of the impact of auxiliary substances such as extraction solvents and separation agents as sources of waste in chemical processes. The importance of yield improvement as it relates to waste minimization is also highlighted.
Supplement
Uses and other preparations for 3-acetyl-5-methylisoxazole, the procedure for the environmental-impact analysis, and student exercises are available.
