How Green is My Orange? Green Extraction of Limonene using Super Critical CO 2

Phase Diagram of CO 2

What is limonene? Z(d)-(+)-R-limonene ZFound in rind of oranges and lemons ZIt is a cyclic terpene

How else is this extraction done? (non-Green method) Zhttp:// ch?v=fVZRnVKqkgwhttp:// ch?v=fVZRnVKqkgw ZSteam DistillationSteam Distillation ZExtractionExtraction

Why is this not Green?

What are some of the outcome of non Green Experiment? ZNeed to know how to set up simple distillation and extraction. (Techniques) ZIsolation yield. ZIdentify the identity of oil. ZIdentify the optical rotation of limonene.
