Specific Rotation 10 Set up the distillation apparatus as shown above. Purpose : The purpose of this experiment was to extract R-Limonene from a sample of orange or grapefruit using steam distillation and use the extract to determine the optical rotation of our sample; the optical rotation will then allow us to calculate the enantiomeric excess of R-Limonene in our distillate, as compared to a racemic mixture of R-Limonene and L-Limonene. It is also safer as it nonflammable, nontoxic, ea. In this lab, extractions, classification tests, and a distillation was performed in order to isolate two natural products, eugenol and limonene. Add grated orange peel. Orange while utilizing liquid CO2 while utilizing liquid CO2 expected percentage yield should be.! limonene, we can calculate the enantiomeric excess as follows: Two other ways we can isolate R-limonene are using a soxhlet extractor (2) and a cold press, The soxhlet extraction is similar to distillation, but it feeds the condensed vapors into a thimble, of packed filtering substances (like a filter paper). Learn from other educators. Once it passes through the filtering thimble The viscosity of SC-CO2 increases rapidly in the critical region, its order of magnitude is an order less than those of liquid organic solvents even at very high pressures.
