Limonene

Organic Chemistry Lab Friday, celestial latitude 14, 2012 Formal Lab-report: Steam distillation and polarimetry 08 Fall 08 Fall Abstract R-(+)Lim mavinne was extracted from the outer leach of an orange tree. victimization co-distillation (steam distillation) the 17.5-mL of distillate was extracted from the mixture and was broken in in a separatory funnel. The radical layer containing the extract was detached and dried apply anhydrous magnesium sulfate. The extract was acquit g spoke purified, by removing the dichloromethane on an explosion-proof-hot-plate. The purity of the limonene was sustain by polarimetry. Purity of the ingathering was 33.8% with an observed rotation of +3.25° at 26.7°C compared to the literature of clarified limonene, +125.6°.

A pine is a hitchhike from the genus Pinus, plot oranges are fruit, an wrap up spring of a citrus tree tree. some(prenominal) grow in different climates and have almost postal code in common. However, taking a closer come along shows that the 2 are very more similar therefore they whitethorn seem. The pine goad leaf and the outer orange peel contain a molecule called limonene. The limonene molecule has ii enantiomers, one with a arbitrary (+) and the other with a negatively charged (-) stereocenter.
