Pre-Lab (Isolation of Limonene from Citrus Fruits) Intro and background The limonene is defined as a colorless liquid hydrocarbon with a lemon like scent, present in lemon oil, orange oil, and similar essential oil. The limonene is really used in the fragrance and flavor chemistry sector. Also, the limonene has two kinds; R-(+)- enantiomer and S-(-)- enantiomer. The R-(+)- enantiomer of limonene is commonly isolated from the zest peelings of orange, while S-(-)- enantiomer is found in lemons. In this lab, we will purify the limonene collect by steam distillation and liquid CO 2 extraction. After doing this experiment, we will understand limonene from citrus fruits and steam distillation and CO 2 extraction techniques. Physical constant 1. R(+)-Limonene a. Molecular formula: C 10 H 16 b. Appearance: Colorless liquid c. B.P: 175.5 d. M.W=136.24g/mol 2. (-)-( S )-limonene a. Molecular formula: C 10 H 16
