One commonly performed natural product isolation is the extraction of R - (+)-limonene from the fruit of Citrus sinensis (i.e., the orange tree). separate the enantiomers using physical separation methods. If there is an odd number of students, then the student will do either 2. Experiment 6.2 Isolation of (R)-(+)-Limonene from Orange Peels and Chemical Tests Lotte Kranzo Tuesday L82 Rachel 11/2/21 Purpose: The purpose of this lab was to determine and analyze the polarimetry of the extraction of essential oil from an orange peel using a variety of different techniques like steam distillation and extraction. Along with this it can also be used as safer and alternative means of food preservation. You will note that, in addition to the unsaturation, limonene has a chiral carbon. To meet this goal steam distillation was implemented, as it lowered the organic molecule's high boiling point, from 176 to 90 , allowing the substance to be evaporated and condensed in a similar manner as water. Results & discussion. Rotation of Limonene: Bf = 195. 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 method used in this lab to extract limonene from the orange peel was steam distillation, which is used to separate temperature sensitive compounds such as aromatic compounds. The much smaller peaks are small traces of impurities present in the product. The heavy white pulp which constitutes the bulk of the orange peel is not to bee used.
