Lara A. El Said CHEM 237 Texas A&M - Qatar (R)-(+)-Limonene ABSTRACT: Limonene was extracted from orange peels by performing steam distillation and extraction. The major constituent of the steam-volatile oil of grapefruit or orange peel is (R)-(+)-limonene. 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. -toxic The index is a ratio of the velocity of light in the air to the velocity of the Set up the distillation apparatus with an empty fractional distillation column, and a 50 mL graduated cylinder containing 10 mL of saturated aqueous NaCl. A) True B) False, Why are bags placed around the many clusters of ripening date fruits each summer? contact with The CO 2 is used as a greener alternative to tradition techniques, such as using Assuming that our sample is entirely. Extracting limonene from oranges. Limonene evaporates easily at room temperature and keep the container covered all the time. If you leave the tube in the water long enough, eventually the liquid all evaporates and the pressure decreases.
