Limonene-3D-balls

Limonene is a colourless liquid hydrocarbon, classified as a cyclic terpene. The D-isomer is the most common form encountered. The name comes from the lemon, as many citrus fruits and some evergreen plants contain high amounts of the D-isomer. It may be recognized as the smell of oranges, lemons, or other citrus fruits.

PropertiesEdit

ChemicalEdit

Limonene is a relatively stable terpene and can be distilled without decomposition, although at elevated temperatures it cracks to form isoprene.

PhysicalEdit

Limonene is a colorless liquid hydrocarbon. It has a strong smell of orange or lemon peels.

AvailabilityEdit

Limonene can be extracted from citrus fruit peels.

Pure limonene can also be bought online.

PreparationEdit

The synthesis of limonene from basic hydrocarbons is complex, instead it's more efficient to extract it from citrus fruit juice.[1] It is often prepared in introductory organic chemistry classes by steam distilling an orange peel.

ProjectsEdit

  • Extract limonene from limes, lemons, or oranges

SafetyEdit

Limonene and its oxidation products are skin and respiratory irritants, and limonene-1,2-oxide (formed by aerial oxidation) is a known skin sensitizer.
