Beschreibung
d-Limonene has a pleasant, lemon-like odors free from campho raceous and turpentine-like. d-Limonene may be obtained by
steam distillation of citrus peels and pulp resulting from the pro duction of juice and cold-pressed oils, or from deterpenation of
citrus oils; it is sometimes redistilled.
The most important and widespread terpene; it is known in the el and I- optically active forms and in the optically inactive dl-form
(known as dipentene); it has been reported found in more than 300
essential oils in amounts ranging from 90 - 95% (lemon, orange,
mandarin) to as low as 1% (palmarosa);1 the most widespread form
is the d-limonene, followed by the racemic form, and then ι-
limonene.
Chemische Eigenschaften
colourless liquid
Occurrence
It has been reported found in more than 300 essential oils in amounts ranging from 90 to 95% (lemon, orange,
mandarin) to as low as 1% (palmarosa); the most widespread form is the d-limonene, followed by the racemic form and then l-limo nene. Also reported found in ginger, nutmeg, pepper, mace, hop oil, coriander seed, calamus, dill herb, caraway seed and rosemary.
Verwenden
Chiral building block. Biodegradable solvent. Limonene is used as a solvent for filament-fused 3D printing, in cosmetic products, as a fragrance and as a biofuel. It is useful to promote weight loss, prevent cancer, treat cancer and treat bronchitis. It also finds use in foods, beverages, chewing gum, as a flavoring agent and a shrinking agent to dissolve polystyrene. It acts as a chiral intermediate for natural product synthesis.
synthetische
d-Limonene may be obtained by steam distillation of citrus peels and pulp resulting from the production of juice and cold pressed oils, or from deterpenation of citrus oils; it is sometimes redistilled.
Definition
ChEBI: An optically active form of limonene having (4R)-configuration.
Allgemeine Beschreibung
Clear colorless mobile liquid with a pleasant lemon-like odor.
Air & Water Reaktionen
Highly flammable. Insoluble in water.
Reaktivität anzeigen
(+)-Dipentene is sensitive to exposure to light. Atmospheric oxidation can occur. (+)-Dipentene is incompatible with strong oxidizing agents. (+)-Dipentene reacts violently with (iodine pentafluoride + tetrafluoroethylene). With dry hydrogen chloride or hydrogen bromide, (+)-Dipentene forms monohalides. With aqueous hydrogen chloride or hydrogen bromide, (+)-Dipentene forms the dihalide.
Brandgefahr
(+)-Dipentene is combustible.
Landwirtschaftliche Anwendung
Insecticide, Animal and insect repellant, Slimicide: Used as an insecticide, insect repellent, and animal
repellent. Not listed for use in EU countries. Registered
for use in the U.S., Canada and other countries. There are
49 global suppliers.

Kontakt-Allergie
d-Limonene is contained in Citrus species such as citrus,
orange, mandarin, and bergamot. d-limonene, used
as a solvent, may be found in cleansing or in degreasing
agents. Its sensitizing potential increases with prolonged
air contact, which induces oxidation and leads
to oxidation products. The presence of d-limonene has
to be mentioned by name in cosmetics of the EU.
