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,

空気と水の反応
Highly flammable. Insoluble in water.
反応プロフィール
(+)-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.
火災危険
(+)-Dipentene is combustible.

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

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.
