DIPENTENE Chemical Properties,Usage,Production

Description

dl-Limonene has a pleasant, lemon-like odor free from campho raceous and turpentine-like notes. The most important and wide spread terpene; it is known in the d- and ι- optically active forms and in the optically inactive dl-iovm (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); the most widespread form is the d-limonene, followed by the racemic form, and then ι-limonene.

Definition

ChEBI: Limonene is a monoterpene that is cyclohex-1-ene substituted by a methyl group at position 1 and a prop-1-en-2-yl group at position 4 respectively. It has a role as a human metabolite. It is a cycloalkene and a p-menthadiene.
