Description of Cajeputen

Limonene is a colorless liquid hydrocarbon classified as a cyclic terpene. The more common d-isomer possesses a strong smell of oranges. It is used in chemical synthesis as a precursor to carvone and as a renewables-based solvent in cleaning products.
Limonene takes its name from the lemon, as the rind of the lemon, like other citrus fruits, contains considerable amounts of this compound, which contributes to their odor. Limonene is a chiral molecule, and biological sources produce one enantiomer: the principal industrial source, citrus fruit, contains d-limonene ((+)-limonene), which is the (R)-enantiomer. Racemic limonene is known as dipentene. d-Limonene is obtained commercially from citrus fruits through two primary methods: centrifugal separation or steam distillation.

What’s the application of DL-Limonene?

• Commonly used as its dextrose. Can be used as a raw material for the formulation of artificial orange blossom, sweet flower, lemon, bergamot oil. It can also be used as a fresh head fragrance for make-up, soap, and daily chemical fragrances, and is suitable in cologne type, jasmine type in floral fragrances, lavender type, and pine, aldehyde, wood, fruit, or clear fragrances. Food flavor as a modifier for white lemon, fruity and spicy formulations, used as raw materials for synthetic rubber, spices, also used as a solvent; used as magnetic paint, fake paint and a variety of oleaginous resins, resin wax, metal catalysts, and solvents; used in the manufacture of synthetic resins synthetic rubber; used to blend orange blossom flavor, citrus oil flavor, etc.; can also be made into a substitute for the essential oil of the lemon system. In the presence of inorganic acid, limonene reacts with water to produce α-pinene alcohol and hydrated terpene glycol; hydrogenation under the action of platinum or color catalyst produces p-alkane, and dehydrogenation produces p-cymene. It is also used as an oil dispersant, rubber additive, wetting agent, etc. Used as a solvent, also used in fragrance synthesis and pesticide production.
