Limonene; commonly known as lemon olein, is a cyclic monoterpene widely found in various essential oils.
At room temperature, these two isomers are both colorless and flammable liquids with a strong pleasant fragrance.
L-limonene smells It has a lemon/turpentine flavor, while d-limonene has a lemon/orange flavor. ;
Especially in lemon oil, lemon wormwood oil, orange oil, bergamot oil, dill oil. Limonene molecule contains a chiral center, including L-limonene, dextro-limonene optical isomers, and a racemate.
Methods of production:
Exist widely in natural plant essential oils. Among them, tangerine oil, lemon oil, orange oil, camphor white oil, and so on mainly contain dextrorotation. There is peppermint oil and so on that contain L-body. The racemates are neroli oil, cedar oil, and camphor white oil. In the manufacture of this product, the above-mentioned essential oils are separately obtained by fractional distillation.
Terpenes can also be extracted from ordinary essential oils, or produced as by-products in the process of processing camphor oil and synthesizing camphor. The obtained dependence can be purified by distillation to obtain limonene.
Use turpentine as raw material, carry out fractional distillation, cut out α-pinene, make camphene through isomerization, and then obtain it by fractional distillation. The by-product of camphene is dipentene. In addition, dependence can be by-produced when turpentine is used to hydrate terpineol.
Calcium chloride or anhydrous sodium sulfate dehydration and then vacuum distillation.

Dipentene is used as enamel, lacquer, and various oil-containing resins, resin waxes, metal driers, and solvents; used to make synthetic resin synthetic rubber; used to blend neroli, citrus oil flavors, etc.; can also be made It is a substitute for lemon essential oil.
Industrial dipentene is a by-product obtained when turpentine is used as a raw material to synthesize camphor or terpineol. It is a liquid mixture composed of compounds such as monocyclic terpenes and bicyclic monoterpenes. The main components are limonene (dipentene) and pinol. Alkene, the molecular formula is C10H16.
Under the action of platinum or color catalyst, hydrogenation produces para-alkane, and dehydrogenation produces para-cymene. Also used as oil dispersant, rubber additive, wetting agent, etc.
The directional oxidation of limonene produces carvone; in the presence of inorganic acid, the addition reaction of limonene with water produces α-terpineol and hydrated terpene glycol;
Transportation vehicles should be equipped with corresponding types and quantities of fire-fighting equipment and leakage emergency treatment equipment.
Dipentene is best to transport sooner or later in summer.
The tank (tank) truck used during transportation should have a grounding chain, and a hole partition can be set in the tank to reduce vibration and static electricity.
Mixed shipment and transportation with oxidants, acids, edible chemicals, etc. are strictly prohibited.
Avoid exposure to the sun, rain, and high temperature during transportation.
Stay away from fire, heat sources, and high-temperature areas during stopovers.
The exhaust pipe of the vehicle carrying the item must be equipped with a fire arrester, and it is forbidden to use mechanical equipment and tools that are prone to sparks for loading and unloading.
When transporting by road, follow the prescribed route and do not stop in residential areas and densely populated areas.
DL-Limonene is forbidden to drop off during railway transportation. It is strictly forbidden to transport in bulk by wooden ships or cement ships.
