💡 Commercial Applications
Limonene, (+)- is a natural compound derived from citrus fruits with a variety of commercial and industrial applications. It is commonly used as a solvent in cleaning products, due to its ability to dissolve oils and grease effectively. Limonene is also utilized as a flavoring agent in food products such as beverages, baked goods, and chewing gum.
Additionally, Limonene is found in a wide range of industrial products including fragrances, cosmetics, and personal care items. Its pleasant citrus scent makes it a popular choice for perfumes, lotions, and air fresheners. In the manufacturing sector, Limonene is used as a component in the production of plastics, resins, and adhesives due to its ability to act as a solvent and improve adhesion properties.
In the realm of pharmaceuticals, Limonene has shown promising potential for medicinal purposes. Research suggests that Limonene may have anti-inflammatory, antioxidant, and antimicrobial properties, making it a valuable candidate for use in drugs and medications. It is currently being studied for its potential effects in cancer treatment, as well as its ability to alleviate symptoms of digestive disorders such as gastric reflux and indigestion.
⚗️ Chemical & Physical Properties
Limonene, (+)-, is a colorless liquid with a strong citrus odor. It is commonly found in the rind of citrus fruits, such as lemons and oranges, and is often used as a flavoring agent in foods and beverages.
With a molar mass of 136.23 g/mol and a density of 0.841 g/cm^3 at 20°C, limonene is relatively light compared to common food items like sugar (molar mass of 342.3 g/mol) and vegetable oil (density of around 0.92 g/cm^3).
Limonene has a melting point of -74°C and a boiling point of 176°C. This is significantly lower than the melting point of butter (around 32°C) and the boiling point of water (100°C), making it easy to work with in food preparations.
Limonene is insoluble in water but soluble in organic solvents. It has a relatively low viscosity, making it easy to mix into food products. In comparison, salt and sugar are highly soluble in water, and honey has a higher viscosity than limonene.
🏭 Production & Procurement
Limonene, (+)- is predominantly produced through the steam distillation of citrus peels, particularly those of oranges. The process involves heating the peels in water and then collecting the evaporated limonene oil.
Limonene, (+)- can be procured from various suppliers who specialize in the extraction and production of essential oils. It is typically sold in liquid form in sealed containers to prevent oxidation and contamination. Transportation of limonene, (+)- is done using specialized containers that ensure the stability and safety of the product during transit.
Once procured, limonene, (+)- can be transported via road, rail, sea, or air to reach its destination. Proper handling and storage conditions are crucial to maintain the quality and shelf-life of the product. It is important to comply with regulations regarding the transport of hazardous substances when dealing with limonene, (+)-.
⚠️ Safety Considerations
