Product Application of DL-Limonene CAS#138-86-3
Dipentene is used in making enamels, coatings, oil-based resins, resin waxes, metal driers, and solvents. It's also a starting material for synthetic resins and synthetic rubbers.
In the fragrance world, it's used in orange blossom and citrus scents, and it can even stand in for lemon essential oil. Chemically speaking, limonene can be selectively oxidized to make carvone; when you treat it with inorganic acids and water, you get α-terpineol and terpin hydrate. You can also hydrogenate it to get para-menthane or dehydrogenate it to get p-cymene, using platinum or certain catalysts.
Other uses include oil dispersants, rubber additives, wetting agents, and more.
