"Turpentine CAS No. 68956-56-9 （Pine oil）is widely used in many fields such as essence, fragrance, chemical industry and pharmacy. It can be used as a raw material for synthetic rubber, fragrance, and also as a solvent."
-Deshangchemical
Dipentene is derived from the distillation of turpentine oil. Insoluble in water, miscible with ethanol. Used as a raw material for synthetic rubber, fragrance, and also as a solvent. It has a fresh pine resin scent and excellent solvent properties.
1. The use of turpentine in the field of essence and fragrance
Solvent and diluent:
This is one of its most fundamental and important uses. Pine oil essence is an excellent solvent for many essential oils, resins, perfumes, synthetic fragrances (especially those with low polarity or oil solubility).
It is used to dilute and concentrate essence, making it easy to handle and mix.
In the preparation of perfume, cologne, floral water, air freshener, aromatic oil and other products, it is often used as a solvent carrier.
Aroma components:
Pine oil essence itself has the characteristics of fresh, pine wood, resin, and slightly citrus aroma. It is often used directly as a component of essence formula, especially in essence that needs to create the following flavor types:
Pine/needle flavor: essence with forest flavor such as pine, fir, spruce, etc.
Citrus aroma type: As a supplement or background to citrus aroma, it increases freshness and naturalness (although the effect is not as strong as pure d-limonene).
Lavender, rosemary, thyme and other herbal fragrances: providing a fresh and clean base.
Industrial flavor: such as detergent, soap essence and disinfectant essence, which can provide fresh and odor free effects.
Intermediate and synthetic raw materials:
Pine oil extract (dl limonene) is an important starting material for the synthesis of other more valuable spice compounds. Various fragrances can be derived through chemical reactions such as oxidation, hydrogenation, hydration, and epoxidation
Terpineol: It has floral aromas such as lilac and lily of the valley, and is a very important spice. Under acidic conditions, pine oil extract can be hydrolyzed to produce hydrated terpenoid diols, which can then be dehydrated to obtain pine oil alcohol.
Carvone: It has the aroma of spearmint or wolfberry.
Intermediate for the synthesis of Menthol.
2. Other industrial uses of turpentine
Industrial solvents and cleaning agents:
Degreasing agent: effectively dissolves grease, lubricating grease, asphalt, tar, etc., commonly used for degreasing cleaning before metal processing and cleaning of mechanical parts.
Printing ink cleaner: cleans the printing press drum and screen.
Electronic industry cleaning agent: used to remove residues such as rosin flux (compatibility should be noted).
Adhesive remover: Remove adhesive residue from tape and labels.
Universal hard surface cleaner: added to floor cleaners, kitchen cleaners, and paint removers to enhance cleaning power and bring a fresh scent.
Coatings and paint industry:
Solvent: As a solvent or co solvent for oil-based coatings, varnishes, and porcelain paints, it regulates viscosity and drying speed.
Resin modifier: used for synthesizing or modifying some resins (such as phenolic resins, alkyd resins).
Leveling agent: improves the leveling performance of coatings.
Rubber and Plastic Industry:
Dispersant: Helps disperse pigments and fillers in rubber mixing.
Plasticizer/Softener: Used for certain rubbers and plastics.
Reuse agent: Used as a desulfurization activator in the regeneration process of waste rubber.
