Synthesis of Lubricants and Plasticizers (Main Uses)
Refrigeration lubricating oil: A highly efficient lubricant synthesized through esterification reaction, with excellent low-temperature resistance (does not solidify at -40℃), and is used in air conditioning compressors.
Plasticizer: Reacts with alcohols to form esters, enhancing the flexibility and weather resistance of materials such as PVC.
Coatings and drying accelerators
Alkyd resin modification: Enhances the yellowing resistance and impact strength of the paint film, replacing traditional phthalic anhydride.
Metal soap raw materials: Produce cobalt and manganese salt drying accelerators to accelerate the curing of coatings.
Medicine and Cosmetics
Pharmaceutical intermediates: Synthetic antibiotics and anti-cancer drugs (with a purity grade of ≥99%).
Cosmetic esters: Isononyl isononate is used to improve the texture of skin care products, providing a refreshing and non-greasy skin feel.
Emerging fields
Environmentally friendly materials: Biodegradable lubricant raw materials, reducing industrial pollution.
Agricultural chemicals: Synthetic plant growth regulators to enhance the stress resistance of crops.
Health risk:
Corrosiveness: Strongly irritating to skin, eyes and respiratory equipment (R36/37/38). A gas mask and acid and alkali resistant gloves are required for operation.
Inhalation toxicity: Respiratory tract inflammation caused by high concentration vapor (Safety term: S22-S24/25).
Storage and transportation
Keep sealed and away from light. Store in a cool place at ≤25℃ with a relative humidity of less than 75%.
Transport identification: UN 3265 (Corrosive Liquid).
Environmental protection compliance
Export to the European Union requires REACH certification, and for pharmaceutical/cosmetic grades, it complies with FDA standards.
