Butyl oleate

Butyl oleate (chemical formula C₂₂H₄₂O₂) is an important oleate ester compound with broad applications across multiple industrial sectors. Its primary uses are as follows:

I. Core Industrial Applications

1. ‌Plasticizer‌
   • Used as a plasticizer for materials such as polyvinyl chloride (PVC), chloroprene rubber, and ethyl cellulose to improve flexibility and processability. Particularly suitable for cold-resistant rubber products (e.g., rubber dams), maintaining elasticity at temperatures as low as -50°C.
2. ‌Lubricant and Waterproofing Agent‌
   • Serves as an additive for mechanical lubricants, a lubricant for drilling mud, and a waterproofing treatment agent for fabrics/materials.
3. ‌Solvent‌
   • Replaces toxic benzene-based solvents in industrial applications such as dye dispersants, coatings, and inks.

II. Specialized Functional Applications

1. ‌Diesel Anti-Wear Agent‌
   • Combined with mineral oil to form an environmentally friendly low-sulfur diesel anti-wear agent, reducing equipment wear and emission pollution.
2. ‌Surfactant‌
   • Used as a dye dust suppressant, textile antistatic agent, and leather fatliquoring agent (enhancing smoothness and texture).
3. ‌Industrial Additives‌
   • Functions as a polymer cross-linking agent, epoxy resin curing agent, metal flotation agent, and release agent.

III. Other Fields

• ‌Pesticide Excipient‌: Enhances the permeability of insecticides.
• ‌Gas Chromatography Stationary Phase‌: Used for analytical separation (operating temperature ≤120°C).

Key Physicochemical Properties

‌Pharmaceutical Application Note‌: Some studies mention its potential as a drug carrier, but current industrial applications are primarily in the chemical sector. Pharmaceutical use requires compliance with specific purification standards (e.g., low acid value, heavy metal control).
