Overview
Dioleic acid, also known as 9,10-dioleic acid, is an unsaturated fatty acid derived from oleic acid. It is widely used in industrial applications due to its excellent lubricating and emulsifying properties. The compound is typically synthesized through the oxidation of oleic acid or derived from natural sources like vegetable oils. In B2B markets, dioleic acid is valued for its versatility and cost-effectiveness. It serves as a key ingredient in the production of lubricants, surfactants, and plasticizers. Its chemical stability and compatibility with other organic compounds make it a preferred choice for various formulations.
Physical and Chemical Properties
Dioleic acid is a pale yellow to colorless oily liquid with a characteristic mild odor. It has a molecular weight of 282.47 g/mol and a density of approximately 0.89 g/cm³ at 20°C. The compound melts at 13-14°C and decomposes at around 360°C. Its solubility profile makes it insoluble in water but highly soluble in organic solvents such as ethanol, ether, and chloroform. Dioleic acid exhibits high viscosity and excellent lubricity, which are critical for its industrial applications. Its chemical structure includes double bonds, making it susceptible to oxidation, which necessitates proper storage conditions.
Main Applications
Dioleic acid is primarily used in the formulation of industrial lubricants, where its high viscosity and lubricity reduce friction and wear in machinery. It is also a key component in surfactants and emulsifiers, aiding in the stabilization of mixtures in cosmetics, pharmaceuticals, and food processing. Additionally, the compound is employed as a plasticizer in the production of flexible plastics and resins. Its ability to improve the flexibility and durability of materials makes it valuable in the polymer industry. Other niche applications include its use in textile processing and as a corrosion inhibitor.
Safety and Storage
Dioleic acid is generally considered safe when handled properly, but it can cause skin and eye irritation upon direct contact. Proper personal protective equipment (PPE), such as gloves and goggles, should be worn during handling. Adequate ventilation is recommended to avoid inhalation of vapors. The compound should be stored in a cool, dry place away from light and oxidizing agents to prevent degradation. Containers must be tightly sealed to minimize exposure to air and moisture. In case of spills, absorbent materials like sand or vermiculite should be used for cleanup, followed by proper disposal.
B2B Procurement Guide
When procuring dioleic acid, B2B buyers should prioritize suppliers with certifications such as ISO or GMP to ensure product quality. Key factors to consider include purity levels (typically 90-99%), packaging options (drums, totes, or bulk), and delivery terms. Price negotiations should account for order volume, with discounts often available for large quantities. Buyers should also verify the supplier's ability to provide technical support and safety data sheets (SDS). Sampling before large-scale purchase is advisable to confirm product suitability for specific applications.
