Ethyl oleate
SINOBIO
2916150000
Ethyl oleate (CAS 111-62-6) is an ethyl fatty acid ester produced by the esterification reaction of oleic acid and ethanol. Its core information is as follows:
* Chemical Formula: C₂₀H₃₈O₂
* Molecular Weight: 310.51 g/mol
* Structural Characteristics: Based on oleic acid (cis-9-octadecenoic acid), the carboxyl group condenses with the hydroxyl group of ethanol to form an ester bond, containing one carbon-carbon double bond (C=C).
* Appearance: Colorless to pale yellow transparent oily liquid with a floral aroma.
* Density: 0.87 g/cm³ (25℃).
* Melting Point: -32℃.
* Boiling Point: 216-218℃ (15 mmHg).
* Solubility: Insoluble in water, readily soluble in organic solvents such as ethanol, ether, and chloroform.
*Chemically stable, but contact with strong oxidizers, strong acids, and strong alkalis should be avoided.
*Storage conditions: Store in a sealed container in a cool, dark place, away from fire.
Ethyl oleate is a fatty acid ester, with the general chemical properties of esters, such as easy to hydrolyze in the presence of acid, alkali and other catalysts, ester exchange and other reactions.
Mainly through the esterification reaction of oleic acid and ethanol. Mix oleic acid and ethanol, add catalyst (such as concentrated sulfuric acid or p-toluenesulfonic acid), heating reflux, cooling and neutralization with alkali to pH 8 ~ 9, washed with water to neutral, and then dried by anhydrous calcium chloride for distillation under reduced pressure, the interception of ethyl oleate fraction can be obtained. In addition, it can be prepared by other catalysts (such as mesoporous molecular sieve SBA-15-SO3) or ester exchange reaction.

*Pharmaceutical Solvent: As a solubilizer for lipid-soluble drugs, especially in oil solutions for injection, it can improve drug solubility and reduce injection site irritation.
*Cosmetic Ingredient: Due to its good moisturizing properties and skin compatibility, it is widely used in lotions, creams, conditioners, and other products, acting as a softening and moisturizing agent for the skin.
*Edible Flavoring: Listed as a permitted natural equivalent flavoring in GB 2760-1996, it is used in beverages, confectionery, baked goods, etc., with maximum permissible usage varying depending on the food category (e.g., 40 mg/kg for confectionery, 55 mg/kg for baked goods).
*Food Additive: As a lubricant, water-repellent agent, and resin toughening agent, it improves food processing performance.
*Lubricants and Solvents: Used as lubricants and release agents under high temperature and high pressure conditions in precision machinery, rubber processing, and plastic molding.
*Gas Chromatography Stationary Solution: Maximum operating temperature 120℃, solvent is methanol or ether.
*Biodiesel additives: As an environmentally friendly solvent, they enhance the lubricity of biodiesel.
Ethyl oleate, also known as 9-octadecenoic acid ethyl ester, is a colorless oily liquid with a significant aroma. It is insoluble in water but soluble in most organic solvents. Ethyl oleate belongs to the category of ester derivatives and has various functions and applications.
1. Food additive: Ethyl oleate is commonly used as a food flavoring additive. It finds widespread application in the production of food and beverages, enhancing their aroma and taste.
2. Organic synthesis and fine chemicals: It is also employed as a common organic synthesis intermediate and a raw material for fine chemical production.
3. Lubricant and plasticizer: Ethyl oleate is used as a lubricant and plasticizer, improving the flow and processability of materials.
4. Pharmaceutical applications: It is used as a solvent in drug formulations containing lipophilic substances such as steroids.
5. Surface active agent: Ethyl oleate can also be used as a surfactant, which helps to reduce the surface tension of liquids and improve wetting, spreading, and emulsifying properties.
6. Resin toughening agent and antiwatering agent: It is also employed in the production of resin toughening agents and antiwatering agents.
In addition, when storing ethyl oleate, it should be kept in a cool and ventilated warehouse, away from fire and heat sources. It should also be protected from contact with air, light, and oxidizing agents. Avoid eye and skin contact to prevent irritation.
It's worth noting that the specific application and function of ethyl oleate may vary depending on the industry and the specific requirements of the product. It's important to follow the guidelines and regulations set by the relevant authorities to ensure safe and effective use.
