3. Chemical Reactivity
As a fatty acid ester, Ethyl Oleate exhibits the common reactivity of such compounds. It can undergo hydrolysis. In the presence of an acid catalyst, it forms an equilibrium mixture of oleic acid, ethanol, and water. Under alkaline conditions, it undergoes saponification to produce oleate salts. Additionally, it can participate in aminolysis, alcoholysis, and transesterification reactions. For example, it reacts with ammonia to form oleic acid amide and ethanol, with other fatty alcohols to yield new oleate esters and ethanol, and with another ester to generate new oleate esters and carboxylic acid esters.
4. Applications
- Food Industry: It is approved as a flavoring agent in many regions. For instance, in China, GB 2760 - 1996 lists it as a permitted flavoring substance. It can be used as a flavor enhancer in a variety of food products, including baked goods, frozen dairy products, and beverages. It provides a certain flavor profile and can also contribute to the overall sensory experience of the food.
-
- Lubricant: Its oily nature makes it suitable as a lubricant in some applications, reducing friction between moving parts.
-
- Antihydroagent: It can be used as an anti - water agent, helping to repel water and prevent moisture - related issues in certain materials.
-
- Resin Plasticizer and Toughner: It can act as a plasticizer and toughner for resins, improving the flexibility, toughness, and processing properties of resins.
-
- Surface Active Agent Intermediate: It serves as an intermediate in the synthesis of surface - active agents.
-
- Solvent and Carrier: It is used as a solvent for various organic reactions and as an oil - based carrier for other substances. Also, it can be used as a stationary phase in gas chromatography (with a maximum operating temperature of 120 °C).
- Pharmaceutical Industry: It can be used as a pharmaceutical excipient, functioning as a solvent or carrier for lipophilic drugs such as steroids. It has also been investigated for use in drug delivery systems, including self - micro - emulsifying drug delivery systems (SMEDDS), transdermal delivery systems, and subcutaneous or intramuscular injection vehicles. However, its use in injectable formulations requires careful consideration as it has not been fully approved by the U.S. Food and Drug Administration for all injectable uses.
- Fragrance Industry: With its floral, fruity, and fatty - oily odor notes, it is used in the formulation of both 日化香精 (daily - use fragrance) and 食用香精 (food flavor). It can enhance the overall fragrance profile and contribute to a more appealing sensory experience in products such as perfumes, colognes, and scented personal care products, as well as in food flavorings.
5. Packaging and Storage
- Packaging: Usually packed in plastic - lined iron drums or glass bottles for sealing. The packaging size can vary, with common drum sizes being 20 kg or 180 kg.
- Storage: It should be stored in a cool, well - ventilated area, away from ignition sources and heat. Since it is light - sensitive, it is advisable to store it in a place protected from direct sunlight. It can be transported as a non - hazardous material, but proper handling precautions should still be taken to prevent spills and ensure product quality during transportation.
