At NINGBO INNO PHARMCHEM CO.,LTD., we understand that the efficacy of our chemical products is rooted in their fundamental science. Ethyl Oleate, a compound we supply with high purity, is a fascinating example of an ester with a diverse application profile, driven by its unique chemical properties and synthesis methods.

Chemically, Ethyl Oleate is an ester formed through the condensation reaction between oleic acid and ethanol. Its molecular formula, C20H38O2, and molecular weight of approximately 310.51 g/mol, define its structure. Oleic acid itself is a monounsaturated omega-9 fatty acid, and its esterification with ethanol results in Ethyl Oleate, often referred to as ethyl (Z)-octadec-9-enoate. This structure, featuring a long hydrocarbon chain with a single cis double bond, contributes to its liquid state and its solubility characteristics.

The synthesis of Ethyl Oleate is typically achieved through direct esterification, often catalyzed by strong acids like sulfuric acid or p-toluenesulfonic acid. This process involves reacting oleic acid with an excess of ethanol under reflux conditions. Alternative methods, such as transesterification or enzymatic catalysis using lipases, are also employed, offering greener and more specific routes to produce high-purity Ethyl Oleate. The efficiency and purity achieved through these synthetic pathways are critical for its downstream applications, especially in the pharmaceutical sector.

Key physical properties of Ethyl Oleate include its appearance as a clear, colorless to pale yellow liquid. It is characterized by its low viscosity, high flash point (typically over 100°C), and insolubility in water, but solubility in most organic solvents. These properties make it an excellent solvent and carrier, particularly for lipophilic substances. Its relative stability and biodegradability further enhance its utility.

The understanding of these chemical properties of ethyl oleate is vital for formulators and researchers who rely on its predictable behavior. Whether it's used for its solvent capabilities, as a cosmetic emollient, or as a pharmaceutical excipient, the consistent quality derived from controlled synthesis is paramount.

NINGBO INNO PHARMCHEM CO.,LTD. ensures that the Ethyl Oleate we provide adheres to stringent quality controls, reflecting our commitment to delivering reliable chemical intermediates. Our expertise in chemical synthesis supports industries that depend on the precise application of compounds like Ethyl Oleate, driving progress and innovation.
