⚗️ Chemical & Physical Properties
Ethyl octanoate is a colorless liquid with a fruity odor, reminiscent of oranges or pineapples, making it a common ingredient in flavorings and fragrances. The distinctive aroma of ethyl octanoate is often described as sweet and pleasant, contributing to its wide use in the food and cosmetic industry.
With a molar mass of 158.26 g/mol and a density of 0.870 g/cm³, ethyl octanoate falls within the range of common food items in terms of both molar mass and density. For example, sugar has a molar mass of 342.30 g/mol and a density of 1.59 g/cm³, which are noticeably higher than those of ethyl octanoate.
Ethyl octanoate has a melting point of -78.5°C and a boiling point of 216°C, which are relatively low compared to common food items. For instance, salt has a melting point of 801°C and a boiling point of 1,465°C, highlighting the lower melting and boiling points of ethyl octanoate in comparison.
This compound is sparingly soluble in water and exhibits low viscosity, characteristics that set it apart from common food items. For example, salt is highly soluble in water and has a high viscosity, emphasizing the differences between ethyl octanoate and typical food ingredients in terms of solubility and viscosity.
🏭 Production & Procurement
Ethyl octanoate, commonly known as ethyl caprylate, is typically produced through the esterification of octanoic acid and ethanol. This process involves the reaction of the carboxylic acid group in octanoic acid with the hydroxyl group in ethanol, resulting in the formation of Ethyl octanoate and water. Catalytic agents, such as sulfuric acid, are often utilized to facilitate this reaction.
Ethyl octanoate can be procured from chemical manufacturers or suppliers specializing in flavor and fragrance ingredients. It is commonly available in bulk quantities for industrial use, as well as in smaller quantities for research purposes. Due to its volatile nature and fruity aroma, Ethyl octanoate is sensitive to heat and light, requiring careful storage and transportation to prevent degradation.
Transportation of Ethyl octanoate is typically done in sealed containers, such as drums or tanks, to minimize exposure to air and moisture. Proper labeling and documentation in accordance with regulations on hazardous materials are essential for safe and compliant transportation. Specialized carriers familiar with handling chemical substances are often employed to ensure the secure and efficient delivery of Ethyl octanoate to its intended destination.
