Isooctyl Ester

Updated: 2026-07-15

Overview

Isooctyl ester, also known as 2-ethylhexyl ester, is a chemical compound widely used in industrial applications due to its excellent plasticizing and lubricating properties. It is a colorless to pale yellow liquid with a mild odor and is primarily utilized in the production of PVC plastics, coatings, and adhesives. Its molecular structure, characterized by a branched carbon chain, contributes to its high stability and low volatility. These properties make it a preferred choice for applications requiring durable and long-lasting performance.

Physical and Chemical Properties

Isooctyl ester exhibits a density of approximately 0.89 g/cm³ and a boiling point ranging between 200-220°C. It is soluble in most organic solvents but insoluble in water, making it suitable for hydrophobic applications. The compound's low volatility and high thermal stability ensure minimal evaporation and degradation under high-temperature conditions. These characteristics are particularly beneficial in plasticizers, where long-term performance is critical.
