CAS 10311-7: 2-Ethylhexyl Acrylate Properties & Industrial Uses

2-Ethylhexyl acrylate (2EHA) with CAS 103117 exhibits a unique combination of physical and chemical properties that make it a versatile monomer in adhesives, coatings, and resins. Physically, it is a clear, colorless to pale yellow liquid with a mild, characteristic odor, a density of approximately 0.885-0.895 g/cm³ at 25°C, and a refractive index of 1.435-1.440, which aids in quality control and identification. It has a low viscosity (1-5 mPa·s at 25°C), enabling easy mixing and processing in industrial formulations. As a flammable liquid, it has a flash point of 60-70°C (closed cup) and a boiling point of around 215-218°C, requiring specific handling and storage precautions to prevent ignition. Chemically, 2EHA is defined by its molecular formula C11H20O2, with a structure consisting of a reactive acrylate group (CH2=CH-COO-) and a branched 2-ethylhexyl chain. This structure allows it to undergo free radical polymerization, copolymerizing with various monomers to form polymers with tailored properties. The acrylate group’s double bond (C=C) is highly reactive, facilitating efficient polymerization, while the branched alkyl chain imparts flexibility, low glass transition temperature (Tg), and hydrophobicity to the resulting polymers. 2EHA is relatively stable under normal conditions but may polymerize spontaneously in the presence of heat, light, or initiators, which is why inhibitors (e.g., hydroquinone monomethyl ether) are added during production to prevent premature polymerization during storage and transportation. It is insoluble in water but soluble in organic solvents like ethanol, acetone, and toluene, making it compatible with both solvent-based and water-based emulsion formulations. E Plus Chemical Co., Ltd. ensures that its 2EHA with CAS 103117 maintains these properties consistently, with a purity of 99% achieved through advanced catalytic polymerization and purification processes, ensuring minimal impurities that could alter its chemical behavior or physical characteristics. These properties collectively make 2EHA with CAS 103117 a critical ingredient in high-performance polymer formulations, contributing to the functionality and durability of end products across industries.
