2EHA High-Purity Acrylate Monomer | 50,000 Tons Annual Capacity

The 2-ethylhexyl acrylate (2EHA) production process involves a series of chemical reactions and purification steps to synthesize the high-purity monomer, leveraging advanced technologies to ensure quality and efficiency. The process begins with the esterification of acrylic acid (CH2=CHCOOH) with 2-ethylhexanol (C8H18O), a reaction catalyzed by acids (such as sulfuric acid or solid acid catalysts) under controlled temperature and pressure conditions. This reaction forms 2EHA and water as a byproduct, which is removed to drive the reaction toward completion. After esterification, the crude product undergoes purification to achieve the 99% purity required for high-performance applications. Purification typically involves distillation—using fractional distillation columns to separate 2EHA from unreacted starting materials, byproducts, and impurities based on differences in boiling points. E Plus Chemical Co., Ltd. enhances this process with advanced catalytic polymerization technology, optimizing catalyst selection and reaction parameters to increase yield and reduce impurities. The company’s fully automated production lines ensure precise control over temperature, pressure, and reaction time, minimizing variability between batches. Post-distillation, inhibitors (such as hydroquinone derivatives) are added to prevent premature polymerization during storage and transportation. Throughout the process, quality control checks monitor purity, acidity, and other key parameters, ensuring compliance with specifications. E Plus Chemical’s integrated industrial chain—controlling every step from raw material sourcing to final packaging—streamlines the production process, enhancing efficiency and ensuring the consistent quality of its 2EHA, which is used in adhesives, resins, and coatings.
