Understanding the technical specifications and properties of industrial chemicals is vital for making informed purchasing decisions. Bis(2-ethylhexyl) maleate (CAS 142-16-5), also known as Dioctyl Maleate (DOM), is a chemical compound with a well-defined set of characteristics that dictate its performance in various applications. As a leading manufacturer and supplier of Bis(2-ethylhexyl) maleate from China, we are pleased to share detailed insights into its properties, specifications, and the manufacturing processes that ensure its quality.

Bis(2-ethylhexyl) maleate is an organic compound with the molecular formula C20H36O4 and a molecular weight of approximately 340.5 g/mol. It is a diester formed from maleic acid and 2-ethylhexanol. Physically, it presents as a clear, colorless to almost colorless liquid, a characteristic that is crucial for applications where visual clarity is important, such as in coatings and clear plastic formulations. Its low melting point (around -50°C) ensures it remains liquid even at cooler temperatures, facilitating easier handling and processing compared to solid additives.

Key specifications that define the quality of Bis(2-ethylhexyl) maleate include its purity, typically measured by Gas Chromatography (GC). High-purity grades, often exceeding 93.0% (GC), are commonly required for demanding applications like pharmaceutical intermediates and high-performance polymers. Other important parameters include its density, refractive index, and boiling point. For instance, its density is approximately 0.944 g/mL at 25°C, and its refractive index (n20/D) is around 1.455. These values are critical for quality control and for ensuring consistent performance in formulated products. We meticulously control these parameters during our manufacturing process.

The manufacturing of Bis(2-ethylhexyl) maleate typically involves the esterification reaction between maleic anhydride or maleic acid and 2-ethylhexanol. This process requires careful control of temperature, pressure, and catalyst to achieve high yields and purity. As a manufacturer, our state-of-the-art facilities are equipped with advanced reactors and purification systems, enabling us to produce Bis(2-ethylhexyl) maleate that meets rigorous international standards. We are committed to sustainable manufacturing practices and efficient production to offer our clients competitive pricing.
