Dioctyl Maleate, commonly abbreviated as DOM, is a highly versatile and crucial chemical compound widely utilized across numerous industries. Identified by its Chemical Abstracts Service (CAS) number 2915-53-9, DOM has the molecular formula C20H36O4 and a molecular weight of approximately 340.5 g/mol. It is a diester of maleic acid, distinguished by its unique chemical structure that imparts a broad spectrum of beneficial properties and applications.

Chemical Profile and Physical Properties
DOM typically presents as a clear, virtually colorless to pale yellow liquid, characterized by a mild, distinctive ester-like odor. Its physical characteristics make it particularly suitable for diverse industrial processes. Dioctyl Maleate exhibits a very low water solubility of about 0.6 mg/L at 25°C, indicating its hydrophobic nature. Conversely, it is readily soluble in various organic solvents. Key physical properties include a boiling point estimated to be in the range of 396°C to 418°C and a melting point around -60°C, confirming its liquid state at room temperature. Its density is approximately 0.99 g/cm³, and its refractive index is around 1.44. Furthermore, DOM boasts a relatively high flash point, typically between 185°C and 195.5°C, contributing to its safe handling and storage. These properties, combined with its notable low volatility and excellent thermal stability, underscore its reliability in demanding applications.

Versatile Applications Across Industries
The utility of Dioctyl Maleate spans a wide array of industrial sectors, primarily due to its multifunctional capabilities as a plasticizer, co-monomer, and chemical intermediate.

One of DOM’s most significant roles is as a plasticizer. It is extensively used in various resins, most notably in polyvinyl chloride (PVC), to impart and enhance flexibility and elasticity. As industries increasingly seek safer and more environmentally friendly alternatives, DOM stands out as a viable phthalate-free option, replacing traditional plasticizers like DOP in many formulations without compromising performance.

Beyond its plasticizing role, Dioctyl Maleate serves as a crucial co-monomer in polymerization reactions. It readily copolymerizes with a range of monomers, including vinyl acetate, vinyl chloride, acrylates, and stearates. This reactivity makes it an invaluable building block for synthesizing polymers with tailored properties.

The derivatives and copolymers of DOM find applications in the production of a variety of essential products:

• Adhesives: It enhances the adhesion strength and flexibility of adhesive formulations.
• Emulsion Paints: DOM contributes to improved film formation, durability, and washability in water-based paints.
• Surfactants and Wetting Agents: As a key chemical intermediate, especially in the synthesis of sodium dioctyl sulfosuccinate, DOM is critical for producing effective wetting agents used in detergents and other cleaning products.
• Textile Coatings: It plays a vital role in manufacturing coatings that endow textiles with properties such as waterproofing and heat resistance, essential for high-performance apparel and fabrics.
• Personal Care Products: DOM functions as an emollient and skin-conditioning agent, finding its way into formulations like moisturizers, cleansers, make-up, shampoos, and conditioners.
• Other Industrial Uses: Its versatility extends to being utilized in petroleum additives, rubber formulations, paper treatment agents, and paint fixing agents, showcasing its broad applicability.
