Trioctyl Trimellitate (TOTM), also known as Tris(2-ethylhexyl) Trimellitate or PX-338, is a highly regarded chemical compound with the CAS number 3319-31-1. It is a critical component in various industrial applications, primarily serving as a high molecular weight plasticizer and a synthetic lubricant ester. NINGBO INNO PHARMCHEM CO.,LTD. is proud to be a leading producer of this versatile compound, ensuring its availability for demanding industrial needs.

Chemically, TOTM has a molecular formula of C33H54O6 and a molecular weight of 546.78. It typically presents as a colorless to slightly yellow oily liquid with a mild odor. Key physical properties contributing to its widespread utility include a boiling point of 414°C, a density of 0.990 g/mL at 20°C, and a high flash point of 505°F. These characteristics underscore its remarkable thermal stability and low volatility, which are crucial for its high-performance applications. While it exhibits excellent solubility in common organic solvents like chloroform, TOTM is notably insoluble in water.

One of TOTM's primary applications is as a superior plasticizer, particularly for polyvinyl chloride (PVC) formulations. Its branched structure and high molecular weight confer exceptional properties to PVC products, including excellent low volatility, good heat resistance, and superior electrical properties. These attributes make TOTM an ideal choice for critical applications where durability and long-term performance are paramount. It is widely utilized in the manufacturing of vinyl automotive interior components, where low fogging and extended lifespan are essential. Furthermore, TOTM is extensively used in electrical insulation for wires and cables, as well as in molded parts like dishwasher gaskets and seals, ensuring product integrity and safety over time. As a non-phthalate plasticizer, TOTM serves as an environmentally preferred alternative, aligning with growing industry demands for safer and more sustainable materials.

Beyond its role in plastics, TOTM is also highly valued as a high-performance synthetic lubricant ester. Its robust chemical structure and excellent thermal and oxidative stability make it an ideal base fluid or additive for lubricants designed for extreme conditions. TOTM's ability to maintain high viscosity and lubricating properties under elevated temperatures makes it indispensable in formulations for engine oils, compressor oils, and high-temperature chain oils. It is also a key component in various greases, contributing to their efficacy and longevity in demanding industrial machinery. The production of TOTM involves the acid-catalyzed esterification of trimellitic anhydride with 2-ethylhexanol, a process meticulously controlled by NINGBO INNO PHARMCHEM CO.,LTD. to ensure product purity and consistent quality.
