In the vast landscape of industrial chemicals, understanding the fundamental properties and applications of key compounds is paramount for informed procurement and utilization. Triethyl Phosphate (TEP), a significant organophosphorus ester, is one such chemical that warrants detailed examination. With its widespread use across various sectors, TEP has established itself as a valuable commodity. As a dedicated Triethyl Phosphate manufacturer and supplier based in China, we aim to provide a clear overview of this versatile compound, from its inherent characteristics to its diverse industrial roles.

Triethyl Phosphate, identified by CAS number 78-40-0, is a colorless, transparent liquid characterized by a mild, pleasant odor. Its chemical formula is C6H15O4P, and it possesses a molecular weight of 182.15 g/mol. Key physical properties include a boiling point of approximately 215°C, a melting point of around -56°C, and a density of 1.072 g/cm³. TEP is miscible with water and highly soluble in a wide range of organic solvents such as ethanol, ether, and benzene. This excellent solubility profile makes it a preferred choice for various formulation and reaction processes.

The production of Triethyl Phosphate typically involves an esterification reaction between phosphorus oxychloride (POCl3) or phosphorus trichloride (PCl3) and ethanol. Several synthesis routes exist, often involving two-step processes that carefully control reaction conditions, temperature, and purification steps to achieve high purity. The commitment to stringent quality control during manufacturing ensures that the TEP supplied by us meets the required specifications, with an assay typically exceeding 99.5% and low acid and water content.

The industrial applications of Triethyl Phosphate are remarkably diverse. Primarily, it is utilized as a high-boiling solvent in various chemical processes, owing to its excellent solvency power and thermal stability. TEP also functions as a plasticizer, imparting flexibility and enhancing the workability of polymers like cellulose derivatives and PVC. Furthermore, its flame-retardant properties make it a valuable additive for plastics, textiles, and coatings, contributing to improved fire safety. TEP also plays a role as a catalyst in specific organic reactions and as an intermediate in the synthesis of pesticides and other organophosphorus compounds.
