Tris(2-butoxyethyl) Phosphate, widely known by its acronym TBEP and identified by CAS number 78-51-3, is a crucial organophosphate ester with a broad spectrum of industrial applications. Its unique chemical structure and favorable physical properties make it an indispensable additive in sectors ranging from polymers and coatings to textiles and adhesives. For chemists, engineers, and procurement specialists, a thorough understanding of TBEP's characteristics is essential for leveraging its full potential.

Chemical and Physical Properties of TBEP

TBEP is characterized by its molecular formula C18H39O7P and a molecular weight of approximately 398.48 g/mol. It typically presents as a colorless to light yellow transparent liquid at room temperature, possessing a slightly sweet odor. Key physical properties that dictate its utility include:

  • Appearance: Colorless to light yellow transparent liquid.
  • Boiling Point: Approximately 215-228 °C at 4 mmHg, indicating good thermal stability for many processing applications.
  • Density: Around 1.006 g/mL at 25°C, making it slightly denser than water.
  • Refractive Index: Typically around 1.438 (nD20), a useful parameter for quality control.
  • Solubility: Soluble in many organic solvents and exhibits limited solubility in water, which influences its application in various media.

Key Industrial Applications of TBEP

The versatility of TBEP is underscored by its multifaceted roles in numerous industrial processes:

  • Plasticizer: TBEP is extensively used as a plasticizer for a variety of resins and elastomers. It enhances flexibility, durability, and processing characteristics, particularly in materials like PVC, cellulose acetate, epoxy resins, and polyurethanes. This makes it a key component for manufacturers looking to buy plasticizers that improve material performance.
  • Flame Retardant: As a phosphate ester, TBEP exhibits inherent flame-retardant properties. It is incorporated into plastics, textiles, and coatings to inhibit combustion and improve fire safety. This is especially valuable in applications where stringent fire safety regulations must be met.
  • Defoamer (Antifoaming Agent): TBEP is highly effective at controlling foam in various industrial processes. It is commonly used in the production of coatings, detergents, textiles, and synthetic rubber to prevent detrimental foam formation, thereby improving efficiency and product quality.
  • Floor Polishes and Adhesives: Its ability to act as a coalescent and plasticizer makes TBEP an excellent additive for floor polishes, contributing to a high-gloss, durable finish. In water-based adhesives, it improves processing and enhances bonding strength.
  • Viscosity Modifier: TBEP can reduce the viscosity of plastisols, simplifying handling and application in processes like coating and molding.
