For any chemical compound to be effectively utilized in industrial applications, a thorough understanding of its chemical and physical properties is indispensable. Tert-Butylphenyl Diphenyl Phosphate (BPDP), identified by CAS number 56803-37-3, is a complex organophosphorus compound that offers unique advantages, particularly as a flame retardant and plasticizer. NINGBO INNO PHARMCHEM CO.,LTD., a dedicated chemical manufacturer, provides essential insights into these properties, guiding researchers and procurement specialists in their selection and application.

Molecular Structure and Basic Properties

BPDP has the molecular formula C22H23O4P, with a molecular weight of approximately 382.39 g/mol. Its chemical structure, featuring a diphenyl phosphate backbone with a tert-butylphenyl group, is key to its performance. This structure influences its thermal stability, hydrolysis resistance, and compatibility with various polymer systems. From a physical standpoint, it is typically described as a clear, transparent liquid, a characteristic that facilitates its incorporation into liquid formulations or melt processing of polymers.

Key Physical and Chemical Characteristics

Understanding the specific properties of BPDP is critical for optimal application:

  • Appearance: Clear transparent liquid. This physical state is advantageous for homogeneous mixing in liquid formulations or during polymer extrusion processes.
  • Density: Typically around 1.150-1.182 at 20℃. Density is an important factor for volumetric calculations and material handling.
  • Viscosity: Measured at 25℃, the viscosity is usually in the range of 70-100 mPa.s. This parameter influences its flowability and ease of application.
  • Acidity: A low acidity (0.1 mgKOH/g max) indicates good stability and minimal corrosive potential, which is vital for long-term material integrity.
  • Water Content: Typically very low (0.1% max), ensuring good hydrolysis resistance and performance in humid environments.
  • Color: Usually rated by APHA, with values ideally below 80, signifying high purity and minimal coloration.
  • Free Phenol Content: Kept below 0.1%, which is important for both safety and product performance.

Solubility and Stability

As an aryl phosphate, BPDP exhibits moderate solubility in common organic solvents such as acetone, ethyl acetate, and methanol. This solubility profile is important for its use in various chemical processes and formulations. Crucially, BPDP demonstrates excellent thermal stability and hydrolysis resistance, making it suitable for demanding applications and ensuring a long service life for the end products. These properties are essential for manufacturers seeking reliable chemical suppliers who can guarantee product integrity.

Safety Considerations and Manufacturer Support

While BPDP offers significant advantages, like all industrial chemicals, it requires proper handling. Scientific literature may indicate potential toxicological properties, underscoring the importance of adhering to safety protocols and consulting Material Safety Data Sheets (MSDS). Reputable manufacturers, such as NINGBO INNO PHARMCHEM CO.,LTD., provide comprehensive technical data and support to ensure the safe and effective use of their products. When planning to buy Tert-Butylphenyl Diphenyl Phosphate, engaging with a manufacturer can provide not just the chemical but also the expertise needed for its successful implementation.

In summary, the chemical properties of Tert-Butylphenyl Diphenyl Phosphate are fundamental to its role as a high-performance additive. Its clarity, stability, and solubility, combined with its flame-retardant and plasticizing capabilities, make it an invaluable component in modern material science. Understanding these characteristics empowers formulators and engineers to maximize its potential in diverse industrial applications.
