Overview
Di-tert-butyl phosphate (DTBP) is an organophosphate compound widely utilized in industrial applications due to its flame-retardant and plasticizing properties. It is commonly incorporated into polymers and coatings to enhance fire resistance and flexibility. DTBP is synthesized through the esterification of phosphoric acid with tert-butanol, resulting in a stable, low-volatility liquid. As a specialty chemical, DTBP is valued for its ability to improve material performance without significantly altering other properties. Its compatibility with various organic solvents makes it versatile for formulations in plastics, adhesives, and coatings. The compound is typically handled in controlled environments to ensure safety and efficacy.
Physical and Chemical Properties
Di-tert-butyl phosphate is a colorless to pale yellow liquid with a density of 1.02 g/cm³ at 20°C. It has a boiling point of approximately 120°C at reduced pressure (10 mmHg) and is soluble in common organic solvents such as ethanol and acetone, though it exhibits low solubility in water. These properties make it suitable for integration into hydrophobic matrices like plastics and resins. The compound's molecular structure, featuring two tert-butyl groups attached to a phosphate core, contributes to its thermal stability and flame-retardant efficacy. Its low volatility ensures minimal evaporation during processing, making it a reliable additive in high-temperature applications. DTBP's chemical inertness under normal conditions further enhances its utility in diverse industrial settings.
Main Applications
DTBP is primarily employed as a flame retardant in plastics, coatings, and adhesives, where it helps reduce flammability and slow combustion. Its plasticizing effects are also leveraged to improve the flexibility and workability of polymeric materials. In the automotive and electronics industries, DTBP is used to enhance the fire safety of components like wire insulation and circuit boards. Additionally, the compound finds niche applications in specialty coatings for textiles and construction materials, where flame resistance is critical. Its compatibility with other additives allows for tailored formulations to meet specific performance requirements. The demand for DTBP is driven by stringent fire safety regulations across multiple sectors, particularly in regions with high safety standards.
Safety and Storage
Handling Di-tert-butyl phosphate requires adherence to safety protocols to mitigate risks associated with chemical exposure. Workers should use personal protective equipment (PPE), including gloves, goggles, and respirators, to prevent skin contact, eye irritation, or inhalation of vapors. The compound should be stored in a cool, dry, well-ventilated area, away from heat sources and open flames to avoid combustion hazards. Spills should be contained using inert absorbents and disposed of in accordance with local regulations. DTBP is not classified as highly toxic, but prolonged exposure should be avoided. Safety data sheets (SDS) provided by suppliers must be reviewed to ensure compliance with workplace safety standards and environmental guidelines.
B2B Procurement Guide
When procuring Di-tert-butyl phosphate, B2B buyers should prioritize suppliers with verified certifications (e.g., ISO, REACH) to ensure product quality and regulatory compliance. Key specifications to confirm include CAS number (2528-36-1), purity levels (typically >95%), and packaging options (e.g., drums, totes). Bulk purchases often yield cost savings, but storage capacity and shelf life should be considered. Buyers are advised to request samples for quality testing and evaluate supplier reliability through customer reviews or industry references. Transparent communication about lead times, minimum order quantities, and logistics is essential to align procurement with production schedules. Regional price variations may occur due to raw material availability and transportation costs.
