Industrial Applications of tert-Butylphenyl diphenyl phosphate
| Industry | Application | Process |
|---|---|---|
| Plastics & Polymers | Flame-retardant plasticizer | Incorporated into polymers such as polyvinyl chloride (PVC) and polyurethane (PU) via compounding or melt extrusion to enhance flame retardancy and flexibility |
| Electrical & Electronics | Flame-retardant additive | Formulated into resin systems for wire and cable jackets, printed circuit board substrates, and other components to meet flame-retardant standards such as UL94 |
| Coatings & Adhesives | Flame-retardant synergist | Mixed with other formulation components in coatings or adhesives and applied via coating or spraying processes to impart flame-retardant properties to the finished film |
| Textiles | Co-agent for flame-retardant finishing | Used as a synergist in flame-retardant finishing baths and applied to fiber surfaces via padding-drying-curing processes to improve flame retardancy |
Manufacturing Quality Control of tert-Butylphenyl diphenyl phosphate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification using reversed-phase HPLC with UV detection at 210–230 nm, comparing peak area against a certified reference standard. |
| Acid Value | Acid-Base Titration | Neutralization of free acidic impurities with standardized KOH ethanol solution, using phenolphthalein or potentiometric endpoint detection. |
| Water Content | Karl Fischer Coulometric Titration | Electrochemical quantification of water via iodine generation and stoichiometric reaction with water in anhydrous methanol-based reagent. |
| Residue on Ignition | Gravimetric Analysis | Measurement of non-volatile inorganic residue after controlled high-temperature ashing (700–800 °C) and weighing. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Multi-element quantification by ionization in plasma and mass-selective detection with isotopic resolution and low detection limits. |
| Chloride Impurity | Ion Chromatography (IC) | Separation and conductivity detection of chloride ions after aqueous extraction and filtration. |
| Color (APHA) | Visual Spectrophotometry (APHA Scale) | Comparison of sample solution color intensity against platinum-cobalt standard solutions using spectrophotometric measurement at 455 nm. |
| Refractive Index | Refractometry | Measurement of light refraction angle at 20 °C using calibrated Abbe refractometer to assess purity and consistency. |
| Specific Gravity | Digital Density Meter | Determination of density relative to water at 20 °C via oscillating U-tube principle for batch consistency verification. |
| Volatile Impurities | GC-FID | Separation and flame-ionization detection of low-boiling organic impurities following headspace or direct injection. |
| Phosphate Ester Hydrolysis Products (e.g., phenol, tert-butanol) | GC-MS | Identification and quantification of thermal degradation or hydrolysis by-products using gas chromatographic separation and mass spectral confirmation. |
| Particulate Matter | Membrane Filtration & Microscopy | Filtration through 0.45 µm membrane followed by microscopic examination or particle counting per USP <788>. |
