Industrial Applications of Diphenyl isopropylphenyl phosphate
| Industry | Application | Process |
|---|---|---|
| Plastics Industry | Flame Retardant Plasticizer | Used as an additive flame retardant and plasticizer in the processing of polymeric materials such as polyvinyl chloride (PVC) and polyurethane foam to enhance flame resistance and flexibility |
| Electronics & Electrical Equipment | Processing Aid for Electronic Component Encapsulants | Incorporated into insulating materials and encapsulating resins for electronic devices to improve thermal resistance, flame retardancy, and electrical insulation properties |
| Textile Industry | Flame Retardant Finishing Agent | Applied in flame retardant finishing processes for textiles—typically via padding or coating—to impart flame retardancy to fabrics |
| Coatings Industry | Flame Retardant Additive for Coatings | Added to fire-resistant coating formulations to enhance coating stability and flame retardant performance at elevated temperatures |
Manufacturing Quality Control of Diphenyl isopropylphenyl phosphate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantifies main component by retention time and peak area against calibrated standard. |
| Acid Value | Acid-Base Titration with KOH in ethanol | Measures free acidic impurities by titration with standardized potassium hydroxide solution. |
| Moisture Content | Karl Fischer Coulometric Titration | Determines water content via electrochemical iodine generation proportional to water present. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement at 455 nm | Evaluates yellowness by comparing sample absorbance to APHA color scale standards. |
| Density at 25 C | Digital Density Meter (Oscillating U-tube principle) | Measures mass per unit volume based on resonant frequency shift of vibrating tube filled with sample. |
| Refractive Index at 20 C | Refractometry (Abbe refractometer) | Determines ratio of light velocity in air vs. sample using critical angle measurement. |
| Non-Volatile Residue | Gravimetric Analysis (Evaporation and Weighing) | Quantifies residue after controlled evaporation of specified sample mass under defined conditions. |
| Heavy Metals (as Pb) | ICP-OES (Inductively Coupled Plasma Optical Emission Spectrometry) | Detects trace metal elements by measuring characteristic atomic emission wavelengths after plasma atomization. |
| Chloride Content | Potentiometric Titration with AgNO3 | Measures chloride ions via silver nitrate titration monitored by silver electrode potential change. |
| Transparency | Visual Inspection in Nessler Cylinder | Assesses clarity by observing absence of suspended particles against black/white background. |
| Flash Point | Pensky-Martens Closed Cup Tester | Determines lowest temperature at which vapors ignite momentarily when exposed to flame under standardized conditions. |
| Viscosity at 25 C | Rotational Viscometry (e.g., Brookfield) | Measures resistance to flow via torque required to rotate spindle in sample at controlled temperature. |
