Industrial Applications of Tri-o-cresyl Phosphate
| Industry | Application | Process |
|---|---|---|
| Plastics Industry | Plasticizer for polyvinyl chloride (PVC) | Used as a primary plasticizer or in combination with phthalates in compounding, extrusion, and calendering processes for flexible PVC products (e.g., cable sheaths, artificial leather, hoses) |
| Flame-Retardant Materials | Organophosphorus flame retardant | Incorporated into epoxy resins, phenolic resins, and unsaturated polyester resins via blending or reactive incorporation during curing to impart self-extinguishing properties |
| Coatings and Inks | Film-forming aid and flame-retardant modifier | Uniformly dispersed in alkyd resin coatings, acrylic coatings, and printing inks through high-speed dispersion and grinding processes |
| Adhesives | Flame-retardant and plasticizing synergist | Added as a functional additive to hot-melt adhesives and rubber-based adhesives; incorporated via melt mixing followed by coating or lamination |
| Textile Auxiliaries | Flame-retardant finishing agent | Applied to cotton and polyester-cotton blended fabrics via pad-dry-cure processing; used synergistically with nitrogen-containing flame-retardant synergists (e.g., melamine derivatives) |
Manufacturing Quality Control of Tri-o-cresyl Phosphate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantitative determination based on peak area comparison against a certified reference standard using a non-polar capillary column. |
| Acid Value | Acid-Base Titration with KOH in ethanol | Neutralization of acidic impurities by standardized potassium hydroxide solution, using phenolphthalein indicator. |
| Water Content | Karl Fischer Coulometric Titration | Electrochemical generation and reaction of iodine with water in anhydrous methanol-based reagent; water quantified via coulometric current integration. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement at 430 nm | Comparison of sample color intensity to platinum-cobalt standards or measurement of absorbance at 430 nm in a 10-mm cell. |
| Density at 20 degC | Digital Density Meter (Oscillating U-tube principle) | Measurement of sample density based on resonant frequency shift of a vibrating U-shaped tube filled with the liquid. |
| Refractive Index at 20 degC | Abbe Refractometer | Determination of refractive index by measuring the critical angle of total internal reflection at the prism-sample interface. |
| Chloride Content | Ion Chromatography (IC) with conductivity detection | Separation of chloride ions on an anion-exchange column followed by quantitative detection via suppressed conductivity. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) after wet ashing | Digestion of organic matrix followed by flame or graphite furnace AAS measurement of lead absorption at 283.3 nm. |
| Non-Volatile Residue | Gravimetric Analysis (Weight Loss on Drying) | Evaporation of sample under controlled temperature and vacuum, followed by weighing of residual solids. |
| Phosphate Ester Isomers Profile | Gas Chromatography-Mass Spectrometry (GC-MS) | Separation and identification of ortho-, meta-, and para-isomers based on retention time and characteristic mass fragmentation patterns. |
| Residual Phenol | High Performance Liquid Chromatography (HPLC) with UV detection | Separation on reversed-phase C18 column and quantification of phenol at 270 nm using external calibration. |
| Flash Point | Pensky-Martens Closed Cup Tester | Determination of lowest temperature at which vapors above the sample ignite momentarily when exposed to a test flame under standardized conditions. |
