Manufacturing Quality Control of DI-TERT-BUTYL PHOSPHITE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantifies main component peak area relative to calibration curve using volatile, thermally stable derivatives. |
| Acid Value | Acid-Base Titration with KOH in ethanol | Measures free acidic impurities by neutralization with standardized alcoholic KOH solution. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemically determines water via iodine generation and stoichiometric reaction with sample water. |
| Color | APHA Color Scale (Visual or Spectrophotometric) | Compares sample color intensity against platinum-cobalt standard solutions at 455 nm. |
| Density | Digital Density Meter (Oscillating U-tube) | Determines mass per unit volume from resonant frequency shift of vibrating U-shaped tube filled with sample. |
| Refractive Index | Refractometry (20 C) | Measures bending of light at air-sample interface to infer molecular concentration and purity. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Quantifies non-volatile inorganic residue after controlled high-temperature ashing and weighing. |
| Heavy Metals (as Pb) | ICP-OES | Simultaneously detects trace metal elements by measuring characteristic atomic emission wavelengths after plasma atomization. |
| Chloride Content | Potentiometric Titration with AgNO3 | Detects chloride ions via silver nitrate titration monitored by silver-ion selective electrode endpoint. |
| Phosphorus Content | UV-Vis Spectrophotometry (Ammonium Molybdate Method) | Measures phosphomolybdate complex absorbance at ~820 nm after oxidative digestion and color development. |
| Volatility Loss | Thermogravimetric Analysis (TGA) | Determines weight loss under controlled nitrogen atmosphere up to 200 C to assess low-boiling impurities. |
| Appearance | Visual Inspection (in glass container) | Assesses clarity and presence of suspended particles or phase separation under controlled lighting conditions. |
