Manufacturing Quality Control of 4-Butylphenol
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies 4-tert-butylphenol peak area relative to a calibrated standard curve using flame ionization detection. |
| Water Content | Karl Fischer Titration | Measures water via coulometric or volumetric titration with iodine generated in situ, based on the stoichiometric reaction of water with iodine and sulfur dioxide. |
| Residue on Ignition | Gravimetric Analysis | Determines non-volatile inorganic impurities by ignition at 700-800 C and weighing the residual ash. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals (e.g., Pb, Cd, Hg, As) after acid digestion by measuring elemental absorption of specific wavelengths of light. |
| Chloride Content | Potentiometric Titration with Silver Nitrate | Measures chloride ions by titration with AgNO3 using a silver indicator electrode; endpoint detected by potential change. |
| Acidity (as p-Toluenesulfonic Acid) | Acid-Base Titration with NaOH | Determines acidic impurities by titration with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement | Compares sample color to platinum-cobalt standard solutions visually or measures absorbance at 455 nm against APHA scale. |
| Melting Point | Capillary Melting Point Determination | Measures temperature range at which solid transitions to liquid using calibrated capillary apparatus under controlled heating rate. |
| Refractive Index | Refractometry | Determines ratio of speed of light in air vs. sample at 20 C using Abbe refractometer calibrated with distilled water. |
| Specific Gravity | Pycnometry or Digital Density Meter | Measures ratio of sample density to water density at specified temperature (typically 25/25 C) using calibrated glass pycnometer or oscillating U-tube densitometer. |
| Non-Volatile Residue | Evaporation and Gravimetry | Quantifies residue after evaporating fixed volume under controlled conditions (e.g., 105 C, 1 h) and weighing dried residue. |
| Organic Impurities (Related Substances) | High Performance Liquid Chromatography (HPLC) with UV detection | Separates and quantifies structurally related compounds (e.g., isomers, degradation products) using reversed-phase column and UV absorbance at 275 nm. |
