Manufacturing Quality Control of 4-Ethylbenzonitrile
| 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 calibrated column and flame ionization detector. |
| Water Content | Karl Fischer Titration | Electrochemical titration where iodine reacts stoichiometrically with water in a methanol-based solvent, with endpoint detected amperometrically. |
| Residue on Ignition | Gravimetric Analysis | Sample is incinerated at 700-800 C to oxidize organic matter; inorganic residue is weighed after cooling in a desiccator. |
| Color (APHA) | Visual Comparison or Spectrophotometry | Comparison of sample solution color intensity against platinum-cobalt standard solutions using APHA scale, measured at 430 nm if spectrophotometric. |
| Acidity (as H2SO4) | Acid-Base Titration | Titration with standardized sodium hydroxide solution using phenolphthalein indicator; acidity calculated as sulfuric acid equivalent. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of total heavy metals after wet digestion by measuring absorbance of ground-state atoms at element-specific wavelengths. |
| Chlorinated Impurities | Gas Chromatography-Mass Spectrometry (GC-MS) | Separation and identification of chlorinated by-products via retention time and mass spectral fragmentation patterns. |
| Related Substances | High Performance Liquid Chromatography (HPLC) with UV detection | Separation on reversed-phase column and quantification of impurities using UV absorbance at 220 nm relative to main peak. |
| Boiling Point | Distillation (ASTM D1078) | Determination of temperature at which vapor pressure equals atmospheric pressure, measured using calibrated distillation apparatus. |
| Density at 20 C | Oscillating U-tube Densitometry | Measurement of sample density based on resonant frequency shift of a vibrating U-shaped glass tube filled with sample. |
| Refractive Index at 20 C | Refractometry | Determination of ratio of speed of light in air versus sample using critical angle measurement with sodium D-line illumination. |
| Non-Volatile Residue | Evaporation and Gravimetry | Sample is evaporated to dryness under controlled conditions; residue is weighed after drying at 105 C for 1 hour. |
