Manufacturing Quality Control of 4-Fluorostyrene
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) | Quantitative separation and detection of 4-fluorostyrene using a capillary column and flame ionization detector. |
| Water Content | Karl Fischer Titration | Electrochemical titration based on the reaction of iodine with water in a methanol-based reagent. |
| Residue on Evaporation | Gravimetric Analysis | Evaporation of a known sample mass followed by weighing of non-volatile residue. |
| Acidity (as HCl) | Acid-Base Titration | Titration with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Chlorinated Impurities (e.g., alpha-chloro-4-fluorotoluene) | Gas Chromatography-Mass Spectrometry (GC-MS) | Separation by GC coupled with mass spectral identification and quantification of chlorinated by-products. |
| Aldehyde Impurities (e.g., 4-fluorobenzaldehyde) | High-Performance Liquid Chromatography (HPLC) | Reverse-phase HPLC with UV detection at 254 nm for separation and quantification. |
| Heavy Metals (as Pb) | Inductively Coupled Plasma-Optical Emission Spectrometry (ICP-OES) | Atomization and excitation of metals in argon plasma, followed by element-specific emission measurement. |
| Color (APHA) | Visual Comparison or Spectrophotometry | Comparison of sample color against platinum-cobalt standard solutions or measurement of absorbance at 430 nm. |
| Refractive Index | Refractometry | Measurement of light refraction angle through the liquid sample at specified temperature (20 C). |
| Specific Gravity | Pycnometry | Determination of density ratio relative to water using a calibrated pycnometer. |
| Unsaturation (Bromine Number) | Bromination Titration | Addition of bromine to double bonds followed by back-titration of excess bromine with sodium thiosulfate. |
| Residual Solvents (e.g., toluene, methanol) | Gas Chromatography (GC) with Headspace Sampling | Headspace equilibration followed by GC-FID analysis for volatile organic impurities. |
