Manufacturing Quality Control of 5-CHLORO-2-METHYLPHENYL ISOCYANATE
| 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. |
| 5-Chloro-2-methylphenyl isocyanate content | High-Performance Liquid Chromatography (HPLC) with UV detection | Separation on a reversed-phase C18 column and quantification at 230 nm using external standard calibration. |
| Residual Solvents (e.g., toluene, xylene) | Headspace Gas Chromatography (HS-GC) with FID | Volatile solvent quantification via equilibrium vapor phase analysis after thermal equilibration of sample headspace. |
| Moisture Content | Karl Fischer Titration (coulometric mode) | Electrochemical titration where iodine generated coulometrically reacts stoichiometrically with water in the sample. |
| Acid Number | Acid-Base Titration with NaOH standard solution | Neutralization of acidic impurities (e.g., hydrolyzed isocyanate to amine + CO2) using phenolphthalein endpoint detection. |
| Chloride Ion Impurity | Ion Chromatography (IC) with conductivity detection | Separation of anions on an ion-exchange column followed by quantitative detection of Cl- via suppressed conductivity. |
| Heavy Metals (Pb, Cd, Hg, Cr) | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Atomization and excitation of metals in high-temperature plasma; quantification via element-specific emission wavelengths. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement | Comparison of sample color intensity against platinum-cobalt standard solutions at 455 nm wavelength. |
| 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 sample. |
| Refractive Index at 20 degC | Digital Refractometer | Determination of refractive index via critical angle measurement of light passing through the sample-prism interface. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Weighing before and after high-temperature ashing to quantify inorganic residue remaining after organic matrix combustion. |
| Isocyanate Content (NCO %) | Modified ASTM D2572 (Reaction with dibutylamine + back-titration) | NCO groups react quantitatively with excess dibutylamine; unreacted amine is titrated with HCl to determine NCO concentration. |
