Manufacturing Quality Control of PROPIONALDEHYDE DIETHYL ACETAL
| 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 detector. |
| Water Content | Karl Fischer Titration | Electrochemical titration where iodine reacts stoichiometrically with water in anhydrous methanol/pyridine medium. |
| Acidity (as Acetic Acid) | Acid-Base Titration with NaOH | Neutralization of acidic impurities using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement at 430 nm | Comparison of sample color to APHA platinum-cobalt standards or measurement of absorbance at 430 nm in a 10 cm cell. |
| Density at 20 degC | Digital Density Meter (Oscillating U-tube) | Measurement of oscillation period of a U-shaped tube filled with sample, correlated to density via calibration with water and air. |
| Refractive Index at 20 degC | Abbe Refractometer | Determination of refractive index by measuring the critical angle of total internal reflection at the prism-sample interface. |
| Residue on Evaporation | Gravimetric Analysis | Evaporation of a measured sample volume to dryness at 105 degC followed by weighing of non-volatile residue. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of trace metal content after wet digestion and atomization in a graphite furnace or flame. |
| Non-Volatile Matter | Gravimetric Analysis | Evaporation of a known mass of sample to constant weight at 105 degC and calculation of residual solids. |
| Aldehyde Impurities (e.g., Propionaldehyde) | Gas Chromatography (GC) with FID detection | Separation and quantification of volatile aldehyde impurities using a polar capillary column and flame ionization detection. |
| Ethanol Content | Gas Chromatography (GC) with FID detection | Quantitative analysis of residual ethanol using internal standard (e.g., n-propanol) and appropriate column selectivity. |
| Chloride Content | Ion Chromatography (IC) or Potentiometric Titration with AgNO3 | Separation and conductivity detection of chloride ions (IC) or argentometric titration forming AgCl precipitate. |
