Manufacturing Quality Control of DIPROPYL PHTHALATE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantitative determination based on peak area comparison against a certified reference standard using a polar capillary column. |
| Acid Value | Acid-Base Titration with KOH in ethanol | Neutralization of free carboxylic acid impurities by standardized potassium hydroxide solution, using phenolphthalein indicator. |
| Water Content | Karl Fischer Coulometric Titration | Electrochemical generation and reaction of iodine with water in anhydrous methanol-based reagent; water quantified by coulombs consumed. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement at 430 nm | Comparison of sample color intensity to APHA platinum-cobalt standards or absorbance measurement at 430 nm in a 10-mm cell. |
| Density at 20 C | Digital Density Meter (Oscillating U-tube principle) | Measurement of sample density based on resonant frequency shift of a vibrating U-shaped tube filled with the liquid. |
| Refractive Index at 20 C | Abbe Refractometer | Determination of refractive index by measuring the critical angle of total internal reflection at the prism-sample interface. |
| Non-Volatile Residue | Gravimetric Analysis (Evaporation and Weighing) | Evaporation of a known sample mass under controlled temperature and vacuum, followed by weighing of residual solids. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) after wet digestion | Quantification of total heavy metals after nitric-perchloric acid digestion, using air-acetylene flame AAS at appropriate wavelengths. |
| Residual Chlorides | Ion Chromatography (IC) with conductivity detection | Separation and quantification of chloride ions on an anion-exchange column with suppressed conductivity detection. |
| Di-n-Propyl Phthalate Isomer Content | Gas Chromatography-Mass Spectrometry (GC-MS) | Identification and quantification of structural isomers (e.g., di-n-propyl vs. di-isopropyl) using retention time and characteristic mass fragments. |
| Aldehyde Impurities (e.g., propionaldehyde) | Gas Chromatography with FID or Headspace GC-FID | Derivatization-free headspace or direct GC analysis targeting volatile aldehyde impurities based on retention and response. |
| Residual Solvents (e.g., methanol, acetone) | Headspace Gas Chromatography (HS-GC) with FID | Quantitative analysis of low-boiling solvents via equilibrium partitioning into headspace, followed by GC separation and FID detection. |
