Manufacturing Quality Control of Diethyl phthalate
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Purity/Content Determination | Gas Chromatography (GC) | Utilizing gas chromatography to separate and quantitatively analyze diethyl phthalate (DEP) samples, typically using FID (Flame Ionization Detector), with area normalization or external standard methods for quantification. Suitable for precise determination of the main component content in high-purity samples. |
| Purity/Content Determination | High-Performance Liquid Chromatography (HPLC) | Using a reverse-phase C18 column and UV detector (e.g., at wavelengths 220–254 nm) for separation and quantification of DEP. Applicable for analyzing samples containing non-volatile impurities or thermally unstable components. |
| Moisture Content | Karl Fischer Titration | Based on the reaction between iodine and sulfur dioxide in a pyridine/methanol system with water, using coulometric or volumetric methods to accurately determine trace moisture in DEP. It is a standard method for measuring moisture in organic solvents. |
| Acid Value | Acid-Base Titration | Dissolving the sample in neutral ethanol, using phenolphthalein as an indicator, and titrating with standardized sodium hydroxide solution to determine free acid content. The acid value is calculated as mg KOH/g, used to evaluate the amount of residual acidic impurities (e.g., phthalic acid) in DEP. |
| Color | Visual Colorimetry or Platinum-Cobalt Colorimetry | Placing the sample in a colorimetric tube and comparing its color depth with standard platinum-cobalt solutions, expressed in Hazen (or APHA) units. Used to evaluate product appearance quality and discoloration caused by oxidation or impurities. |
| Volatile Impurities | Gas Chromatography-Mass Spectrometry (GC-MS) | Separating components via GC and identifying and semi-quantifying them using MS. Capable of detecting and determining residual low-boiling-point solvents, by-products, or other phthalate ester impurities in DEP, with high sensitivity and specificity. |
| Density | Pycnometer Method or Hydrometer Method | Determining the density of DEP at a specified temperature (e.g., 20°C) using a digital densimeter or glass pycnometer. Useful for judging purity or batch consistency. |
| Refractive Index | Refractometer Method | Measuring the refractive index of DEP using an Abbe refractometer at standard temperature. Acts as a rapid identification and quality control physical parameter. |
