Manufacturing Quality Control of Dibutyl phthalate
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Purity/Content Determination | Gas Chromatography (GC) | Utilizing gas chromatography to separate and quantitatively analyze dibutyl phthalate (DBP), typically using internal standard or external standard methods. It offers high sensitivity, good repeatability, and accuracy, and is a commonly used standard method for DBP content determination. |
| Purity/Content Determination | High-Performance Liquid Chromatography (HPLC) | Applicable for thermally unstable or non-volatile samples, using a reverse-phase chromatographic column to separate DBP and quantitative analysis with a UV detector (e.g., at wavelengths 220–254 nm). The method is simple to operate and has good reproducibility. |
| Impurity Analysis | Gas Chromatography-Mass Spectrometry (GC-MS) | Combines the separation capability of gas chromatography with the qualitative ability of mass spectrometry, effectively identifying and quantifying possible phthalate ester isomers or other organic impurities in DBP. It is suitable for trace impurity analysis in complex matrices. |
| Moisture Content | Karl Fischer Titration | Using volumetric or coulometric methods to determine trace moisture in DBP. This method has strong specificity and high accuracy, and is one of the standard methods for moisture determination in chemical products. |
| Acid Value | Acid-Base Titration Method | Using phenolphthalein as an indicator, titrating the free acid in the sample with a standard potassium hydroxide ethanol solution, calculating the acid value (mg KOH/g), which is used to evaluate acidic impurities generated from hydrolysis or oxidation of DBP. |
| Color | Platinum-Cobalt Colorimetric Method (or Visual Colorimetric Method) | Comparing the sample with standard platinum-cobalt solutions to determine its color (unit: Hazen or APHA), used to evaluate the appearance quality and degree of oxidation of DBP. |
| Density | Pycnometer Method or Hydrometer Method | Determining the density of DBP at a specified temperature (e.g., 20°C), serving as a physical property control indicator, used to assist in judging purity or adulteration. |
| Refractive Index | Refractometer Method | Using an Abbe refractometer to measure the refractive index of DBP at standard temperature, serving as a rapid identification and quality consistency control tool. |
