Manufacturing Quality Control of 4-CHLORO-2-BUTANONE
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Content Determination | Gas Chromatography (GC) | Capillary column gas chromatography with a hydrogen flame ionization detector (FID) is used. The external standard or internal standard method is applied for quantitative analysis of the main component in β-chlorobutanone. It offers high sensitivity, good separation, and excellent repeatability. |
| Impurity Analysis | Gas Chromatography-Mass Spectrometry (GC-MS) | Combines the separation ability of gas chromatography with the qualitative capability of mass spectrometry to identify and semi-quantitatively analyze organic impurities (such as byproducts and degradation products) in β-chlorobutanone. Suitable for trace impurity identification. |
| Water Content | Karl Fischer Titration | Iodine reacts quantitatively with water in solvents such as methanol/ethylene glycol in the presence of sulfur dioxide. The water content is determined by potentiometric titration. This method is suitable for detecting trace amounts of water with high accuracy. |
| Acid Value / Acidity | Acid-Base Titration | The sample is dissolved in an appropriate solvent (e.g., ethanol), and free acids are titrated with a standard sodium hydroxide solution to calculate the acid value (mg KOH/g). Used to assess acidic degradation products that may form during storage. |
| Color | Visual Color Comparison or Spectrophotometry | Compare the sample with standard color solutions or measure absorbance at a specific wavelength (e.g., 420 nm) to evaluate color depth, which reflects purity and oxidation level. |
| Density | Densitometer Method or Pycnometer Method | Measure the mass per unit volume using a densitometer or a constant-temperature pycnometer. Used to verify physical properties and assist in assessing material purity. |
| Refractive Index | Abbe Refractometer Method | Measure the refractive index of the sample at a standard temperature (typically 20°C) using an Abbe refractometer. Serves as an auxiliary indicator for purity and identity verification. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Residual solvents are volatilized by heating the sample, and the headspace gas is sampled for analysis. Commonly used to detect residual solvents such as toluene, acetone, and ethanol from the production process. |
