Manufacturing Quality Control of 2,2,4-Trimethyl-1,3-pentanediol
| Test Item | Common Test Method | Method Overview |
|---|---|---|
| Purity | Gas Chromatography (GC) | Using capillary column gas chromatography with an FID detector for separation and quantitative analysis of the sample. The purity of 2,2,4-trimethyl-1,3-pentanediol is calculated by peak area normalization or internal standard method. |
| Water Content | Karl Fischer Titration | Quantitative reaction between Karl Fischer reagent and water in the sample. The water content is determined by potentiometric or coulometric titration, suitable for accurate determination of trace moisture. |
| Color | Platinum-Cobalt Color Scale (Pt-Co) | The sample is visually compared with standard platinum-cobalt solutions under the same conditions, or measured using a spectrophotometer to evaluate whether the product color meets quality requirements. |
| Acid Value | Acid-Base Titration | Using phenolphthalein as an indicator, the free acids in the sample are titrated with a standard ethanolic potassium hydroxide solution. The acid value is expressed as milligrams of KOH consumed per gram of sample (mg KOH/g), reflecting the content of acidic impurities. |
| Hydroxyl Value | Acetylation Method + Back Titration | The sample reacts with excess acetic anhydride to acetylate the hydroxyl groups, and the unreacted acetic acid is back-titrated with a standard NaOH solution. The hydroxyl content is determined and expressed as mg KOH/g. |
| Boiling Range/Boiling Point | Distillation Method (Atmospheric or Reduced Pressure) | Using a standard distillation apparatus, the temperature range from initial boiling point to dry point is measured under specified pressure. This test is used to assess volatile impurities and confirm whether the boiling point of the main component meets specifications. |
| Appearance | Visual Inspection | The sample is observed under natural light or standard lighting conditions to assess physical characteristics such as clarity, presence of suspended matter, and color. It serves as a basic physical quality control parameter. |
| Density | Density Meter Method or Oscillating U-Tube Method | The sample density is measured using a glass hydrometer or digital oscillating U-tube densitometer at a specified temperature (e.g., 20°C or 25°C), used for material identification and quality consistency control. |
