Manufacturing Quality Control of 2-Methyl-2,4-pentanediol
| Detection Item | Common Testing Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the sample's color and transparency under natural light or standard illumination to determine whether it is a colorless to pale yellow transparent liquid. |
| Content (Purity) | Gas Chromatography (GC) | Utilize capillary column gas chromatography with flame ionization detection (FID). Qualitative analysis is based on retention time, while quantitative analysis is performed using area normalization or external standard method. The main component content is typically required to be ≥98% or higher. |
| Moisture Content | Karl Fischer Titration | Based on the quantitative reaction between iodine and sulfur dioxide in the presence of pyridine and methanol, water is determined via coulometric or volumetric titration. This method is suitable for trace water analysis. |
| Density | Density Meter Method / Specific Gravity Bottle Method | Measure the liquid density using a density meter or constant-temperature specific gravity bottle at a specified temperature (e.g., 20°C) to verify material consistency. |
| Refractive Index | Refractometry (Abbe Refractometer) | Determine the refractive index (n20D) at a standard temperature (e.g., 20°C) using an Abbe refractometer, serving as a physical constant for identification and purity assessment. |
| Acid Value | Acid-Base Titration | Titrate free acids in the sample using standardized sodium hydroxide solution in neutral ethanol as solvent. Calculate the milligrams of KOH consumed per gram of sample (mg KOH/g), reflecting the level of acidic impurities. |
| Colorimetry | Platinum-Cobalt Colorimetric Method | Visually or instrumentally compare the sample with platinum-cobalt standard color scales to assess the intensity of color, typically expressed in APHA or Pt-Co units. |
| Impurity Analysis | Gas Chromatography-Mass Spectrometry (GC-MS) | Combine GC separation capability with MS qualitative identification to detect organic impurities such as isomers, by-products, and degradation products. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Heat the sample in a headspace vial to volatilize residual solvents, then inject into the GC system for detection. Commonly used to analyze process-related solvents such as methanol, acetone, benzene, etc. |
| Residue on Ignition (Sulfate Ash) | Gravimetric Method | Treat the sample with sulfuric acid followed by high-temperature ignition, then weigh the residual inorganic matter. Express results as a percentage to evaluate total inorganic impurities. |
