Manufacturing Quality Control of Propanoic acid, 2-hydroxy-, C12-15-alkyl esters
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the sample's color, transparency, and presence of suspended particles or sediment under natural light or standard light sources. It should typically be a colorless to pale yellow transparent liquid. |
| Color | Platinum-Cobalt Colorimetry (e.g., ASTM D1209 or GB/T 3143) | Compare the sample with standard platinum-cobalt solutions to determine its color value (expressed in Hazen units), assessing product purity and oxidation level. |
| Acid Value | Acid-Base Titration (e.g., GB/T 601 or ISO 2114) | Determine the free acid content in the sample using phenolphthalein as an indicator, titrating with standardized potassium hydroxide ethanol solution. The result is expressed in mg KOH/g. |
| Hydroxyl Value | Acetylation Method (e.g., GB/T 7383 or ASTM D4274) | React the sample's hydroxyl groups with acetic anhydride, then back-titrate the unreacted acetic anhydride with an alkali solution. Calculate the hydroxyl value (mg KOH/g) to reflect residual alcohol content. |
| Water Content | Karl Fischer Titration (e.g., GB/T 6283 or ASTM E1064) | Determine the water content in the sample by quantitatively reacting it with Karl Fischer reagent using potentiometric or volumetric titration. The result is expressed as a percentage (%). |
| Purity/Main Component Content | Gas Chromatography (GC, e.g., GB/T 11538 or internal method) | Separate the sample components using a capillary column gas chromatography, and quantify the main peak (C12-13 alcohol lactate ester) content (%) via area normalization or internal standard methods. |
| Residual Solvents | Gas Chromatography (headspace injection or direct injection) | Detect organic solvents (e.g., toluene, acetone) that may remain from the production process, based on pharmacopoeia or industry standards for limit values. |
| Density | Densitometer Method or Vibrating Density Meter (e.g., GB/T 2540 or ASTM D4052) | Determine the sample density (g/cm³) at a specified temperature (usually 20°C or 25°C), used as an auxiliary indicator for composition consistency. |
| Refractive Index | Refractometer Method (e.g., GB/T 614 or ASTM D1218) | Determine the refractive index of the sample to sodium light (589.3 nm) at a standard temperature, serving as an auxiliary quality control indicator. |
| pH Value (Aqueous Solution) | pH Meter Method | Prepare a water solution of the sample at a certain concentration (e.g., 10% w/w), and measure its pH value using a calibrated pH meter to assess acidity or alkalinity. |
