Manufacturing Quality Control of 2,3-DIHYDROXYPROPYL METHACRYLATE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | GC-FID | Quantification by comparison of peak area against a certified reference standard using flame ionization detection. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration based on the stoichiometric reaction of water with iodine and sulfur dioxide in pyridine/methanol medium. |
| Acid Value | Acid-Base Titration | Neutralization of free carboxylic acid groups with standardized potassium hydroxide solution using phenolphthalein indicator. |
| Hydroxyl Value | Acetylation Titration | Esterification of hydroxyl groups with acetic anhydride, followed by back-titration of unreacted anhydride with sodium hydroxide. |
| Color (APHA) | Visual Comparison or Spectrophotometry | Measurement of yellowness intensity by comparison to APHA color standards or absorbance at 430 nm in a 10-mm cell. |
| Density | Digital Density Meter | Determination of mass per unit volume at specified temperature using oscillating U-tube principle. |
| Refractive Index | Refractometry | Measurement of light bending angle at air-sample interface using calibrated Abbe refractometer at 20 degrees C. |
| Residue on Ignition | Gravimetric Analysis | Weighing of non-volatile residue remaining after controlled high-temperature ashing in a muffle furnace. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element quantification via atomic emission from plasma-excited sample aerosol; lead measured at characteristic wavelength. |
| Peroxide Value | Iodometric Titration | Oxidation of potassium iodide by peroxides to liberate iodine, followed by titration with standardized sodium thiosulfate. |
| Residual Solvents | GC-FID with Headspace | Separation and quantification of volatile organic solvents using headspace sampling and flame ionization detection. |
| Appearance | Visual Inspection | Assessment of clarity and absence of suspended particles or phase separation in a transparent container under controlled lighting. |
