Manufacturing Quality Control of 1,3-Propanediol, 2,2-bis(hydroxymethyl)-, allyl ether
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component peak area relative to calibration curve using internal or external standard. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between iodine, sulfur dioxide, and water in methanol/pyridine medium. |
| Acid Number | Acid-Base Titration with NaOH | Determines acidic impurities by titration with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Hydroxyl Value | Acetylation followed by Titration | Measures hydroxyl groups via acetic anhydride esterification, then back-titration of unreacted anhydride with NaOH. |
| Color (APHA) | Visual Comparison or Spectrophotometry | Compares sample color to platinum-cobalt standard solutions at 455 nm or uses APHA scale spectrophotometrically. |
| Density at 20 C | Digital Density Meter | Determines mass per unit volume using oscillating U-tube principle calibrated with air and water standards. |
| Refractive Index at 20 C | Refractometry | Measures bending of light through sample at specified temperature using calibrated refractometer. |
| Residue on Ignition | Gravimetric Analysis | Determines non-volatile inorganic residue after controlled high-temperature ashing and weighing. |
| Chloride Content | Ion Chromatography (IC) | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals after acid digestion by measuring atomic absorption at characteristic wavelength. |
| Allyl Ether Content | Gas Chromatography-Mass Spectrometry (GC-MS) | Identifies and quantifies allyl ether isomers based on retention time and characteristic mass fragments. |
| Viscosity at 25 C | Rotational Viscometry | Measures resistance to flow under shear using calibrated spindle rotating in sample at controlled temperature. |
