Manufacturing Quality Control of ETHYLENE GLYCOL BIS(3-AMINOPROPYL) ETHER
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantitative determination based on peak area comparison against a certified reference standard using a polar capillary column. |
| Water Content | Karl Fischer Titration (Coulometric mode) | Electrochemical titration where iodine generated in situ reacts stoichiometrically with water; endpoint detected amperometrically. |
| Amine Value | Acid-Base Titration (Non-aqueous titration with HClO₄ in glacial acetic acid) | Titration of primary and secondary amine groups with standardized perchloric acid; endpoint detected potentiometrically or by indicator. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement (430 nm) | Comparison of sample color to APHA platinum-cobalt standards or measurement of absorbance at 430 nm in a 10-mm cell. |
| Density at 20 °C | Digital Density Meter (Oscillating U-tube principle) | Measurement of sample density via resonant frequency shift of a vibrating U-shaped tube filled with the sample. |
| Refractive Index at 20 °C | Digital Refractometer (Abbe principle) | Determination of refractive index by measuring the critical angle of total internal reflection at the prism-sample interface. |
| Heavy Metals (as Pb) | Inductively Coupled Plasma–Optical Emission Spectrometry (ICP-OES) | Quantification of trace metal impurities after microwave-assisted acid digestion, based on element-specific atomic emission lines. |
| Chloride Content | Ion Chromatography (IC) with Conductivity Detection | Separation of chloride anions on an anion-exchange column followed by quantitative detection via suppressed conductivity. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Weighing sample before and after controlled high-temperature ashing (550–600 °C) to determine non-volatile inorganic residue. |
| Viscosity at 25 °C | Rotational Viscometry (Spindle-type viscometer) | Measurement of dynamic viscosity based on torque required to rotate a spindle immersed in the sample at controlled temperature and shear rate. |
| pH (10% w/w aqueous solution) | Potentiometric pH Measurement | Determination of hydrogen ion activity using a calibrated glass electrode in a defined aqueous dilution. |
| Gas Impurities (e.g., NH₃, amines) | Headspace Gas Chromatography–Mass Spectrometry (HS-GC-MS) | Extraction of volatile impurities into headspace followed by separation and identification/quantification via mass spectral detection. |
| Residual Solvents (e.g., toluene, THF) | Gas Chromatography–Flame Ionization Detection (GC-FID) | Separation and quantification of low-boiling organic solvents using a suitable capillary column and FID response. |
| Appearance | Visual Inspection (in clear glass container under controlled lighting) | Assessment of clarity and presence of particulates or phase separation against specified criteria (e.g., “clear, colorless to pale yellow liquid”). |
