Manufacturing Quality Control of 1,4-cyclohexanedicarboxylicacid,diethylester
| 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 coulometric or volumetric titration based on iodine consumption in pyridine-methanol solvent. |
| Acid Value | Acid-Base Titration with NaOH | Determines free acid content by titrating with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement | Compares sample color to APHA platinum-cobalt standard solutions or measures absorbance at 430 nm. |
| Density at 20 C | Digital Density Meter | Measures mass per unit volume using oscillating U-tube principle calibrated with air and water. |
| Refractive Index at 20 C | Refractometry | Determines ratio of light velocity in air vs. sample using critical angle measurement with sodium D-line light. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing and cooling in desiccator. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals after wet digestion by measuring atomic absorption of ground-state metal atoms in flame. |
| Chloride Content | Potentiometric Titration with AgNO3 | Detects chloride ions by titration with silver nitrate using silver electrode for endpoint detection. |
| Volatility Residue | Thermogravimetric Analysis (TGA) | Measures mass loss under controlled heating to determine volatile impurities up to 250 C. |
| Appearance | Visual Inspection | Assesses physical state, clarity, and presence of particulates or phase separation against specified criteria. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light caused by chiral molecules in solution using sodium D-line. |
