Manufacturing Quality Control of 1,3-DIPHENYLPROPANE
| 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 non-polar capillary column. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration where iodine generated in situ reacts stoichiometrically with water; endpoint detected amperometrically. |
| Residue on Ignition | Gravimetric Analysis | Measurement of non-volatile inorganic residue after high-temperature ashing at 700-800 C in a muffle furnace. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of total heavy metals after acid digestion by measuring absorbance of ground-state atoms at characteristic wavelengths. |
| Chloride Impurity | Ion Chromatography (IC) | Separation and quantification of chloride anions using an anion-exchange column and suppressed conductivity detection. |
| Acid Value | Acid-Base Titration (NaOH in ethanol) | Neutralization of acidic impurities with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement | Comparison of sample color to platinum-cobalt standard solutions or measurement of absorbance at 455 nm in a 10-mm cell. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range over which solid transitions to liquid, observed visually under controlled heating rate. |
| Specific Optical Rotation | Polarimetry | Measurement of angular rotation of plane-polarized light caused by chiral impurities or enantiomeric excess in solution. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Extraction and quantification of volatile organic solvents via equilibrium headspace sampling followed by GC-FID analysis. |
| Non-Volatile Residue | Evaporation and Gravimetry | Weighing of residue remaining after evaporation of a known volume under controlled temperature and airflow conditions. |
| Appearance (Clarity and Color) | Visual Inspection in Nessler Tube | Subjective assessment of clarity (haze, particulates) and color against water or specified standards under standardized lighting. |
