Manufacturing Quality Control of 1,16-HEXADECANEDIOL
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies 1,16-hexadecanediol peak area relative to internal standard or calibration curve. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between iodine, sulfur dioxide, and water in methanol/pyridine medium. |
| Acid Value | Acid-Base Titration with NaOH | Determines free carboxylic acid impurities by titration with standardized sodium hydroxide solution. |
| Hydroxyl Value | Acetylation followed by Titration | Measures total hydroxyl groups by acetylating with acetic anhydride, then back-titrating excess reagent. |
| Color (APHA) | Visual Comparison or Spectrophotometry at 455 nm | Evaluates yellowness intensity by comparing sample color to APHA platinum-cobalt standards. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using calibrated capillary tube method. |
| Residue on Ignition | Gravimetric Analysis after High-Temperature Ashing | Measures non-volatile inorganic residue remaining after combustion at 700-800 C. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals by atomization and absorption measurement at characteristic wavelengths. |
| Chloride Content | Ion Chromatography (IC) or Potentiometric Titration | Separates and detects chloride ions via conductivity detection or silver nitrate titration with endpoint detection. |
| Sulfated Ash | Gravimetric Analysis after Sulfuric Acid Treatment | Measures ash content after sulfuric acid digestion and high-temperature incineration. |
| Appearance | Visual Inspection | Assesses physical state, clarity, and presence of particulates or discoloration under controlled lighting. |
| Bulk Density | Graduated Cylinder Method (ASTM D1895) | Determines mass per unit volume by measuring weight of material freely poured into a calibrated cylinder. |
