Manufacturing Quality Control of HEXADECANEDIOIC ACID
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Acid-Base Titration | Quantifies carboxylic acid groups via neutralization with standardized NaOH solution using phenolphthalein indicator. |
| Moisture Content | Karl Fischer Titration | Determines water content based on stoichiometric reaction between water, iodine, sulfur dioxide, and a base in methanol medium. |
| Melting Point | Capillary Melting Point Apparatus | Measures temperature range at which solid transitions to liquid, indicating purity and identity. |
| Color | APHA Color Scale (Visual or Spectrophotometric) | Compares sample color against platinum-cobalt standard solutions using visual assessment or spectrophotometer at 455 nm. |
| Acid Value | Acid-Base Titration | Determines milligrams of KOH required to neutralize free acids in 1 g of sample. |
| Iodine Value | Wijs Method | Measures unsaturation by reaction with excess iodine monochloride, followed by titration of unreacted iodine. |
| Residue on Ignition | Gravimetric Analysis | Quantifies inorganic ash content after high-temperature incineration and weighing of residual residue. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Detects trace metal impurities by measuring absorbance of ground-state atoms in flame or graphite furnace. |
| Sulfated Ash | Gravimetric Analysis | Measures non-volatile inorganic residue after ignition with sulfuric acid treatment. |
| Chloride Content | Potentiometric Titration (with AgNO3) | Determines chloride ions via titration with silver nitrate and silver-sulfide electrode detection. |
| Organic Impurities (Related Substances) | High-Performance Liquid Chromatography (HPLC) | Separates and quantifies structurally related compounds using reversed-phase C18 column and UV detection. |
| Particle Size Distribution | Laser Diffraction | Measures size distribution of solid particles in suspension by analyzing angular scattering pattern of laser beam. |
