Manufacturing Quality Control of 1,1,4,4,6-Pentamethyl-1,2,3,4-tetrahydronaphthalene
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component by retention time and peak area relative to calibration standard. |
| Related Substances | Gas Chromatography-Mass Spectrometry (GC-MS) | Identifies and semi-quantifies impurities based on retention time and mass spectral fragmentation patterns. |
| Water Content | Karl Fischer Titration (Coulometric mode) | Measures water via electrochemical reaction between iodine, sulfur dioxide, and water in anhydrous methanol medium. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Determines non-volatile inorganic residue after controlled high-temperature ashing. |
| Acid Value | Acid-Base Titration (NaOH in ethanol) | Measures free acidic groups by titration with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Color | APHA Color Scale (Visual or Spectrophotometric) | Compares sample color intensity against platinum-cobalt standard solutions at 430 nm. |
| Density | Digital Density Meter (Oscillating U-tube principle) | Determines density from resonant frequency shift of a vibrating U-shaped tube filled with sample. |
| Refractive Index | Refractometry (Abbe refractometer) | Measures bending of light at air-sample interface to determine refractive index at specified temperature. |
| Non-Volatile Residue | Gravimetric Evaporation | Quantifies residue after evaporation of fixed sample volume under controlled heating and vacuum. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) with flame atomization | Measures absorbance of characteristic atomic line after nebulization and flame atomization of acid-digested sample. |
| Chloride Content | Potentiometric Titration (with AgNO3) | Detects endpoint via silver ion-selective electrode during titration with silver nitrate solution. |
| Flash Point | Pensky-Martens Closed Cup Tester | Determines lowest temperature at which vapors ignite momentarily when exposed to flame under standardized closed-cup conditions. |
