Manufacturing Quality Control of ISOPROPYL P-TOLUENESULFONATE
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the sample's color and physical state (e.g., colorless to pale yellow transparent liquid), as well as the presence of any suspended particles or precipitates. |
| Purity | Gas Chromatography (GC) | Separation using a capillary column with FID detection; main component purity is calculated by area normalization or external standard method. |
| Water Content | Karl Fischer Titration | Utilizes the reaction between iodine and sulfur dioxide in a pyridine/methanol system with water; endpoint is determined by potentiometric or visual indication, enabling quantification of trace moisture. |
| p-Toluenesulfonic Acid Residue | High-Performance Liquid Chromatography (HPLC) | Reverse-phase chromatographic column with UV detection (e.g., 220 nm); residue levels of p-toluenesulfonic acid are quantified using the external standard method. |
| Isopropanol Residue | Gas Chromatography (GC) | Headspace or direct injection; qualitative identification by retention time and quantitative determination by peak area for residual solvent isopropanol. |
| pH Value (in aqueous solution) | pH Meter Measurement | Dissolve the sample in appropriate water, then measure acidity/alkalinity using a calibrated pH meter to assess the level of acidic impurities. |
| Density | Density Meter Method / Specific Gravity Bottle Method | Measure sample density at a specified temperature (e.g., 20°C) using digital densitometer or specific gravity bottle. |
| Refractive Index | Abbe Refractometer | Determine refractive index at standard temperature (e.g., 20°C), used for auxiliary identification and purity assessment. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) | After sample digestion, heavy metals such as lead, arsenic, and mercury are quantified using atomic absorption spectrometry. |
| Residue on Ignition | Gravimetric Method | Sample is subjected to high-temperature incineration followed by weighing of the residual ash to evaluate inorganic impurity content. |
