| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Purity/Content Determination | Gas Chromatography (GC) | Using a gas chromatograph equipped with a capillary column of suitable polarity (e.g., DB-5, HP-5) to separate o-chlorophenyl isocyanate, followed by quantitative analysis via Flame Ionization Detector (FID) or Mass Spectrometry (MS). The main component content is calculated using internal or external standard methods to evaluate product purity. |
| Isocyanate Group (–NCO) Content | Titration Method (Dibutylamine Method) | The isocyanate group reacts with excess dibutylamine to form urea; the unreacted dibutylamine is back-titrated with standardized hydrochloric acid solution. The –NCO group content is calculated based on the amount of HCl consumed, reflecting the concentration of active functional groups. |
| Moisture Content | Karl Fischer Titration | Using volumetric or coulometric Karl Fischer moisture analyzer, where iodine and sulfur dioxide react quantitatively with water in the presence of pyridine/imidazole, enabling precise measurement of trace moisture. This prevents hydrolysis of isocyanate groups caused by water. |
| Color | Visual Color Comparison or Platinum-Cobalt (Pt-Co) Color Scale | The sample is placed in a colorimeter tube and compared visually with standard platinum-cobalt solutions, or its APHA/Hazen color value is measured using a colorimeter to assess appearance and degree of oxidation or impurities. |
| Acidity (as HCl) | Acid-Base Titration | The sample is dissolved in anhydrous ethanol or acetone, and free acids (mainly HCl from hydrolysis) are titrated with standardized sodium hydroxide solution using phenolphthalein as indicator. The acid value is calculated to monitor side reactions such as hydrolysis. |
| Volatile Impurities | Gas Chromatography-Mass Spectrometry (GC-MS) | GC-MS is used to qualitatively and semi-quantitatively analyze low-boiling-point or volatile organic impurities (e.g., o-chloroaniline, chlorobenzene, residual solvents), ensuring impurity levels meet quality specifications. |
| Density | Densitometer or Pycnometer Method | Density is measured at a specified temperature (typically 20°C or 25°C) using a digital densitometer or pycnometer, serving as an auxiliary quality control parameter. |
| Refractive Index | Abbe Refractometer Method | The refractive index of the sample is measured using an Abbe refractometer at standard temperature, useful for rapid identification and supplementary purity assessment. |
