Industrial Applications of 3,4,5,6-Tetrachlorophthalonitrile
| Industry | Application | Process |
|---|---|---|
| Agrochemicals | Active ingredient for fungicides | Serves as a key intermediate in the synthesis of chlorothalonil via hydrolysis, acid chloride formation, and amination. |
| Agrochemicals | Agrochemical intermediate | Used to synthesize other biologically active tetrachlorobenzene derivatives or heterocyclic compounds. |
| Dye industry | Pigment intermediate | Converted chemically into high-performance organic pigments (e.g., phthalocyanine pigments) for colorant production. |
| Organic synthesis | Synthesis of specialty chemicals | Leverages its reactive cyano and chloro groups in nucleophilic substitution reactions to construct complex organic molecular frameworks. |
Manufacturing Quality Control of 3,4,5,6-Tetrachlorophthalonitrile
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantitative determination based on peak area comparison against a certified reference standard under optimized chromatographic conditions. |
| Related Substances | Gas Chromatography (GC) with FID or Mass Spectrometry (GC-MS) | Separation and identification of impurities by retention time and/or mass spectral matching; quantification relative to main peak. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Volatile solvents are vaporized in sealed vials, then injected and separated on a capillary column for quantification. |
| Water Content | Karl Fischer Titration (Coulometric mode) | Electrochemical titration where iodine is generated in situ to react stoichiometrically with water; endpoint detected amperometrically. |
| Heavy Metals (as Pb) | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Sample digested in acid matrix, then atomized and excited in plasma; metal concentrations determined from element-specific emission intensities. |
| Chloride Ion Impurity | Ion Chromatography (IC) with conductivity detection | Anions separated on an ion-exchange column and quantified by changes in electrical conductivity of the eluent stream. |
| Ash Content | Gravimetric Analysis (Ignition at 550 C) | Sample incinerated to constant weight; residual inorganic residue weighed after cooling in desiccator. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed visually or automatically as the temperature at which solid phase completely converts to liquid. |
| Appearance | Visual Inspection (against white/black background) | Assessment of physical state, color, and presence of visible particulates or discoloration under controlled lighting. |
| Particle Size Distribution | Laser Diffraction Particle Size Analysis | Scattering pattern of laser beam passing through dispersed sample is analyzed to calculate size distribution based on Mie theory. |
| Bulk Density | ASTM D1895 Method A (Tapped Density) | Mass per unit volume measured after standardized tapping of a graduated cylinder containing the powder. |
| Organic Volatile Impurities (non-solvent) | Gas Chromatography-Mass Spectrometry (GC-MS) | Non-targeted screening and semi-quantitative detection of low-level volatile organic impurities using full-scan MS detection. |
