Industrial Applications of Chlorthal
| Industry | Application | Process |
|---|---|---|
| Chemical Intermediates | Synthesis of polyester resins, dyes, and pharmaceutical intermediates | Prepared via esterification with alcohols or amidation with amines using terephthaloyl chloride |
| Fine Chemicals | Production of high-performance polymer materials (e.g., liquid crystal polymers) | Used as a monomer in condensation polymerization to form polymeric chain structures |
| Pharmaceutical R&D | Synthesis of precursors to active pharmaceutical ingredients (APIs) | Employed to construct aromatic ring systems, with functional groups introduced via reduction or substitution reactions |
| Polymer Materials | Manufacture of high-temperature-resistant engineering plastics and fibers | Copolymerized with difunctional monomers to enhance thermal stability and mechanical properties |
| Dye Industry | Key intermediate in dye synthesis | Undergoes coupling or condensation reactions with aromatic amines to produce azo or phthalocyanine dyes |
Manufacturing Quality Control of Chlorthal
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reversed-phase HPLC with UV detection at 220-230 nm, based on peak area comparison against certified reference standard. |
| Moisture Content | Karl Fischer Titration | Electrochemical titration using iodine generated in situ to react stoichiometrically with water in the sample. |
| Residue on Ignition | Gravimetric Analysis | Heating sample at 750-800 C to constant weight and measuring non-volatile inorganic residue as mass percent. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element quantification of trace metals after acid digestion, using plasma-excited atomic emission spectroscopy. |
| Chloride Impurity | Potentiometric Titration | Titration with silver nitrate using silver indicator electrode; endpoint detected by potential jump due to AgCl precipitation. |
| Related Substances | HPLC-DAD | Separation and identification of structurally similar impurities (e.g., mono-, di-, tri-chloro isomers) using diode-array detection. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid transitions to liquid, following USP <741> or ISO 6391. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity to calculate volume-based particle size distribution in dry or wet dispersion. |
| pH of Aqueous Suspension | pH Meter | Measurement of hydrogen ion activity in a defined suspension (e.g., 1% w/v in water) using calibrated glass electrode. |
| Sulfated Ash | Gravimetric Analysis | Sample charred, treated with sulfuric acid, then ignited at 700-750 C; residue weighed as sulfate ash content. |
| Organic Volatile Impurities | GC-FID | Headspace or direct injection GC with flame ionization detection for residual solvents (e.g., chlorobenzene, DMF). |
| Bulk Density | Tap Density Tester | Measurement of mass per unit volume after controlled tapping of a known mass in a graduated cylinder per ASTM D1895. |
