Industrial Applications of N,N-DIETHYL-P-PHENYLENEDIAMINE SULFATE
| Industry | Application | Process |
|---|---|---|
| Analytical Chemistry | Colorimetric reagent for determining free chlorine, total chlorine, and residual chlorine in water quality testing | Reacts with chlorine to form a pink-to-purple azo dye, enabling quantitative analysis by colorimetry |
| Environmental Monitoring | On-site rapid detection of chlorine concentration in drinking water, wastewater, and swimming pool water | Based on the DPD (N,N-diethyl-p-phenylenediamine) method, in accordance with standard methods such as ISO 7393-2 and APHA 4500-Cl G |
| Industrial Water Treatment | Online or portable monitoring of oxidizing biocide (e.g., sodium hypochlorite) dosage in recirculating cooling water and boiler feedwater systems | Undergoes specific oxidative color-forming reactions with chlorine or chloramines, supporting automated sensor or test strip development |
Manufacturing Quality Control of N,N-DIETHYL-P-PHENYLENEDIAMINE SULFATE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Acid-Base Titration with Standardized HCl | Quantifies the primary amine content by protonation of the diethylamino groups in acidic medium, using methyl orange or bromocresol green as indicator. |
| Heavy Metals (as Pb) | Colorimetric Test (Thiourea/Lead Acetate) | Compares sample solution color intensity after reaction with thiourea under acidic conditions against lead standard solutions. |
| Sulfate Content | Gravimetric Analysis (Barium Sulfate Precipitation) | Precipitates sulfate as BaSO₄ under controlled pH and temperature; mass determined after ignition and drying. |
| Water Content | Karl Fischer Titration | Electrochemical titration quantifying water via iodine–sulfur dioxide reaction in methanol–pyridine solvent system. |
| Related Substances (Impurities) | HPLC-UV | Separates and quantifies structurally related impurities (e.g., monoethyl derivative, oxidation products) using reversed-phase C18 column and UV detection at 254 nm. |
| Residue on Ignition | Gravimetric (Ignition at 700–800 °C) | Measures non-volatile inorganic residue after charring and high-temperature incineration. |
| pH (1% aqueous solution) | Potentiometric pH Measurement | Determines hydrogen ion activity in a defined aqueous solution using calibrated glass electrode. |
| Appearance and Color | Visual Inspection Against Standard Solutions (e.g., APHA/Hazen) | Assesses clarity and yellowish tint by comparison to platinum-cobalt reference standards under controlled lighting. |
| Iron (Fe) | ICP-OES | Quantifies trace iron by measuring characteristic atomic emission lines after acid digestion and plasma excitation. |
| Chloride (Cl⁻) | Argentometric Titration (Mohr Method) | Titrates chloride with standardized silver nitrate in neutral medium, detecting endpoint via brick-red Ag₂CrO₄ precipitate. |
| Loss on Drying | Thermogravimetric Analysis (TGA) or Oven Drying at 105 °C | Measures mass loss after drying under specified temperature and time to determine volatile content including residual solvents/moisture. |
| Microbial Contamination | Membrane Filtration & Plate Count | Detects aerobic microorganisms by filtration, membrane transfer to nutrient agar, and colony enumeration after incubation. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light induced by chiral centers in solution using sodium D-line (589 nm). |
