Industrial Applications of Solvent Orange 2
| Industry | Application | Process |
|---|---|---|
| Plastics Industry | Coloring plastics such as polystyrene and ABS | Added as a dye during plastic processing; uniform coloration achieved via mixing, melting, and molding |
| Ink Industry | Manufacturing orange inks for packaging printing and publications | Dispersed in ink vehicles and processed into inks through grinding and formulation; suitable for gravure and flexographic printing |
| Coatings Industry | Tinting industrial coatings and decorative paints | Mixed with resins and solvents, then processed into coatings via stirring and dispersion; applied for coloring metal and wood surfaces |
| Textile Industry | Dyeing synthetic fibers (e.g., polyester) | Applied using high-temperature, high-pressure dyeing or thermosol dyeing to affix dye onto fibers |
| Candle & Stationery Products | Coloring candles, colored pencils, and similar products | Directly incorporated into wax-based or oil-based materials; coloration achieved via heating, mixing, casting, or extrusion |
Manufacturing Quality Control of Solvent Orange 2
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reverse-phase HPLC with UV detection at characteristic wavelength (e.g., 430 nm) and external standard calibration. |
| Related Substances | HPLC-DAD | Separates and detects impurities using HPLC coupled with diode array detection for spectral confirmation and relative quantification. |
| Moisture Content | Karl Fischer Titration | Determines water content via coulometric or volumetric titration based on iodine generation and stoichiometric reaction with water. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing (550-600 C) and subsequent weighing. |
| Heavy Metals (as Pb) | ICP-OES | Quantifies total heavy metals by plasma excitation and elemental emission spectroscopy after acid digestion. |
| Chlorinated Impurities | GC-ECD | Detects chlorinated organic impurities using gas chromatography with electron capture detection for high sensitivity to halogens. |
| pH of Aqueous Suspension | Potentiometric Measurement | Measures hydrogen ion activity in a defined suspension (e.g., 1% w/v in water) using calibrated pH electrode. |
| Particle Size Distribution | Laser Diffraction | Determines size distribution by analyzing angular dependence of laser light scattering from dispersed particles in liquid medium. |
| Bulk Density | ASTM D1895 | Measures mass per unit volume of freely settled powder using standardized cylinder and tapping procedure. |
| Color Strength (Tinting Strength) | Visual Comparison or Reflectance Spectrophotometry | Evaluates dyeing performance relative to certified reference standard on specified substrate (e.g., cotton cloth) under controlled conditions. |
| Organic Volatile Impurities | Headspace GC-FID | Identifies and quantifies residual solvents using headspace sampling followed by gas chromatography with flame ionization detection. |
| Sulfated Ash | Gravimetric Analysis | Determines inorganic sulfate content after sulfuric acid treatment, ignition, and weighing of residual ash. |
