Industrial Applications of Solvent Red 49
| Industry | Application | Process |
|---|---|---|
| Plastics Industry | Coloration of thermoplastic resins including PS, ABS, and rigid PVC | Dissolved in the polymer matrix during compounding—via extrusion pelletizing or injection molding—to produce transparent coloration |
| Inks Industry | Metal surface printing inks, aluminum foil inks, and gravure inks for paper | Dissolved in organic solvents (e.g., aromatic hydrocarbons, esters) and milled with resin binders |
| Coatings Industry | Transparent metallic coatings, wood coatings, and bicycle finishes | Dissolved in coating systems such as alkyd or acrylic resins, then applied via spraying or brushing to yield transparent or metallic-finish coatings |
| Stationery & Educational Supplies | Ballpoint pen inks and marker inks | Used as a colorant dissolved in oil-based solvents to adjust ink viscosity |
| Cosmetics Industry | Coloration of nail polish and hair oils | Dissolved in nitrocellulose, resins, and solvent systems for nail polish formulations |
| Petroleum Industry | Color marking of gasoline, diesel, and lubricating oils | Directly dissolved in fuel or lubricant base oils for product identification or grade differentiation |
Manufacturing Quality Control of Solvent Red 49
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies Solvent Red 49 concentration using reversed-phase HPLC with UV detection at characteristic absorbance wavelength. |
| Color Strength | UV-Vis Spectrophotometry | Measures absorbance of standardized solution at lambda-max to determine relative dyeing power versus reference standard. |
| Moisture Content | Karl Fischer Titration | Determines water content via coulometric or volumetric titration with iodine-based reagent reacting stoichiometrically with water. |
| Ash Content | Gravimetric Analysis | Measures inorganic residue after high-temperature incineration and subsequent weighing of the ash. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-OES | Simultaneously quantifies trace metal impurities after acid digestion by measuring element-specific atomic emission intensities. |
| Chlorinated Impurities | GC-MS | Identifies and quantifies chlorinated aromatic by-products using gas chromatography separation coupled with mass spectrometric detection. |
| pH of Aqueous Suspension | pH Meter Measurement | Determines acidity/alkalinity of a defined suspension in distilled water using calibrated pH electrode. |
| Particle Size Distribution | Laser Diffraction | Analyzes size distribution of dispersed particles in liquid medium based on angular dependence of scattered laser light. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile residue after heating sample at specified temperature (e.g., 500 C) for fixed duration. |
| Organic Volatile Impurities | Headspace GC-FID | Detects residual solvents (e.g., toluene, xylene) via headspace sampling followed by gas chromatography with flame ionization detection. |
| Sulfated Ash | Gravimetric Analysis | Quantifies ash content after treatment with sulfuric acid prior to ignition, indicating sulfate-forming impurities. |
| Substance Loss on Drying | Thermogravimetry | Measures mass loss upon heating under controlled conditions (e.g., 105 C, 2 h) to assess volatile and moisture content. |
