Industrial Applications of Solvent Red 41
| Industry | Application | Process |
|---|---|---|
| Printing Inks | Colorant additive to enhance ink color strength and stability | Dissolved in organic solvent during ink formulation, then incorporated into the ink base |
| Plastic Coloring | Colorant for plastic products, imparting a red hue | Pre-mixed uniformly with resin prior to plastic processing (e.g., injection molding, extrusion) |
| Coatings Industry | Provides vivid red coloration in coatings | Dispersed into the resin system and processed into coatings via grinding and formulation |
| Chemical Reagents | Used in laboratory analysis or as a dye reference standard | Employed as a reference dye in colorimetric or spectroscopic analysis |
| Textile Dyeing and Printing | Applied for dyeing or printing certain specialty fibers | Dyeing performed under specific conditions (e.g., acidic medium) |
Manufacturing Quality Control of Solvent Red 41
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies Solvent Red 41 peak area against a certified reference standard using reversed-phase chromatography and UV detection at ~520 nm. |
| Color Strength | UV-Vis Spectrophotometry | Measures absorbance of standardized solution at lambda-max; correlates to dyeing power relative to reference standard. |
| Loss on Drying | Gravimetric (Oven Drying) | Determines volatile content by measuring mass loss after drying at 105 C for 2 hours under controlled humidity conditions. |
| Ash Content | Gravimetric (Muffle Furnace) | Measures inorganic residue remaining after combustion at 550 C for 30 minutes. |
| Heavy Metals (as Pb) | AAS or ICP-OES | Quantifies total heavy metals by atomic absorption or optical emission after acid digestion and matrix-matched calibration. |
| Chlorinated Benzene Impurities | GC-MS | Identifies and quantifies residual chlorobenzene solvents using capillary gas chromatography coupled with mass spectrometric detection. |
| pH of Aqueous Extract | Potentiometric Titration | Measures hydrogen ion activity in aqueous suspension using calibrated pH electrode under standardized dispersion conditions. |
| Particle Size Distribution | Laser Diffraction | Determines size distribution of dispersed particles in liquid medium via angular scattering pattern analysis. |
| Water Solubility | Visual Inspection & Filtration | Evaluates clarity and presence of undissolved residue after agitation and filtration of saturated aqueous solution at 25 C. |
| Residual Solvents (e.g., Toluene, Xylene) | GC-FID | Quantifies volatile organic residues using gas chromatography with flame ionization detection and internal standard calibration. |
| Sublimation Loss | Thermogravimetric Analysis (TGA) | Measures mass loss under nitrogen atmosphere from 25 C to 300 C at 10 C/min to assess thermal volatility. |
| Bulk Density | ASTM D1895 Method A | Determines mass per unit volume of freely settled powder using standardized graduated cylinder and tapping procedure. |
