Industrial Applications of Fluorescent Brightener 113
| Industry | Application | Process |
|---|---|---|
| Textile Industry | Enhances whiteness and brightness of fiber-based products; used in whitening treatments for cotton, polyester, nylon, and other fabrics | Added during dyeing or finishing processes; fluorescent whitening agent 113 is activated by UV light to emit blue light, compensating for yellowish tones and improving visual whiteness |
| Paper Industry | Used for paper whitening to improve whiteness and gloss | Added during pulp sheet formation, ensuring uniform mixing with fibers to enhance optical properties |
| Plastics Industry | Functions as a plastic additive to improve whiteness and gloss of polyolefin, polystyrene, and other plastic products | Incorporated during melt processing to prevent yellowing and improve aesthetic appearance |
| Detergent Industry | Used in laundry powders and liquid detergents to enhance post-wash whiteness and brightness of textiles | Formulated into detergent compositions to render laundered fabrics brighter white under UV illumination |
| Inks and Coatings | Applied in printing inks and coating systems to improve whiteness and visual performance | Added as an auxiliary component to ink or coating base formulations to enhance opacity and gloss |
Manufacturing Quality Control of Fluorescent Brightener 113
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination based on peak area comparison with a certified reference standard using reversed-phase chromatography and UV detection at 345 nm. |
| Moisture Content | Karl Fischer Titration | Electrochemical titration measuring water content via reaction of iodine with sulfur dioxide in a methanol-based solvent system. |
| Ash Content | Gravimetric Analysis | Residue mass after incineration at 550-600 C, expressed as percentage of original sample weight. |
| pH of Aqueous Solution | Potentiometric Measurement | Hydrogen ion activity measured using calibrated glass electrode in a 1 g/L aqueous dispersion. |
| Heavy Metals (as Pb) | AAS (Flame or Graphite Furnace) | Atomic absorption spectroscopy quantifying lead concentration after acid digestion and matrix-matched calibration. |
| Sulfated Ash | Gravimetric Analysis | Residue mass after incineration in presence of sulfuric acid to convert metals to sulfates, followed by weighing. |
| Organic Impurities (Related Substances) | HPLC-DAD | Separation and detection of structurally related compounds using gradient HPLC and diode-array detection for spectral confirmation. |
| Solvent Residues (e.g., DMF, Methanol) | GC-FID | Quantification of residual solvents by gas chromatography with flame ionization detection using internal standard calibration. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity versus angle to determine volume-based particle size distribution in aqueous suspension. |
| Color Value (Yellowness Index) | CIE Tristimulus Colorimetry | Measurement of reflected light in CIELAB color space using standardized illuminant D65 and 10-degree observer. |
| Bulk Density | Tap Density Measurement | Mass per unit volume determined by tapping a known mass of powder in a graduated cylinder until constant volume is achieved. |
| Water Solubility | Visual Dissolution Test | Qualitative assessment of complete dissolution in distilled water at 25 C with gentle agitation over 30 minutes. |
