Industrial Applications of 130-20-1
| Industry | Application | Process |
|---|---|---|
| Textile Dyeing and Printing | Dyeing and printing of cotton, linen, and viscose fibers | Reduction dyeing: Sodium hydrosulfite (sodium dithionite) and sodium hydroxide are used under alkaline conditions to reduce the dye to its soluble leuco form; fabrics are then immersed or padded in the dye bath, followed by air oxidation to develop color. For printing, the leuco form is mixed with a printing paste and auxiliaries, applied to the fabric, and then steamed to oxidize and fix the dye. |
| Leather Industry | Leather coloring | Immersion dyeing: Leather is treated in a dye bath containing the leuco form of Indanthrene Blue 6, with pH and temperature carefully controlled; color is developed through subsequent oxidation. |
| Paper Industry | Paper coloring (e.g., specialty art papers, banknote papers) | Added to the paper pulp suspension prior to sheet formation; dye fixation onto fibers occurs via a reduction-oxidation mechanism. |
Manufacturing Quality Control of 130-20-1
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | UV-Vis Spectrophotometry | Quantifies main component concentration via absorbance at characteristic wavelength using Beer-Lambert law. |
| Moisture Content | Karl Fischer Titration | Determines water content by coulometric or volumetric titration with iodine-based reagent. |
| Ash Content | Gravimetric Analysis | Measures inorganic residue after high-temperature incineration and weighing. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies lead and other heavy metals by atomic absorption of specific wavelengths in atomized sample. |
| Chloride Content | Potentiometric Titration with AgNO3 | Measures chloride ions via precipitation titration monitored by silver ion-selective electrode. |
| Sulfate Content | Gravimetric Analysis (as BaSO4) | Determines sulfate by precipitation as barium sulfate followed by filtration and weighing. |
| pH of Aqueous Solution | pH Meter Measurement | Measures hydrogen ion activity in 1% aqueous suspension using calibrated glass electrode. |
| Solubility in Water | Visual Observation and Filtration | Evaluates complete dissolution behavior in specified volume of water at defined temperature. |
| Organic Impurities (Related Substances) | HPLC-UV | Separates and quantifies structurally related impurities using reversed-phase chromatography and UV detection. |
| Particle Size Distribution | Laser Diffraction | Analyzes size distribution by measuring angular variation in laser light scattering pattern. |
| Bulk Density | Graduated Cylinder Method | Determines mass per unit volume of freely settled powder in standardized cylinder. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile residue remaining after ignition at specified temperature, expressed as percentage. |
