Industrial Applications of ACID BLUE 161, PURE
| Industry | Application | Process |
|---|---|---|
| Textile Dyeing & Printing | Acid dyes for dyeing and printing protein fibers (e.g., wool, silk) and polyamide fibers (e.g., nylon) | Wet dyeing, typically conducted under mildly acidic conditions (pH 4–6), using either high-temperature (95–100°C) dyeing or ambient-temperature adsorption followed by fixation |
| Leather Industry | Chrome-complex dyes for leather coloring, providing excellent lightfastness and wet-fastness | Immersion dyeing at pH 3.5–5.0 and 30–40°C, followed by neutralization, rinsing, and drying |
| Paper Dyeing | Specialized acid dyes for coloring colored paper, decorative paper, and specialty paper | Surface sizing or internal addition; applied to near-neutral to mildly acidic pulp, with strict control of metal ion interference |
Manufacturing Quality Control of ACID BLUE 161, PURE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | UV-Vis Spectrophotometry | Quantitative determination based on absorbance at characteristic wavelength using molar absorptivity and Beer-Lambert law. |
| Moisture Content | Karl Fischer Titration | Electrochemical titration measuring water content via iodine-sulfur dioxide reaction in methanol-pyridine medium. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of trace metal impurities by measuring absorption of specific wavelengths of light by ground-state atoms in flame or graphite furnace. |
| Chromium Content | Redox Titration with Ammonium Cerium(IV) Sulfate | Oxidation of Cr(III) to Cr(VI) followed by back-titration with standardized ceric sulfate solution. |
| Sulfate Content | Gravimetric Analysis (Barium Sulfate Precipitation) | Precipitation of sulfate as BaSO4, followed by filtration, drying, and weighing of the insoluble residue. |
| pH of 1% Aqueous Solution | Potentiometric pH Measurement | Determination of hydrogen ion activity using calibrated glass electrode and pH meter in aqueous suspension. |
| Residue on Ignition | Gravimetric Analysis (Ignition at 550 C) | Measurement of non-volatile inorganic residue after high-temperature incineration and cooling in desiccator. |
| Chloride Impurity | Argentometric Titration (Mohr Method) | Titration with standard silver nitrate solution using potassium chromate indicator to detect endpoint by red Ag2CrO4 formation. |
| Organic Volatile Impurities | Gas Chromatography (GC-FID) | Separation and quantification of volatile organic solvents using capillary column and flame ionization detection. |
| Particle Size Distribution | Laser Diffraction Analysis | Measurement of scattered laser light intensity at multiple angles to determine size distribution of suspended particles. |
| Color Value (APHA) | Visual Comparison or Spectrophotometric Measurement | Comparison of sample solution color against APHA platinum-cobalt standards or measurement of yellowness index at 430 nm. |
| Water Insolubles | Filtration and Gravimetry | Filtration of aqueous solution through pre-weighed membrane filter, drying, and weighing of retained residue. |
