Industrial Applications of 135-63-7
| Industry | Application | Process |
|---|---|---|
| Dyes and Textile Printing & Dyeing | Coupling component (developing agent) for azoic dyes (naphthol dyes) | Primarily used for dyeing and printing cotton, viscose, and certain synthetic fibers; typical process includes: dissolving Color Phenol AS-KB in sodium hydroxide solution to prepare the developing bath → padding fabric with the developing bath → drying → coupling with a diazonium salt (color base) solution for color development → after-treatment (soaping and rinsing). |
| Dyes and Textile Printing & Dyeing | Intermediate for producing temporary-soluble dyes such as Fast Color Salt, Fast Acid Salt, and Fast Sulphur Salt | Reacted as a coupling component with diazonium salts (or their derivatives) to form stable complex dyes; during printing or dyeing, the active dye component is released upon acidic treatment or steaming and develops color directly on the fabric. |
| Pigments | Raw material for organic pigment synthesis | Used in the synthesis of azo pigments; coupled via diazotization-coupling reactions with specific aromatic amine diazonium salts to produce insoluble azo pigment lakes, widely applied in inks, paints, coatings, and plastic coloration. |
Manufacturing Quality Control of 135-63-7
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification based on peak area comparison against certified reference standard using reversed-phase chromatography and UV detection at 254 nm. |
| Moisture Content | Karl Fischer Titration | Electrochemical titration measuring water content via iodine-sulfur dioxide reaction in methanol-based solvent. |
| Ash Content | Gravimetric Analysis | Residue mass after incineration at 550-600 C, expressed as percentage of original sample weight. |
| Chloride Impurity | Ion Chromatography (IC) | Separation and quantification of chloride ions using anion-exchange column with conductivity detection. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-OES | Multi-element detection by measuring atomic emission intensities of plasma-excited metal ions. |
| pH of Aqueous Suspension | Potentiometric Measurement | Determination of hydrogen ion activity using calibrated pH electrode in 1% w/v aqueous suspension. |
| Organic Volatile Impurities | GC-FID | Separation and quantification of residual solvents using capillary gas chromatography with flame ionization detection. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered light intensity patterns to calculate volume-based particle size distribution. |
| Bulk Density | Gravimetric Volumetric Method | Mass of material per unit volume measured in standardized cylinder under controlled tapping conditions. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed as temperature range where solid phase converts to liquid under controlled heating rate. |
| Sulfate Content | Gravimetric Sulfate Precipitation | Precipitation as BaSO4 followed by filtration, drying, and weighing of the insoluble residue. |
| Residue on Ignition | Gravimetric Method | Mass loss upon heating at 700-750 C; reported as non-volatile inorganic residue percentage. |
