Industrial Applications of NAPHTHOL AS-MX
| Industry | Application | Process |
|---|---|---|
| Dye Manufacturing | Coupling component for preparing azoic dyes (naphthols) | Primarily used in manufacturing red azoic dyes, such as C.I. Azoic Coupling Component 3 and C.I. Azoic Coupling Component 31; coupled with diazotized bases on fiber substrates to develop color |
| Textile Printing & Dyeing | Dyeing of cotton, linen, viscose, and other cellulosic fibers | Azoic dyeing process (ice dyeing): fabric impregnated with naphthol AS-MX, followed by coupling with a diazo salt developer to produce color |
| Organic Pigment Synthesis | Production of high-performance organic pigments (e.g., Pigment Red 149) | Chemical synthesis and derivatization of naphthol AS-MX to yield pigments for coating and ink applications |
| Printing Ink Manufacturing | Colorant for inks | Organic pigments derived from naphthol AS-MX are dispersed into ink vehicles via dispersion processing |
| Coating Manufacturing | Pigmentation of industrial coatings | Organic pigments derived from naphthol AS-MX are incorporated into coating formulations via grinding and dispersion processing |
Manufacturing Quality Control of NAPHTHOL AS-MX
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reverse-phase chromatography with UV detection at 254 nm based on peak area comparison against reference standard. |
| Moisture Content | Karl Fischer Titration | Determines water content by coulometric or volumetric titration using iodine generation in pyridine-methanol solvent system. |
| Ash Content | Gravimetric Analysis | Measures inorganic residue after complete combustion at 550-600 C and subsequent weighing of cooled residue. |
| Chloride Impurity | Potentiometric Titration | Quantifies chloride ions using silver nitrate titrant with silver indicator electrode and reference electrode. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Measures total heavy metal content by atomization in flame and absorption of characteristic wavelength light. |
| Sulfated Ash | Gravimetric Analysis | Determines residual inorganic sulfate after ignition with sulfuric acid pretreatment and high-temperature ashing. |
| pH of Aqueous Slurry | pH Meter Measurement | Measures hydrogen ion activity in 10% w/v suspension in distilled water using calibrated glass electrode. |
| Organic Impurities (Related Substances) | HPLC-DAD | Identifies and quantifies structurally related compounds using HPLC separation with diode array detection for spectral confirmation. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using capillary tube and controlled heating rate. |
| Bulk Density | Graduated Cylinder Method | Calculates mass per unit volume by gently pouring sample into calibrated cylinder and measuring settled volume. |
| Particle Size Distribution | Laser Diffraction | Measures size distribution by analyzing angular variation in laser light scattering from dispersed particles in air or liquid. |
| Residue on Ignition | Gravimetric Analysis | Determines non-volatile residue after heating at 700-750 C for specified time and weighing cooled crucible. |
