Industrial Applications of 1,4-Diamino anthraquinone
| Industry | Application | Process |
|---|---|---|
| Dye Industry | Used as an intermediate in the synthesis of anthraquinone dyes, particularly for producing blue and green disperse dyes and vat dyes | Further converted into target dye molecules via chemical reactions such as acylation, sulfonation, or halogenation |
| Textile Printing & Dyeing | Applied as a dyeing auxiliary or directly used for dyeing synthetic fibers such as polyester and acetate | High-temperature, high-pressure dyeing or thermosol dyeing process |
| Ink Manufacturing | Employed in the production of high-performance organic pigments, imparting vivid color and excellent lightfastness to inks | After pigmentization (e.g., acid dissolution–reprecipitation), blended with resins and solvents for ink formulation |
| Plastic Coloring | Serves as a precursor compound for blue or green colorants used in plastics | Compounded with carrier resin and pelletized for coloring applications in injection molding or extrusion processes |
| Research | Utilized in studying the optoelectronic properties of anthraquinone compounds and as a precursor for fluorescent probe materials | Chemically modified for spectroscopic analysis or device fabrication experiments |
Manufacturing Quality Control of 1,4-Diamino anthraquinone
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reversed-phase HPLC with UV detection at 520 nm, comparing peak area against a certified reference standard. |
| Moisture Content | Karl Fischer Titration | Electrochemical titration measuring water content based on the stoichiometric reaction of iodine with water in a methanol-based reagent. |
| Ash Content | Gravimetric Analysis | Incineration at 550-600 C followed by weighing of residual inorganic material after complete organic matter removal. |
| Residue on Ignition | Gravimetric Analysis | Weight loss measurement after heating at 700 C for 30 min; residue mass expressed as percentage of original sample. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of total heavy metals after acid digestion, using air-acetylene flame AAS at characteristic wavelengths. |
| Chloride Impurity | Ion Chromatography (IC) | Separation and quantification of chloride ions on an anion-exchange column with suppressed conductivity detection. |
| Sulfate Impurity | Barium Sulfate Gravimetry | Precipitation of sulfate as BaSO4 in acidic medium, followed by filtration, drying, and weighing. |
| Iron Content | ICP-OES | Multi-element quantification after microwave-assisted acid digestion using inductively coupled plasma optical emission spectrometry. |
| Particle Size Distribution | Laser Diffraction | Measurement of scattered laser light intensity to determine volume-based particle size distribution in dispersed suspension. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed visually or optically as the temperature range at which solid phase converts to liquid. |
| Organic Volatile Impurities | Gas Chromatography (GC-FID) | Separation and detection of volatile organic impurities using capillary GC with flame ionization detection. |
| Color Value (APHA) | UV-Vis Spectrophotometry | Measurement of absorbance at 430 nm in a 5% w/v solution in concentrated sulfuric acid, compared to APHA platinum-cobalt standards. |
