Industrial Applications of Solvent Red 146
| Industry | Application | Processing |
|---|---|---|
| Coatings & Inks | Red colorant for solvent-based coatings and printing inks (e.g., gravure, flexographic inks) | Dissolved directly in organic solvents (e.g., toluene, ethyl acetate, acetone) to formulate color pastes or concentrates, then added to the base system at the required ratio |
| Plastics | Colorant for thermoplastic resins including polyolefins (PP, PE), PVC, and PS | Added as masterbatch or dry powder during melt processing of plastics (e.g., extrusion, injection molding) for uniform dispersion in the polymer matrix |
| Textiles | Mass-coloration and exhaust dyeing of synthetic fibers such as polyester and nylon | Applied in high-temperature, high-pressure dyeing processes (~130°C) or used as a spinning dope additive, leveraging its excellent sublimation fastness and thermal stability |
| Cosmetics | Colorant for external-use products only (e.g., lipsticks, nail enamels) | Incorporated into formulations at concentrations compliant with the “Technical Specifications for Cosmetic Safety” (typically ≤0.5%), dissolved in volatile solvents or oils, and homogenized via emulsification |
Manufacturing Quality Control of Solvent Red 146
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reverse-phase HPLC with UV detection at characteristic wavelength. |
| Related Substances | HPLC-DAD | Detects and quantifies structurally similar impurities via diode array detection. |
| Moisture Content | Karl Fischer Titration | Measures water content by coulometric or volumetric titration with iodine-based reagent. |
| Residue on Ignition | Gravimetric Analysis | Determines inorganic ash content after high-temperature incineration and weighing. |
| Heavy Metals | ICP-OES | Quantifies trace metals (e.g., Pb, Cd, Hg) by plasma excitation and optical emission detection. |
| Chlorinated Impurities | GC-ECD | Detects chlorinated organic residues using gas chromatography with electron capture detection. |
| pH of Aqueous Suspension | Potentiometric Measurement | Measures hydrogen ion activity in 1% w/v aqueous suspension using calibrated pH electrode. |
| Particle Size Distribution | Laser Diffraction | Determines size distribution based on angular scattering pattern of laser light through dispersed sample. |
| Bulk Density | USP <616> Tap Density Test | Calculates mass per unit volume after controlled mechanical tapping of powder in graduated cylinder. |
| Sulphated Ash | Gravimetric Analysis | Measures non-volatile inorganic residue after ignition with sulphuric acid pretreatment. |
| Solvent Residues | GC-FID | Quantifies residual manufacturing solvents (e.g., toluene, DMF) using flame ionization detection. |
| Color Strength (Relative) | UV-Vis Spectrophotometry | Compares absorbance ratio of sample solution to certified reference standard at lambda-max. |
