Industrial Applications of 151841-65-5
| Industry | Application | Process |
|---|---|---|
| Plastics Industry | Heat stabilizer and antioxidant for polyolefins (e.g., PP, PE) | Added synergistically with primary antioxidants (e.g., hindered phenols) during late-stage polymerization or pelletizing to chelate catalytic metal ions and scavenge free radicals, thereby inhibiting oxidative degradation during high-temperature processing |
| Synthetic Rubber | Processing stabilizer for styrene-butadiene rubber (SBR), polybutadiene rubber (BR), etc. | Introduced during the mixing stage alongside other additives to minimize polymer chain scission and crosslinking induced by shear heating, improving compound flow behavior and storage stability |
| Engineering Plastics | Long-term heat stabilizer for polyamides (PA6, PA66) and polyesters (PBT, PET) | Added during melt compounding and extrusion; used in conjunction with copper inhibitors to significantly enhance long-term thermal aging resistance at 150–200 °C |
Manufacturing Quality Control of 151841-65-5
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 210-230 nm based on peak area comparison with reference standard. |
| Moisture Content | Karl Fischer Titration | Electrochemical titration measuring water content via iodine-sulfur dioxide reaction in anhydrous methanol-based solvent. |
| Residue on Ignition | Gravimetric Analysis | Determination of inorganic ash content by high-temperature incineration followed by weighing of residual mass. |
| Heavy Metals (Pb, Cd, Hg, Cr) | ICP-OES | Multi-element quantification after acid digestion using inductively coupled plasma optical emission spectroscopy. |
| Aluminum Content | Complexometric Titration | Titration with EDTA at controlled pH using xylenol orange indicator to determine Al3+ concentration. |
| Phosphorus Content | UV-Vis Spectrophotometry | Measurement of phosphomolybdate complex absorbance at ~820 nm after oxidation and complex formation. |
