Industrial Applications of 4,4'-Butylidenebis(6-tert-butyl-3-methylphenol)
| Industry | Application | Process |
|---|---|---|
| Plastics Industry | Antioxidant for thermal and long-term thermo-oxidative stabilization of polyolefins (e.g., polyethylene, polypropylene) | Added by compounding with the resin during polymerization or prior to pelletization; typical dosage: 0.1–0.5 wt% |
| Rubber Industry | Anti-aging agent to inhibit thermo-oxidative degradation of vulcanized rubber during processing and service life | Incorporated into the compound during the mixing stage, used synergistically with accelerators and sulfur |
| Lubricating Oils & Greases | High-temperature antioxidant additive to retard oxidative degradation of base oils | Added during the blending stage to mineral or synthetic hydrocarbon base oils; typical concentration: 0.1–0.3 wt% |
| Adhesives & Sealants | Enhances thermal stability and long-term weather resistance; prevents discoloration and embrittlement in phenolic resin systems | Formulated in combination with other stabilizers during recipe development and added prior to heat curing |
Manufacturing Quality Control of 4,4'-Butylidenebis(6-tert-butyl-3-methylphenol)
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification by comparison of peak area against a certified reference standard using UV detection at 280 nm. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid transitions to liquid, following ASTM D1565 or ISO 6383-2. |
| Appearance | Visual Inspection | Assessment of physical state and color under controlled lighting against established reference samples. |
| Moisture Content | Karl Fischer Titration | Electrochemical titration using iodine generation to quantify water content based on stoichiometric reaction. |
