Industrial Applications of Butylated Hydroxytoluene
| Industry | Application | Process |
|---|---|---|
| Plastics Industry | Antioxidant for resins such as polyethylene, polypropylene, and polyvinyl chloride | Added during polymerization or blended with the resin during molten processing and pelletization |
| Rubber Industry | Antidegradant for natural rubber and synthetic rubbers (e.g., styrene-butadiene rubber, cis-polybutadiene rubber) | Incorporated into the compound during mixing or vulcanization to prevent thermal-oxidative aging |
| Petroleum Industry | Antioxidant stabilizer for gasoline, transformer oil, lubricating oils, and other petroleum products | Directly added to the finished oil to inhibit oxidation and extend service life |
| Food Industry | Food additive (antioxidant) for preventing oxidation of fats, oils, and oil-containing food products | Added within permitted limits per food hygiene standards to oils, fried foods, or dried fish products |
| Cosmetics Industry | Antioxidant in skincare products and lipsticks to prevent base material rancidity | Added during emulsification and homogenization |
| Textile, Printing & Dyeing Industry | Aging resistance and discoloration prevention for synthetic fibers (e.g., nylon, polypropylene fiber) | Added during spinning or finishing |
Manufacturing Quality Control of Butylated Hydroxytoluene
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the sample's color and physical state. The qualified product should be a white or pale yellow crystalline powder with no visible impurities. |
| Melting Point | Capillary Melting Point Determination | Determine the melting temperature range using a melting point apparatus. The standard melting point of antioxidant 264 is approximately 69–71°C. |
| Content (Purity) | High-Performance Liquid Chromatography (HPLC) | Separate using a C18 column and detect at UV wavelength (e.g., 280 nm). Quantify the main component by external standard method, requiring ≥99.0% purity. |
| Moisture Content | Karl Fischer Titration | Determine trace moisture content via coulometric or volumetric Karl Fischer titration. Typically requires ≤0.1%. |
| Volatile Matter | Loss on Drying | Dry the sample at a specified temperature (e.g., 105°C) to constant weight, then calculate the percentage of mass loss to assess volatile impurities. |
| Color | Platinum-Cobalt Colorimetry or Colorimeter Method | Compare the sample solution visually against standard color grades, or use a colorimeter to measure L*a*b* values to ensure color consistency. |
| Free Phenol (Impurities) | Spectrophotometry or HPLC | Quantify unreacted phenolic impurities using chromogenic reactions (e.g., 4-aminoantipyrine) or chromatographic separation. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or ICP-MS | After sample digestion, determine total levels of heavy metals such as lead, arsenic, and mercury. Must comply with pharmacopoeial or industry limits (e.g., ≤10 ppm). |
| Sulfate Ash | Residue on Ignition | Add sulfuric acid to char the sample, then ignite at high temperature. Weigh the residual ash to assess inorganic impurities; typically requires ≤0.1%. |
| Related Substances (Impurity Profile) | HPLC (Gradient Elution) | Use gradient elution to separate and detect synthetic by-products or degradation products, such as 2,4-di-tert-butylphenol. |
