2,6-Di-tert-butyl-4-methylphenol
1. Basic Information
Name: 2,6-Di-tert-butyl-4-methylphenol
Alias: BHT, Butylated Hydroxytoluene
CAS No.: 128-37-0
Molecular Formula: C15H24O
Molecular Weight: 220.35
2. Physical and Chemical Properties
Physical Properties
- Appearance: White crystalline powder or flake solid
- Odor: Slight characteristic phenolic odor
- Solubility: Soluble in CH3OH, C2H5OH, acetone, mineral oil, vegetable oil; insoluble in H2O
- Melting Point: 69–71 °C
- Boiling Point: 265 °C
- Hygroscopicity: Non-hygroscopic under normal ambient humidity
- Aqueous Characteristic: Lipophilic antioxidant, cannot dissolve in water without emulsifier
Chemical Properties
- Molecular Structure: Phenol with two tert-butyl groups at ortho positions and one methyl group at para position
- Antioxidant Mechanism: Phenolic hydroxyl captures free radicals to terminate auto-oxidation chain reaction
- Acid-base Stability: Stable under neutral and weak acid/alkali conditions; reacts with strong alkali to form phenate
- Thermal Stability: Stable below 150 °C, suitable for plastic, oil high-temperature processing
- Photostability: Gradually turns yellow under long-term UV irradiation
- Compatibility: Excellent compatibility with plastics, rubber, grease and flavors; incompatible with strong oxidants
3. Main Application Fields
