Uses | 6-tert-butyl-2, 4-dimethylphenol is an alkylated phenol, used in industry as an antioxidant, such as preventing adhesion in fuel, and as a UV stabilizer. It is used for jet fuel, gasoline and gas. It is a transparent liquid with a melting point of 21-23 ℃ and a boiling point of 248-249 ℃. It is also used in the printing industry. It is stable in acidic, neutral and alkaline solutions and is not prone to biodegradation. It does not absorb ultraviolet light, so it cannot directly photodegrade. 2, 4-dimethyl-6-tert-butylphenol is a substance that can quickly interact with free radicals to terminate the chain reaction. It is a new type of high temperature resistant aviation fuel antioxidant, acrylic acid inhibitor, Also often called stabilizer, it is an intermediate of a variety of polymer antioxidants, and it is also a very important pharmaceutical intermediate. It is found in antioxidant mixtures AO-30, AO-31, AO-32, IONOL K72, IONOL K78, IONOL K98 and other substances. Respiratory toxicity is suspected, and neurotoxicity is also suspected. TA-24M6B can be used as an antioxidant in polymer resin and aviation fuel, and can also be used as a pharmaceutical intermediate, and can be used as a polymerization inhibitor in MMA, UV photocuring monomer, resin and unsaturated resin, especially at high temperature. It is a new type of high temperature resistant aviation fuel antioxidant, acrylic polymerization inhibitor, and also a very important pharmaceutical intermediate |
