2. Application
As an antioxidant, it can inhibit or delay the oxidation degradation of plastics or rubber, thereby extending their service life. It can prevent the increase in acid value or viscosity of lubricating oil and fuel oil. As a food additive, it can delay the spoilage of food. This product is also a stabilizer for synthetic rubber (styrene-butadiene, nitrile, polyurethane, isoprene, etc.), polyethylene, and polyvinyl chloride. BHT is also a widely used oil-soluble antioxidant both domestically and internationally. Due to its strong antioxidant capacity, good heat resistance and stability, no specific odor, no color reaction with metals, and low price, it is the main antioxidant in China. China stipulates that it can be used in edible oils, fried foods, biscuits, with a maximum usage of 0.2g/kg.
2,6-Dibutylhydroxytoluene (BHT) is used as an antioxidant. It can react with the chain-growth free radicals in auto-oxidation to eliminate the free radicals and thus interrupt the chain reaction. In the process of antioxidation, 2,6-Dibutylhydroxytoluene (BHT) can act as both a hydrogen donor and a free radical capturer. Due to the presence of two strong electron-donating groups at the 2 and 6 positions, 2,6-Dibutylhydroxytoluene (BHT) has a very strong antioxidant effect.
