1. properties
1. Physical properties
2,6-di-tert-butyl-p-cresol is a white or yellowish crystalline powder with a special smell. It is insoluble in water, but soluble in ethanol, ether, acetone and other organic solvents. Its melting point is higher, generally between 69-71 ℃.
2.
of chemical properties 2,6-di-tert-butyl-p-cresol has strong antioxidant properties, which can effectively inhibit the oxidative degradation of high molecular compounds such as oils and plastics. In addition, it also has good thermal stability and can maintain its oxidation resistance under high temperature conditions.
2. uses
1.
in the plastics industry 2,6-di-tert-butyl-p-cresol as an antioxidant is widely used in the plastics industry. It can effectively prolong the service life of the plastic and prevent the aging and discoloration of the plastic caused by oxidative degradation. In polyethylene, polypropylene, polyvinyl chloride and other plastics, the addition of BHT can significantly improve its thermal stability and oxidation resistance.
2. Oil and fat industry
In the oil and fat industry, 2,6-di-tert-butyl-p-cresol is also often used as an antioxidant. It can effectively prevent the oxidative rancidity of the grease and prolong the storage period and service life of the grease. At the same time, it can also improve the thermal stability of the oil, so that it can maintain a better quality during high-temperature cooking.
3. Rubber industry
In the rubber industry, BHT can be used as an antioxidant to improve the oxidation resistance and thermal stability of rubber products and extend their service life.
4.
in the pharmaceutical industry 2,6-di-tert-butyl-p-cresol also has certain applications in the pharmaceutical industry. It can be used as a stabilizer for some drugs to prevent drugs from being degraded due to oxidation during storage and use.
In conclusion, 2,6-di-tert-butyl-p-cresol has a wide range of applications in the field of chemical production raw materials due to its unique antioxidant properties and thermal stability.
