2.6-Di-Tertiary Butyl Para-Cresol, (DTBPC) is a white to off-white crystalline solid with a mild aromatic odor.
It is a member of the cresol family of compounds and is used as an antioxidant in various industrial applications, also used as an intermediate in the production of other chemicals which are used as fragrances and dyes.
It is considered to be a relatively safe industrial chemical when handled and stored appropriately as exposure can be minimized through a variety of means.
It is a combustible material and should be stored away from sources of heat, sparks, or open flames.
It has good antioxidation, can effectively prolong the induction time and display the obvious antioxidation effect at the working temperature below 100°C.
2.6-di-Tertiary Butyl Para-Cresol is used for blending industrial gear oils, antiwear hydraulic oils, turbine oils, transformer oils, machine tool oils and fuel oils
2.6-di-Tertiary Butyl Para-Cresol is an antioxidant and stabilizer that is commonly used in the rubber and plastics industry. It helps to prevent degradation and oxidation of polymers, ensuring that the materials remain durable and resistant to aging.
This compound works by inhibiting the free radicals that can cause oxidative degradation. It scavenges these free radicals and prevents them from reacting with the polymer chains, which would lead to chain scission and degradation.
2.6-di-Tertiary Butyl Para-Cresol is especially effective in protecting materials that are exposed to heat, light, and oxygen, as these factors can accelerate the oxidative degradation process. It also enhances the resistance of rubber and plastics to weathering, UV radiation, and other environmental factors.
In addition to its use in rubber and plastics, 2.6-di-Tertiary Butyl Para-Cresol is also used as an antioxidant in other products, such as oils, lubricants, and fuels. It helps to prevent the formation of sludge, deposits, and varnish in these fluids, ensuring their optimal performance and longevity.
2,6-di-tert-butyl-p-cresol, also known as BHT (butylated hydroxytoluene), is a synthetic antioxidant commonly used in various products, including lubricating oils, fuels, food, and cosmetics. Let’s break down its name and properties:
- 2,6-di-tert-butyl: This indicates the structure of the molecule. It consists of a p-cresol (para-cresol) molecule with two tert-butyl groups attached to the 2 and 6 positions of the aromatic ring. The tert-butyl groups are bulky and provide steric hindrance, which enhances the stability of the molecule.
- Para-Cresol (p-cresol): This is an organic compound with the chemical formula C7H8O. It is a type of phenol, which is a class of aromatic organic compounds containing a hydroxyl group (-OH) attached to a benzene ring.
- Butylated Hydroxytoluene (BHT): This is the common name for 2,6-di-tert-butyl-p-cresol. BHT is widely used as an antioxidant due to its ability to inhibit the oxidation of organic materials, including oils and fats. It works by scavenging free radicals and terminating chain reactions that lead to the degradation of the substance.
In lubricating oils, BHT helps prevent the degradation of the oil due to exposure to oxygen and high temperatures during engine operation. By slowing down oxidation reactions, BHT helps extend the oil’s useful life and maintain its performance characteristics over time. It is often used in combination with other antioxidants and additives to provide comprehensive protection against degradation and corrosion in lubricating oils.
