Antioxidant 264 CAS 128-37-0, its chemical name Butylated hydroxytoluene, often referred to as BHT, is a phenolic compound, as can be seen from the name. Its molecular formula is C15H24O and its molecular weight is 220.35. From the appearance, it is a white crystalline powder, no special odor, more stable at room temperature.
Before understanding its application, let’s start with its structure. In the molecular structure of butylated hydroxytoluene CAS 128-37-0, the phenolic hydroxyl group is a key part of its antioxidant effect. The hydrogen atoms on the phenolic hydroxyl group are relatively active, which can provide hydrogen atoms to combine with free radicals, thus interrupting the free radical chain reaction and achieving the purpose of antioxidant. At the same time, the presence of two tert-butyl groups and a methyl group in the molecule increases the steric hindrance of the molecule, making the phenolic hydroxyl group more difficult to oxidize, and also enhances the stability of antioxidant 264 itself. antioxidant 264 CAS 128-37-0 can play a powerful antioxidant effect, mainly because it can trap free radicals, the free radicals formed by themselves due to the steric hindrance effect of tert-butyl and methyl groups in the molecule, become relatively stable, and it is not easy to cause new free radical chain reactions, which makes it able to continue to play an antioxidant role and effectively protect substances from oxidation.
Food field
Butylated hydroxytoluene CAS 128-37-0 is widely used in the food field. Cooking oil is easy to be oxidized, and the oxidized cooking oil not only tastes worse, but also produces some harmful substances to the human body. Adding an appropriate amount of antioxidant 264 can effectively inhibit the oxidation rancidity of oil.
Nut food is rich in oil, which is easy to be oxidized during storage, resulting in rancid taste, affecting taste and quality. Nut manufacturers often add antioxidant 264 during processing and packaging to prevent oxidation and deterioration of nuts. In this way, after we buy nuts, even if they are placed for a period of time, we can taste their original crispy taste and enjoy the delicious and nutrition brought by nuts.
In addition, in some fried foods, baked goods, antioxidant 264 also plays an important role. For example, potato chips, cookies and other fried baked goods, they are processed at high temperatures during the processing process, and the oil is more likely to be oxidized. The addition of antioxidant 264 can slow down the oxidation rate of these foods, maintaining their crisp taste and good flavor.
Industrial field
Plastics in the process of processing and use, will be affected by heat, light, oxygen and other factors, resulting in reduced performance, aging, brittleness, discoloration and other problems. Taking polyethylene, polypropylene and other common plastics as an example, adding antioxidant 264 in the production process can effectively inhibit the oxidative degradation of plastics and improve its thermal stability and weather resistance. Many of the plastic pipes, plastic containers, plastic films, etc. used in our daily life have been added with antioxidant 264, which makes them maintain good physical properties, extend service life, and reduce replacement and maintenance costs during long-term use.
In the rubber industry, antioxidant 264 is also indispensable. Rubber products such as tires, hose, tape, etc., will be affected by oxygen, ozone, heat, mechanical stress and other factors during use, and are prone to aging. After aging, rubber products will become hard, brittle, and lose elasticity, which seriously affects its performance and safety. antioxidant 264 can effectively inhibit the thermal oxygen aging and ozone aging of rubber, and improve the anti-aging properties of rubber products.
In the process of storage and use, the paint will react with oxygen in the air, resulting in a decline in the performance of the paint, slow drying speed, discoloration of the film, powder and other problems. Adding antioxidant 264 can delay the oxidation process of the paint, maintain the stability and coating performance of the paint, so that the paint can better protect the surface of the coated object, extend its service life, and maintain a good appearance.
When storing antioxidant 264 CAS 128-37-0, pay special attention to environmental conditions. It should be kept in a cool, ventilated warehouse, away from fire and heat sources, as high temperatures may trigger its decomposition or combustion reaction. At the same time, antioxidant 264 must be stored separately from oxidants, alkalis, etc., to avoid mixed storage. This is because when it comes into contact with oxidants, it is prone to REDOX reactions, thereby losing antioxidant properties and even causing danger.
Antioxidant 264 has a wide range of production and applications worldwide. From the perspective of market size, with the continuous development of plastics, rubber, food and other industries, the demand for antioxidant 264 is also growing. Unilong is a chemical raw material manufacturer with relatively mature production technology and large production scale, which can not only produce antioxidant 264, but also alternate production of other antioxidant products at the same time to adapt to market changes. You have the intention to cooperate in purchasing please give your information, we will contact you as soon as possible.
