Polymerization inhibitors MTBHQ, as an efficient polymerization inhibitor, plays a crucial role in the chemical industry. It can effectively prevent or slow down the polymerization reaction, thus ensuring the quality and stability of polymer products. The mechanism of action of Polymerization Inhibitors MTBHQ lies in its ability to react with free radicals in the polymerization reaction, thereby interrupting the growth of the polymerization chain. Free radicals are key species in the polymerization reaction that initiate chain reactions leading to the growth of polymer molecular chains.

Product Parameters2-tert-butylhydroquinone as a food additive, TBHQ has been used in the United States and other more than 20 countries, China in 1992 was approved for use in oil and fat-containing foods, thousands of fish products, biscuits, quick-cooking noodles, canned fat-containing foods, cured meat products and so on.

 It is a white to light gray crystalline or crystalline powder with a very slight special odor. It is soluble in ethanol, acetic acid, ethyl ester, isopropanol, ether, and oils, and is almost insoluble in water (25 ℃,<1%; 95 ℃, 5%). TBHQ is an oil soluble antioxidant that can prevent or delay the oxidation and deterioration of fats in food.

Possible reaction pathways of 2,5-di-tert-butyl-hydroquinone (2,5-DTBHQ).Valgimigli et al. proposed a mechanism wherein semiquinone (2) reacts with molecular oxygen to produce 2,5-di-tert-butyl-1,4-benzoquinone (2,5-DTBBQ) and hydroperoxyl radical (HOO∙). The semiquinone (2) terminates a second propagation chain via either hydrogen abstraction (Reaction II) or addition reaction (Reaction IV) and these reaction pathways play a very critical role in the inhibition process.

There are two types of antioxidants, one is chemical synthesized and the other is natural antioxidants.       Chemical synthesis, such as BHT, BHQ, TBHQ, ethoxyquinoline, PE, etc., these are considered to be called chemical synthesis of antioxidants, these antioxidants have been banned in Europe, that in China and the United States, is the amount of additive per kilogram can not be greater than 0.2, these chemical synthesis of antioxidants, it is true that there is now some controversy, but the antioxidant effect is relatively good.

1.Product CharacteristicsTertiary butylhydroquinone(TBHQ), white or slightly reddish brown crystalline powder, has a very light special fragrance, almost insoluble in water (about 5 per cent), soluble in ethanol, ethyl acetate, ether and other organic solvents.Tertiary butylhydroquinone has synergistic properties and can be used synergistically with other antioxidants (e.g. BHA, B HT) as well as chelating agents (e.g.

Especially in areas with high room temperature, such as some southern regions of China, the sourness and flavor of instant noodles have become a hot topic of concern for instant noodle production enterprises and consumers. Therefore, appropriate selection of antioxidants can inhibit the rancidity of oily food production and prolong the storage life of the product. Shelf life is considered an effective way to prevent the product from deteriorating due to oxidation.

Oil and grease antioxidant TBHQMolecular formula: C10H14O2Molecular weight: 166.22CAS No.: 1948-33-0TBHQ is an efficient and safe food antioxidant, which has been approved for use in more than one hundred countries and regions around the world, such as Europe, America, Asia, Australia, Africa, etc.

Oil and grease antioxidant TBHQMolecular method: c10h14o2Molecular weight: 166.22Cas no: 1948-33-zeroTBHQ is a good and secure food antioxidant, which has been accepted to be used in multiple hundred international locations and regions around the world, together with europe, the usa, asia, australia, africa, etc.

At present, the most commonly used antioxidants for oils and their products are BHA, BHT, PG, TBHQ, and tocopherols. As for vegetable oils, their antioxidant capacity is in the order of TBHQ>PG>BHT>BHA. As for animal fats, the order of their antioxidant capacity is TBHQ>PG>BHA>BHT. For anhydrous milk fat, their antioxidant capacity is in the order of PG>TBHQ>BHA>tocopherols.

Product FeaturesThe antioxidant effect of this product is very ideal, 5~7 times stronger than BHA, BHT, PG. It is suitable for animal and vegetable fats and fat-rich foods, especially for vegetable oils, and is the preferred antioxidant for salad oil, blending oil and high cooking oil. It can effectively delay the oxidation of fats and oils, improve the stability of foods, and significantly extend the shelf life of fats and fat-rich foods.

Introduction of nature:TBHQ is sort of insoluble in water (approximately five‰), soluble in ethanol, acetic acid, ethanol, isopropyl alcohol, ether and vegetable oil, lard, and so forth. Nearly insoluble in water (25℃, <1%). Boiling factor 295℃, melting factor 126 -128.5℃. It has the effect of stopping the failure of most fats and oils, specially vegetable oils. It does no longer trade color in touch with iron and copper, but can turn red if alkali is present.

The seed method first completely dissolves TBHQ in a small amount of oil or 95% alcohol solution, and prepares 5-10% TBHQ oil or alcohol solution.

The main cause of food deterioration during processing, transportation and storage is lipid oxidation, and the addition of antioxidants is the main means of delaying the oxidation of oil and fat products. Antioxidant is a free radical trapping agent, when it plays an antioxidant role, it can provide active hydrogen to combine with free radicals generated during oxidation of fats and oils, so that the free radicals are converted into stable compounds, blocking the free radical chain reaction, inhibiting lipid peroxidation, slowing down the oxidation of fats and oils and deterioration.

TBHQ can be used for edible oils, fried foods, dried fish products, biscuits, instant noodles, instant boiled rice, canned dried fruits, pickled meat products.This product does not affect the color and flavor of food, and is not used for coloring iron containing foods.The antioxidant effect of this product is very ideal, 5-7 times stronger than BHA, BHT, and PG.

TBHQ has good oil solubility and thermal stability, and does not change in color after heating.They are only suitable for high water content oil and fat foods such as biscuits, instant noodles, artificial milk oil, and mayonnaise. When the oil contains a large amount of metal ions and oxygen, the addition of antioxidants can inhibit the formation of peroxides.Oxidized fish oil is harmful to human health, so it is important to prevent oxidation and improve the stability of fish oil.
