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.

The unsaturated resin polymerization inhibitor MTBHQ (2-tert-butylhydroquinone) plays an important role in resin synthesis and other synthetic reactions. The following is a detailed analysis of its principle of action and effects:Effect Remarkable polymerization inhibition effect: MTBHQ is a kind of high efficient polymerization inhibitor for unsaturated resin. Under normal storage conditions, the general addition amount is only two ten-thousandths of the total amount of resin, and it can play a good effect of polymerization inhibition.

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.

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.

At high temperatures, a series of complex chemical reactions such as oxidation, decomposition, polymerization, and hydrolysis are prone to occur, resulting in a rapid increase in the acid value, peroxide value, and carbon base value of roasted foods. In the later stage of storage and sales, unpleasant odors are easily produced. The use of TBHQ can effectively delay oil oxidation in pastry foods.Baked pastry foods require a higher temperature during the baking process, such as cakes and bread, which require a baking temperature of 160C~190C.
