Usage

Antioxidant properties

Prevents oxidation of fats and oils, extends shelf life of products BHT is used as an antioxidant in various industries, such as food, cosmetics, and pharmaceuticals, to prevent the oxidation of fats and oils, which in turn extends the shelf life of these products.

Inhibition of free radicals

Reduces the formation of free radicals BHT works by inhibiting the formation of free radicals, which are unstable molecules that can cause damage to cells and contribute to the aging process and various diseases.

Stabilizer in manufacturing

Rubber, plastics, electrical transformer oil BHT is also used as a stabilizer in the production of rubber, plastics, and electrical transformer oil, helping to prevent the degradation of these materials and maintain their quality.

FDA approval

Approved for use as a food additive The United States Food and Drug Administration (FDA) has approved BHT for use as a food additive, meaning it is considered safe for consumption within certain limits.

Safety concerns

Potential health risks with high levels of consumption Some studies have raised concerns about the potential health risks associated with high levels of BHT consumption, including possible links to cancer and hormone disruption.

Good manufacturing practices

Generally recognized as safe when used properly BHT is considered generally recognized as safe (GRAS) when used in accordance with good manufacturing practices, which ensures that it is used in appropriate amounts and under proper conditions to minimize potential health risks.

Controlling the catalytic aerobic oxidation of phenols

The oxidation of phenols is the subject of extensive investigation, but there are few catalytic aerobic examples that are chemo- and regioselective. Here we describe conditions for the ortho-oxygenation or oxidative coupling of phenols under copper (Cu)-catalyzed aerobic conditions that give rise to ortho-quinones, biphenols or benzoxepines. We demonstrate that each product class can be accessed selectively by the appropriate choice of Cu(I) salt, amine ligand, desiccant and reaction temperature. In addition, we evaluate the effects of substituents on the phenol and demonstrate their influence on selectivity between ortho-oxygenation and oxidative coupling pathways. These results create an important precedent of catalyst control in the catalytic aerobic oxidation of phenols and set the stage for future development of catalytic systems and mechanistic investigations.

Synthesis of salicylaldehydes bearing bulky substituents in the positions 3 and 5

Reaction of 2,4-disubstituted phenols with paraformaldehyde in the presence of SnCl4 and 2,6-lutidine afforded a number of new salicylaldehydes, containing bulky substituents (tert-butyl, 1-phenylethyl, 1-(4-tert- butylphenyl)ethyl, α-cumyl, and trityl) in the positions 3 and 5.

Preparation of Some 2-(2' H-Benzotriazol-2'-yl)phenol Ultraviolet Absorbers: Application of the Transalkylation Reaction

When 2-(2' H-benzotriazol-2'-yl)phenols containing t-alkyl substituents are warmed in toluene solution with an aluminium chloride/nitromethane catalyst, the t-alkyl groups are transferred to the solvent (toluene).This transalkylation reaction has been used to prepare not readily accessible or previously inaccessible 2-(2' H-benzotriazol-2'-yl)phenols, a class of ultraviolet absorbers widely used in industry.
