It has also found use as a plasticizer. Bisphenol A is difunctional and used to produce epoxy resin and polycarbonate. 4-tert-Butylphenol is monofunctional and so in polymer science terms, bisphenol A is a polymer chain extender but 4-tert-butylphenol is a chain stopper or sometimes called endcapper. It is thus use to control molecular weight ...
[4] Since chemical expertise is required to create a functional chemical leaven without producing off-flavors from the chemical precursors involved, such substances are often mixed into premeasured combinations for maximum results. These are generally referred to as baking powders. Sour milk and carbonates were used in the 1800s.
2,4-Di-tert-butylphenol (2,4-DTBP) is a white solid with a phenolic odour. It is primarily used as a raw material for the production of several commercially important antioxidants and phenolic benzotriazole-type UV absorbers. It also finds use as a starting material in the synthesis of agrochemicals, fragrances and catalysts (i.e. Jacobsen's ...
the parent compound, used as a disinfectant and for chemical synthesis: Bisphenol A: and other bisphenols produced from ketones and phenol / cresol BHT (butylated hydroxytoluene) - a fat-soluble antioxidant and food additive: 4-Nonylphenol: a breakdown product of detergents and nonoxynol-9: Orthophenyl phenol: a fungicide used for waxing citrus ...
Bis(2,4-di-tert-butylphenyl) pentaerythritol diphosphite is an organophosphite used as a polymer stabilizer in plastics. Like other phosphite antioxidants it primarily acts to remove hydroperoxides and is typically used in combination with hindered phenolic antioxidants such as pentaerythritol tetrakis(3,5-di-tert-butyl-4-hydroxyhydrocinnamate) .
Atmospheric oxygen, used during natural aging of flour; Use of chlorine, bromates, and peroxides is not allowed in the European Union. [1] Bleached flour improves the structure-forming capacity, allowing the use of dough formulas with lower proportions of flour and higher proportions of sugar [citation needed].
Para tertiary butylphenol formaldehyde resin, also known as p-tert-butylphenol-formaldehyde resin (PTBP-FR), is a thermoplastic phenol-formaldehyde resin found in commercial adhesives, particularly glues used to bond leather and rubber. It has broad usage in a large variety of industries and can be found in many household textile products and ...
This white solid is a widely used stabilizer in polymers where it functions as a secondary antioxidant. It also reduces discoloration (yellowing) of plastics. The compound is a phosphite ester formed by the reaction of 2,4-di-tert-butylphenol with phosphorus trichloride. [1] It is an approved food contact materials in the US. [2]
