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 ...
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 ...
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 ...
Alkylphenols are xenoestrogens. [3] Long chain Alkylphenols have the most potent estrogenic activity. [3] The European Union has implemented sales and use restrictions on certain applications in which nonylphenols are used because of their alleged "toxicity, persistence, and the liability to bioaccumulate" but the United States EPA has taken a slower approach to make sure that action is based ...
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]
In the laboratory, concentrated hydrochloric acid is used. ... tert-Butyl chloride is used to prepare the antioxidant tert-butylphenol and the fragrance neohexyl ...
Pentaerythritol tetrakis(3,5-di-tert-butyl-4-hydroxyhydrocinnamate) is a chemical compound composed of four sterically hindered phenols linked through a pentaerythritol core. It is used as primary antioxidant for stabilizing polymers , particularly polyethylene and polypropylene .
Its dominant use is as an antioxidant. 2,6-di-tert-butylphenol is a precursor to more complex compounds used as antioxidants and light-protection agents for the stabilization for polymers. Of particular note is methyl-3-(3,5-di-tert-butyl-4-hydroxyphenyl)-propionate (CAS# 6386-38-5), which is formed by the Michael addition of methyl acrylate.
