    en.wikipedia.org/wiki/Tris(3,5-di-tert-butyl-4...

    Tris(3,5-di-tert-butyl-4-hydroxybenzyl) isocyanurate is a high molecular weight additive, with low volatility. It is well suited to stabilising polyolefins against degradation caused by long term heat aging. [1] It is an approved food contact material in the US. [2]

    Octadecyl 3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate is significantly less volatile than simpler phenolic antioxidants such as butylhydroxytoluene (BHT). This makes it more suitable to stabilising plastics, as it is not driven out by the high temperatures experienced during plastic extrusion and moulding, [2] when they are heated to 150-320 °C (300–600 °F). [3]

  6. 4-tert-Butylphenol - Wikipedia

    en.wikipedia.org/wiki/4-tert-Butylphenol

    4-tert-Butylphenol is an organic compound with the formula (CH 3) 3 CC 6 H 4 OH. It is one of three isomeric tert-butyl phenols. It is a white solid with a distinct phenolic odor. It dissolves in basic water. [2]

  7. Butylated hydroxytoluene - Wikipedia

    en.wikipedia.org/wiki/Butylated_hydroxytoluene

    The chemical synthesis of BHT in industry has involved the reaction of p-cresol (4-methylphenol) with isobutylene (2-methylpropene), catalyzed by sulfuric acid: [11] CH 3 (C 6 H 4)OH + 2 CH 2 =C(CH 3) 2 → ((CH 3) 3 C) 2 CH 3 C 6 H 2 OH. Alternatively, BHT has been prepared from 2,6-di-tert-butylphenol by hydroxymethylation or aminomethylation ...

    en.wikipedia.org/wiki/Butyl_group

    The effect of the tert-butyl group on the progress of a chemical reaction is called the Thorpe–Ingold effect illustrated in the Diels-Alder reaction below. Compared to a hydrogen substituent, the tert-butyl substituent accelerates the reaction rate by a factor of 240. [2] tert-Butyl effect. The tert-butyl effect is an example of steric hindrance.
