Firstly, 2,4-dimethyl-6-tert-butylphenol is reacted with formaldehyde and HCl (Blanc reaction) to generate a chloromethyl group in the less hindered meta position. This intermediate then reacts with cyanuric acid to give the desired product.
Tris(3,5-di-tert-butyl-4-hydroxybenzyl) isocyanurate is a chemical compound used as a polymer stabilizer in plastics. Like other hindered phenols it acts as a primary antioxidant. More than 1000 tonnes per year are used in the EU.
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) .
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).

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]
Octadecyl 3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate - an inexpensive and commonly used polymer stabiliser; Tris(3,5-di-tert-butyl-4-hydroxybenzyl) isocyanurate - a polymer stabiliser commonly used to protect against long term heat aging; Irganox 1098 - a polymer stabiliser with metal chelation properties
This compound is conveniently prepared by alkylation of cyclobutadiene with tert-butyl bromide under phase-transfer conditions. [2] [1] Illustrative of the unusual complexes made possible with these bulky ligands is molecular iron nitrido complex (t Bu 3 C 5 H 2) 2 Fe 2 N 2. [3] In contrast to (C 5 Me 5) 2 Ir 2 Cl 4, (t Bu 3 C 5 H 2)IrCl 2 is ...
2,2,4,4-Tetramethyl-3-t-butyl-pentane-3-ol or tri-tert-butylcarbinol is an organic compound with formula C 13 H 28 O, ((H 3 C) 3 C) 3 COH, or t Bu 3 COH. [1] It is an alcohol that can be viewed as a structural analog of a tridecane isomer ( 2,2,4,4-tetramethyl-3- t -butylpentane ) where the central hydrogen has been replaced by a hydroxyl group ...
