tert-Butylbenzene is an organic compound classified as an aromatic hydrocarbon. Its structure consists of a benzene ring substituted with a tert -butyl group . It is a flammable colorless liquid which is nearly insoluble in water but miscible with organic solvents.
The saturated compounds have formula C 10 H 14 and molecular weight 134.22 g/mol. C 4-benzenes are found in petroleum. [1] ... tert-Butylbenzene; Isobutylbenzene ...
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.
For this reason di-tert-butyl peroxide is commonly used as a radical initiator in organic synthesis and polymer chemistry. The decomposition reaction proceeds via the generation of methyl radicals. (CH 3) 3 COOC(CH 3) 3 → 2 (CH 3) 3 CO • (CH 3) 3 CO • → (CH 3) 2 CO + CH • 3 2 CH • 3 → C 2 H 6
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 .
4-tert-Butylcatechol (TBC) is an organic chemical compound which is a derivative of catechol. [1] TBC is available in the form of a solid crystal flake [ 2 ] and 85% solution in methanol [ 3 ] or water.
The European Food Safety Authority (EFSA) and the United States Food and Drug Administration (FDA) [3] have evaluated TBHQ and determined that it is safe to consume at the concentration allowed in foods. [4] The FDA [5] and European Union [4] both set an upper limit of 0.02% (200mg/kg) of the oil or fat content in foods. At very high doses, it ...
