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. This compound is used as a feedstock in the synthesis of more complex antioxidants such as Irganox 1098 . 2,6-Di- tert -butylphenol is also used in the synthesis of CGP-7930 , probucol , and ...
Properties. 2,4,6-Tri- tert -butylphenol is a white solid which dissolves in many organic solvents, but not in aqueous or alcoholic alkaline solutions. The green-blue coloring with iron (III)chloride, which is characteristic for phenols, does not occur in 2,4,6-TTBP. The compound is oxidizable in air but practically non-biodegradable.
2,6-Di-tert-butylpyridine is an organic compound with the formula (Me 3 C) 2 C 5 H 3 N. This colourless, oily liquid is derived from pyridine by replacement of the two H atoms with tert-butyl groups. It is a hindered base. [1] For example, it can be protonated, but it does not form an adduct with boron trifluoride.
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 ...
Methyl tert-butyl ether (MTBE), also known as tert-butyl methyl ether, is an organic compound with a structural formula (CH 3) 3 COCH 3. MTBE is a volatile, flammable, and colorless liquid that is sparingly soluble in water. [ 1 ] Primarily used as a fuel additive, MTBE is blended into gasoline to increase its octane rating and knock resistance ...
Inscription. 2020. Pantun (Jawi: ڤنتون) is a Malayic oral poetic form used to express intricate ideas and emotions. [1] It generally consists of even-numbered lines [2] and based on ABAB rhyming schemes. [3] The shortest pantun consists of two lines better known as the pantun dua kerat in Malay, while the longest pantun, the pantun enam ...
Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). Pentaerythritol tetrakis (3,5-di-tert-butyl-4-hydroxyhydrocinnamate) is a chemical compound composed of 4 sterically hindered phenols linked through a pentaerythritol core. It is used as primary antioxidant for stabilizing polymers ...
tert-Butyl alcohol is the simplest tertiary alcohol, with a formula of (CH 3) 3 COH (sometimes represented as t -BuOH). Its isomers are 1-butanol, isobutanol, and butan-2-ol. tert -Butyl alcohol is a colorless solid, which melts near room temperature and has a camphor -like odor. It is miscible with water, ethanol and diethyl ether.
