4-Phenylphenol is a flammable, difficult to ignite, white, scaly solid with a phenol-like odor that is very slightly soluble in water. [3] References
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.
Phenyl isocyanate is an organic compound typically abbreviated PhNCO. The molecule consists of a phenyl ring attached to the isocyanate functional group. It is a colourless liquid that reacts with water. Phenyl isocyanate has a strong odor and tearing vapours, therefore it has to be handled with care.
4-Isopropenylphenol is an organic compound with the formula CH 2 =(CH 3)CC 6 H 4 OH. The molecule consists of a 2-propenyl group (CH 2 = C -CH 3 ) affixed to the 4 position of phenol . The compound is an intermediate in the production of bisphenol A (BPA), 2.7 Mkg/y of which are produced annually (2007).
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 .
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 ...
In 1834, German chemist Friedlieb Ferdinand Runge discovered a phenol, also known as carbolic acid, which he derived in an impure form from coal tar.In August 1865, Joseph Lister applied a piece of lint dipped in carbolic acid solution to the wound of an eleven-year-old boy at Glasgow Royal Infirmary, who had sustained a compound fracture after a cart wheel had passed over his leg.
Ethylphenol (4-EP) is an organic compound with the formula C 2 H 5 C 6 H 4 OH. It is one of three isomeric ethylphenols. A white solid, it occurs as an impurity in xylenols and as such is used in the production of some commercial phenolic resins. It is also a precursor to 4-vinylphenol. [3]
