A Tipler cylinder is used as a plot device in Chuck Grossart's story "The Phoenix Descent". Episode 9 of the webseries Ask Weathersby [14] mentions the Tipler cylinder, discussing time travel. [15] In "The Miracle of Christmas", Episode 2.11 of the American TV series Timeless, a Tipler cylinder is mentioned as being added to an upgraded time ...
2,4-Di-tert-butylphenol (2,4-DTBP) is a white solid with a phenolic odour.It is primarily used as a raw material for the production of several commercially important antioxidants and phenolic benzotriazole-type UV absorbers.
The best-selling drug in the U.S., Acetaminophen, also known as Paracetamol, is a phenol. There are various classification schemes. [15]: 2 A commonly used scheme is based on the number of carbons and was devised by Jeffrey Harborne and Simmonds in 1964 and published in 1980: [15]: 2 [16]
Mechanochemistry is not the same as mechanosynthesis, which refers specifically to the machine-controlled construction of complex molecular products. [ 2 ] [ 3 ] In natural environments, mechanochemical reactions are frequently induced by physical processes such as earthquakes, [ 4 ] glacier movement [ 5 ] or hydraulic action of rivers or waves.
[6] [7] Due to the two step nature, the Raschig–Hooker process can be used to produce either chlorobenzene or phenol. Reaction scheme of the Raschig-Hooker process. The Raschig–Hooker process's ability to make phenol makes it comparable to other methods, such as the Dow and Bayer process, which also converts benzene into phenol. In fact ...
It also has hemostatic and antiseptic qualities that make it ideal for this use. Phenol spray, usually at 1.4% phenol as an active ingredient, is used medically to treat sore throat. [38] It is the active ingredient in some oral analgesics such as Chloraseptic spray, TCP and Carmex. [39]
The reaction can be used for the synthesis of 2,6-di-tert-butyl-4-methoxyphenol, which is frequently used as an antioxidant. Synthese von 2,6-Di- tert -butyl-4-methoxyphenol aus 2,4,6-TTBP 2,4,6-TTBP is used as stabilizers , free-radical scavengers and antioxidants in technical applications, such as in fuels , hydraulic fluids and lubricating ...
Gossypol (/ ˈ ɡ ɒ s ə p ɒ l /) is a natural phenol derived from the cotton plant (genus Gossypium). Gossypol is a phenolic aldehyde that permeates cells and acts as an inhibitor for several dehydrogenase enzymes. It is a yellow pigment. The structure exhibits atropisomerism, with the two enantiomers having different biochemical properties. [1]
