The term "methyl" was derived in about 1840 by back-formation from "methylene", and was then applied to describe "methyl alcohol". This was shortened to "methanol" in 1892 by the International Conference on Chemical Nomenclature. [29] The suffix-yl, which, in organic chemistry, forms names of carbon groups, is from the word methyl.
Alcohol is also converted into phosphatidylethanol (PEth, an unnatural lipid metabolite) by phospholipase D2. This metabolite competes with PIP 2 agonist sites on lipid-gated ion channels. [28] [29] The result of these direct effects is a wave of further indirect effects involving a variety of other neurotransmitter and neuropeptide systems. [25]
With proper antifreeze, a wide temperature range can be tolerated by the engine coolant, such as −34 °F (−37 °C) to +265 °F (129 °C) for 50% (by volume) propylene glycol diluted with distilled water and a 15 psi pressurized coolant system. Early engine coolant antifreeze was methanol (methyl alcohol).
The term cycle is used because aside of water, hydrogen and oxygen, the chemical compounds used in these processes are continuously recycled. If work is partially used as an input, the resulting thermochemical cycle is defined as a hybrid one.
The United States Auto Club bans gasoline and switches all cars to methyl alcohol (methanol), a rule which would stay for 41 years before ending after the 2005 race. During the Nigerian Civil War of 1967 to 1970, Engineers in the breakaway republic of Biafra resorted to powering vehicles with alcohol. Initially, alcohol was used to supplement ...
According to state law, there are four forms of acceptable identification you can show to prove you are old enough to buy alcohol: A driver’s license. A special identification card.
In other less formal contexts, an alcohol is often called with the name of the corresponding alkyl group followed by the word "alcohol", e.g., methyl alcohol, ethyl alcohol. Propyl alcohol may be n-propyl alcohol or isopropyl alcohol, depending on whether the hydroxyl group is bonded to the end or middle carbon on the straight propane chain. As ...
