2-Methyl-2-pentanol (IUPAC name: 2-methylpentan-2-ol) is an organic chemical compound. It can be added to a gas chromatograph to help distinguish between branched compounds, especially alcohols. [2] Its presence in urine can be used to test for exposure to 2-methylpentane. [3]
Three of these alcohols, 2-methyl-1-butanol, 2-pentanol, and 3-methyl-2-butanol (methyl isopropyl carbinol), contain stereocenters, and are therefore chiral and optically active. The most important amyl alcohol is isoamyl alcohol , the chief one generated by fermentation in the production of alcoholic beverages and a constituent of fusel oil .
Al(C 14 H 29) 3 + 3 ⁄ 2 O 2 + 3 ⁄ 2 H 2 O → 3 HOC 14 H 29 + 1 ⁄ 2 Al 2 O 3. Alternatively ethylene can be oligomerized to give mixtures of alkenes, which are subjected to hydroformylation, this process affording odd-numbered aldehyde, which is subsequently hydrogenated. For example, from 1-decene, hydroformylation gives the C 11 alcohol:

When necessary, the position of the hydroxyl group is indicated by a number between the alkane name and the -ol: propan-1-ol for CH 3 CH 2 CH 2 OH, propan-2-ol for CH 3 CH(OH)CH 3. If a higher priority group is present (such as an aldehyde , ketone , or carboxylic acid ), then the prefix hydroxy- is used, [ 19 ] e.g., as in 1-hydroxy-2 ...
tert-Amyl alcohol (TAA) or 2-methylbutan-2-ol (2M2B), is a branched pentanol. Historically, TAA has been used as an anesthetic [ 3 ] and more recently as a recreational drug . [ 4 ] TAA is mostly a positive allosteric modulator for GABA A receptors in the same way as ethanol . [ 5 ]
CO + 2 H 2 → CH 3 OH. which is the same as listed above. In a process closely related to methanol production from synthesis gas, a feed of hydrogen and CO 2 can be used directly. [55] The main advantage of this process is that captured CO 2 and hydrogen sourced from electrolysis could be used, removing the dependence on fossil fuels.
2-Methyl-1-pentanol (IUPAC name: 2-methylpentan-1-ol) is an organic chemical compound. It is used as a solvent and an intermediate in the manufacture of other chemicals. [ 2 ] Due to its low solubility in water it has recently been suggested as a solvent in liquid–liquid extraction of ethanol from fermented feedstocks.
