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 ...
2-Methyl-1-butanol (IUPAC name, also called active amyl alcohol) is an organic compound with the formula CH 3 CH 2 CH(CH 3)CH 2 OH. It is one of several isomers of amyl alcohol.This colorless liquid occurs naturally in trace amounts and has attracted some attention as a potential biofuel, exploiting its hydrophobic (gasoline-like) and branched structure.
Long chain oxo-alcohols are often prepared using alpha-olefins from the Shell higher olefin process, to give secondary alcohols such as isodecyl alcohol. [2] Key oxo alcohols that are sold in commerce include the following: 2-Methyl-2-butanol (2M2B) n-Butanol; 2-Ethylhexanol; 2-Propylheptanol; Isononyl alcohol; Isodecyl alcohol
In the context of butanol fuel, isobutyraldehyde is of interest as a precursor to isobutanol. E. coli as well as several other organisms has been genetically modified to produce isobutanol. α-Ketoisovalerate, derived from oxidative deamination of valine, is prone to decarboxylation to give isobutyraldehyde, which is susceptible to reduction to the alcohol: [3]

Biolipid transesterification has also been recently shown by Japanese researchers to be possible using a supercritical methanol methodology, whereby high temperature, high-pressure vessels are used to physically catalyze the biolipid/methanol reaction into fatty-acid methyl esters.
Proton transfer from the oxonium ion to a second molecule of the alcohol gives an activated complex; Protonation of one of the hydroxy groups of the activated complex gives a new oxonium ion. Loss of water from this oxonium ion and subsequent deprotonation gives the ester. A generic mechanism for an acid Fischer esterification is shown below.
This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.
