What is 1 methylpropane


  2-methyl-1-propanol (also i-butanol or isobutanol) is an aliphatic hydrocarbon and belongs to the group of alkanols, which in turn belong to the alcohols.

Extraction and presentation

Like 1-butanol, 2-methyl-1-propanol is also obtained by hydroformylating propene. In contrast to the production of 1-butanol, one continues to work with the other reaction product and hydrogenates it:

Propene reacts with carbon monoxide and hydrogen to form butanal and 2-methylpropanal.
The resulting 2-methylpropanal reacts with hydrogen to form 2-methyl-1-propanol.


Physical Properties

2-methyl-1-propanol is a colorless liquid that smells sweet. Like all butanols, 2-methyl-1-propanol is also flammable. You can mix 2-methyl-1-propanol with all common organic solvents such as ethers, glycol, alcohols, ketones and aldehydes, but it is only partially soluble in water.

Chemical properties


Possible reactions of 2-methyl-1-propanol are esterification to an ester or dehydrogenation to an aldehyde.

2-Methyl-1-propanol reacts with ethanoic acid to form ethanoic acid 2-methyl-propyl ester and water.
2-methyl-1-propanol reacts to form 2-methylpropanal and hydrogen.


2-Methyl-1-propanol is used in derivatives as a solvent, mainly in the paint industry. It improves the properties of the paints.
