The [[chemical compound]] '''isobutyl acetate''', also known as '''2-methylpropyl ethanoate''' ([[IUPAC]] name) or '''β-methylpropyl acetate''', is a common solvent. It is produced from the [[esterification]] of [[isobutanol]] with [[acetic acid]]. It is used as a [[solvent]] for [[lacquer]] and [[nitrocellulose]]. Like many [[ester|esters]]s it has a fruity or floral smell at low concentrations and occurs naturally in [[raspberry|raspberries]], [[pear|pears]]s and other plants. At higher concentrations the odor can be unpleasant and may cause symptoms of [[central nervous system depression]] such as [[nausea]], [[Syncope (medicine)|dizziness]] and [[headache]].
 
A common method for preparing isobutyl acetate is [[Fischer esterification]], where precursors isobutyl alcohol and acetic acid are heated in the presence of a strong acid.
