Acetic acid sec -butyl ester, and sec -butyl acetate or 1- Methylpropylethanoat (IUPAC), is a clear, colorless solvent with fruchtartigem odor. Acetic acid sec -butyl ester is an ester of acetic acid and 2 -butanol.

It should be noted that in this article only from the racemate ( ±) -acetic acid sec -butyl ester are talking about. There is also the pure enantiomers ( ) -acetic acid sec -butyl ester and (-) -acetic acid sec -butyl ester, and the structural isomers of n-butyl acetate, isobutyl acetate and acetic acid tert-butyl ester.

Properties

Acetic acid sec -butyl ester is a colorless liquid with fruchtartigem odor. The melting temperature is -99 ° C, while the boiling point is 112 ° C.

The compound forms flammable vapor - air mixtures. It has a flash point of 16 ° C. The lower explosive limit (LEL) is about 1.3 % by volume (63 g/m3). The ignition temperature is 410 ° C. The fabric falls within the temperature class T2.

Production

Acetic acid sec -butyl ester can be prepared as a catalyst, by the esterification of acetic acid with sulfuric acid, and 2-butanol.

Use

Acetic acid sec -butyl ester is a common paint solvent, since it due to the relatively high boiling point allows for a slow drying. Furthermore, it is also used in chemical laboratories as a solvent.
