Butyric acid pentyl ester is an ester of butyric acid and 1-pentanol .
Occurrence
Butyric acid pentyl ester is one of the so-called fruit esters and occurs in apples.
Extraction and presentation
Pentyl butyrate can be prepared by esterification of butanoic acid and 1-pentanol with sulfuric acid are recovered as the catalyst.
use
Butyric acid pentyl ester is often added to foods that taste like apricots or contain apricots, but also to cigarettes as a flavoring substance . It is also used in the paint industry.
