Latest revision as of 11:24, 15 February 2025

Pentyl butyrate is an ester formed from the reaction of pentanol and butyric acid. It is commonly used in the food industry as a flavoring agent due to its fruity aroma, reminiscent of pears and apples.

Chemical Structure[edit]

Pentyl butyrate has the chemical formula C₉H₁₈O₂. It is an ester, which means it contains a carbonyl group (C=O) adjacent to an ether linkage (C-O-C). The structure consists of a butyrate group (derived from butyric acid) and a pentyl group (derived from pentanol).

Synthesis[edit]

Pentyl butyrate is synthesized through an esterification reaction. This involves the reaction of butyric acid with pentanol in the presence of an acid catalyst, such as sulfuric acid. The reaction produces pentyl butyrate and water as a byproduct.

Applications[edit]

Pentyl butyrate is primarily used in the food and beverage industry as a flavoring agent. Its fruity aroma makes it a popular choice for flavoring candies, baked goods, and beverages. It is also used in perfumes and cosmetics for its pleasant scent.

Safety and Handling[edit]

As with many chemical compounds, proper safety precautions should be taken when handling pentyl butyrate. It should be stored in a cool, dry place, away from heat and open flames. Protective equipment, such as gloves and goggles, should be worn to prevent skin and eye contact.
