n-Butyl acetate, also known as butyl ethanoate, is an organic compound commonly used as a solvent in the production of lacquers and other products. It is also used as a synthetic fruit flavoring in foods such as candy, ice cream, cheeses, and baked goods. Butyl acetate is found in many types of fruit, where along with other chemicals it imparts characteristic flavors. Apples, especially of the Red Delicious variety, are flavored in part by this chemical. It is a colourless flammable liquid with a sweet smell of banana.
The other three isomers of butyl acetate are: isobutyl acetate, tert-butyl acetate, and sec-butyl acetate.

Production
Butyl acetates are commonly manufactured by the esterification of a butanol isomer and acetic acid with the catalytic presence of sulfuric acid under reflux conditions. 1
Health Concern
Eye And skin contact - Liquid contact with the eye may cause moderate eye irritation, Vapor exposure may cause eye irritation, experienced as mild discomfort and redness, Brief contact is essentially non-irritating to skin, however prolonged contact may cause severe skin irritation with local redness and discomfort. Skin exposure may cause drying and flaking of the skin. Prolonged skin contact is unlikely to result in absorption of harmful amounts. Allergic skin reactions have not been reported in animals or humans following repeated contact with n-butyl acetate.
Inhalation - Excessive inhalation exposure may cause irritation to the upper respiratory tract(nose and throat) and lungs. Symtoms of excessive exposure may be anesthetic or narcotic effects, and dizziness and drowsiness may be observed.
Ingestion - n Butyl acetate has very low toxicty if swallowed. Harmful effects are not anticipated from swallowing small amounts. However, aspiration into the lungs may occur during ingestion or vomiting, causing lung cancer damage or even death due to chemical pneumonia. Do not induce vomiting.
Other - n-Butyl acetate has been toxic to the fetus in lab animals at it doses that are not toxic to the mother. Data in laboratory animals suggest that the material does not affect reproduction or result in birth defects. In vitro genetic toxicity studies were negative.2
