WebThe esters include ethyl acetate, n-butyl acetate, isobutyl acetate, and propyl acetate. They are typically produced by catalyzed reaction from acetic acid and the corresponding alcohol: CH 3 COO−H + HO−R → CH 3 COO−R + H 2 O, R = general alkyl group. For example, acetic acid and ethanol gives ethyl acetate and water. http://mason.gmu.edu/~spatanar/GC%20acetates%20lab.pdf
