Butyl Acetate

 

butyl ester of acetic acid. Three structural isomers are known, of which two are widespread: normal butyl acetate, CH3(CH2)3OCOCH3, and isobutyl acetate, (CH3)2CHCH2OCOCH3. They are colorless liquids with a characteristic ester odor and boiling points of 126.1° C and 118.0° C, respectively. Butyl acetates are poorly soluble in water. They are miscible with organic solvents and vegetable oils; they also possess all the characteristics of esters. Butyl acetates are obtained by heating the corresponding alcohol with acetic acid in the presence of H2S04. They are good solvents of chlorinated rubber, nitrocellulose, Glyptal resins, and other film-forming substances widely used in the manufacture of paints and varnishes.
