Isobutyl acetate, also known as n-propyl acetate, is the esterfication product between acetic acid and 2-butanol. It is a water-white liquid with flavor of soft fruit ester. It is slightly soluble in water, miscible with ethanol, ethyl ether as well as many other kinds of organic solvent including alcohol, ether and hydrocarbon. It can be mainly used as the diluent of nitro-lacquer and perchlorethylene paint and the solvents of nitrocellulose and lacquer as well as the substitution solvent of butyl acetate and methyl isobutyl ketone. It can also be used as a component of the flavoring agent. It can also be used as the diluent of plastic printing paste and the extraction agent in the pharmaceutical industry.
Sec-butyl acetate has excellent capability of dissolving many substances. It can be industrially applied as the solvent for manufacturing of nitrocellulose paint, acrylic paint, polyurethane paint, etc., these paints can also be used as an aircraft wing paint, artificial leather coatings and automotive coatings. Its dissolving capability is similar as n-butyl acetate and isobutyl acetate. In the coating formulation, it can be widely adopted for substitution of n-butyl acetate and isobutyl acetate. In metallic paints, people can apply butyl acetate to dissolve the cellulose acetate butyrate to obtain 15% to 20% solution.
