description
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.

Uses
Isobutyl Acetate can be used as organic solvent, the solvent of nitrocellulose and lacquer, extraction agent, dehydrating agents. It can also be applied to collodion, nitrocellulose, varnishes, leather, pharmaceuticals, plastics and perfume industry. Solvent; flavoring Isobutyl acetate is used as a solvent and as aflavoring agent. Isobutyl Acetate is a flavoring agent that is a clear colorless liquid
with a fruity odor resembling banana when diluted. it is soluble in
alcohol, propylene glycol, most fixed oils, and mineral oil, and
slightly soluble in water. it is obtained by synthesis.
-
Production method
It can be obtained via the esterfication between iso-butanol and acetic anhydride in the presence of sulfuric acid. Mix the acetic anhydride and iso-butanol solution followed by adding drop wise of sulfuric acid. Heat for reflux of 5-6 h after a bit cooling, wash the refluxed liquid with water for 2-3 times. Use sodium carbonate for neutralizing with sodium carbonate, wash with water until neutralized, dry over calcium chloride with vacuum distillation in oil bath to derive the finished products.

Description
Isobutyl acetate has a fruity (currant-pear), floral (hyacinth-rose)
odor and a characteristic ether-like, slightly bitter flavor. May be
prepared by direct esterification of isobutyl alcohol with acetic
acid.

Physical properties
Colorless liquid with a fruity odor. Experimentally determined detection and recognition odor
threshold concentrations were 1.7 mg/m3 (360 ppbv) and 2.4 mg/m3 (510 ppbv), respectively
(Hellman and Small, 1974).
