Isobutyl acetate Usage And Synthesis
  • descriptionIsobutyl 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.

  • Chemical PropertiesIt is a water-white liquid with soft fruit ester flavor. It is miscible with a variety of organic solvents such as alcohols, ethers and hydrocarbons.
  • UsesIsobutyl 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.
  • Content AnalysisIt can be determined according to the method 1 in ester assay (OT-18). The amount of the sample for taking is 1g. The equivalency factor (e) for the calculation can be taken as 58.08. Alternatively, people can apply non-polar column method via gas chromatography (GT-10-4) for the determination.

  • ToxicityLD50: 13400 mg/kg (rat, oral).
    GRAS (FEMA).
  • Limited useFEMA (mg/kg): soft drinks: 11; cold drink: 16; Confectionery: 36; Bakery: 35; pudding class: 170; gum: 860; coating: 5.5.
    Take appropriate amount as limit (FDA§172.515,2000).
  • Production methodIt 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.
  • Chemical PropertiesCLEAR LIQUID
  • DefinitionChEBI: The acetate ester of isobutanol.
  • General DescriptionA clear colorless liquid with a fruity odor. Flash point 64°F. Less dense than water (6.2 lb / gal) and insoluble in water. Vapors are heavier than air .
  • Air & Water ReactionsHighly flammable. Insoluble in water.
  • Reactivity ProfileIsobutyl acetate reacts exothermically with acids to give alcohols and other acids. May react sufficiently exothermically with strong oxidizing acids to ignite the reaction products. Reactions with bases also generate heat. Combination with strong reducing agents (alkali metals and hydrides) generates flammable hydrogen.
  • Health HazardVapors may irritate upper respiratory tract and cause nausea, vomiting, dizziness and loss of consciousness. Liquid irritates eyes and may irritate skin.
  • Fire HazardHIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water.
