Uses
Butanol (CAS NO.35296-72-1) is used in producing the butyl acetate, the phthalic acid dibutyl ester and the phosphoric acid class plasticizer, and it is also used in producing the melamine resin, the acrylic acid, the epoxy varnish. It is used as the chromatograph analytical reagent, it is also used in the organic synthesis.
Specification
Butanol (CAS NO.35296-72-1)or butyl alcohol can refer to any of the four isomeric alcohols of formula C4H9OH: n-Butanol ; Isobutanol ; sec-Butanol ; tert-Butanol . It may be used as a fuel in an internal combustion engine. It is more similar to gasoline than it is to ethanol and has been demonstrated to work in some vehicles designed for use with gasoline without any modification.
Butanol from biomass is called biobutanol and can be used in unmodified gasoline engines . Its better tolerates water contamination and is less corrosive than ethanol and more suitable for distribution through existing pipelines for gasoline. As an advantage, butanol production from biomass could be more efficient than ethanol or methanol routes. Currently no production vehicle is known to be approved by the manufacturer for use with 100% butanol.
