Butane : Description and use


Butane is a saturated hydrocarbon of the alkane family. It comes in two isomeric forms, n-butane and isobutane or 2-methylpropane. Residual quantities of 1,3-butadiene may be present in butane. The concentration of 1,3-butadiene is variable and depends on the quality of the butane produced. The concentration of residual 1,3-butadiene in butane is generally 0.1% p/p or less. However, residual quantities exceeding 1.0% p/p have been detected.
It is a liquefied compressed gas that is odourless and colourless.

Flammability: Butane is a highly flammable gas. It ignites quickly in the air if exposed to a static charge, a spark, an open flame or any other source of ignition or combustion.
Explosiveness: Butane forms an explosive mixture with air when it is found in concentrations between 1.8 and 8.5%.

  • Solvent for paints, varnishes, natural or synthetic resins.
  • Solvent used in cleaning and degreasing products and brake fluids. Solvent for coating textiles.
  • Solvent used for extracting and purifying the following products: vegetable oils, gums, waxes, perfumes, alkaloids, antibiotics, hormones, vitamins, etc.
  • An intermediate in organic synthesis particularly for manufacturing butyl esters used as solvents.
