Butaaniseokset

Butaaniseokset refers to mixtures containing butane. Butane, a hydrocarbon with the chemical formula C4H10, exists as two isomers: n-butane and isobutane. These isomers are colorless, flammable gases at standard temperature and pressure. Butane is commonly found in liquefied petroleum gas (LPG), which is a mixture of propane and butane, often with other hydrocarbons. The exact composition of butane mixtures can vary depending on the intended application and source.

Butane mixtures are widely used as fuel. They serve as a primary component in LPG for domestic cooking and heating, as well as for powering vehicles (autogas). In industrial settings, butane mixtures can be used as a feedstock for the petrochemical industry, for example, in the production of butadiene, a key component in synthetic rubber. They also find application as aerosol propellants and refrigerants, although these uses are subject to environmental regulations due to the gas's greenhouse effect potential. The properties of a butane mixture, such as its boiling point and vapor pressure, are influenced by the ratio of n-butane to isobutane and the presence of other components. Safety precautions are essential when handling butane mixtures due to their flammability and potential for explosion if not stored and used correctly.
