ButenesButane

Butenes-Butane is a combination of two types of hydrocarbons known as butenes and butane. Butenes are a group of unsaturated aliphatic hydrocarbons with the general formula C4H8. They are found in the petroleum system as a product of the straight-run gasoline fraction.

Butane, on the other hand, is a saturated hydrocarbon with the same general formula as butenes but with the double bonds reduced to single bonds. It is often used as a fuel or refrigerant due to its low boiling point. Butane can be found as a separate component or as a blend with butenes in some petroleum products.

The physical properties of a butenes-butane mixture can vary depending on the relative proportions of the two components. It is generally a clear, colorless liquid with a characteristic odor. When mixed with air, it can be highly flammable. Handling butenes-butane mixtures requires caution, as they can ignite explosively if not properly vented or stored.

While butenes and butane occur naturally, mixtures of the two are often produced through the cracking of heavier hydrocarbons in a petroleum refinery. This process involves breaking down higher molecular weight compounds into smaller, lighter components, which are often a mixture of butenes and butane. As a result, butenes-butane is widely used in various industrial applications, including as a feedstock for the production of other chemicals and products.
