2metüülpropaan
2metüülpropaan, also known as isobutane, is a hydrocarbon with the chemical formula C4H10. It is an isomer of butane, meaning it has the same molecular formula but a different structural arrangement. Isobutane is a colorless, flammable gas at standard conditions, with a boiling point of -11.7 degrees Celsius and a melting point of -159.7 degrees Celsius. It is commonly used as a propellant in aerosol cans, as a refrigerant, and as a fuel for portable stoves and lighters. Isobutane is also a byproduct of natural gas processing and petroleum refining. Due to its high flammability, it is important to handle isobutane with care and to store it in a well-ventilated area away from sources of ignition.
