Propane
Propane is a three-carbon alkane with the chemical formula C3H8.
Propane is a three-carbon alkane (C3H8) that serves as a common fuel, often sold as part of liquefied petroleum gas (LPG). It is a colourless gas at room temperature but can be compressed into a liquid for storage and transport.
What it is
Propane is a saturated hydrocarbon in the alkane family, with the molecular formula C3H8 and the structure CH3CH2CH3. It is the third member of the alkane series after methane and ethane, and is colourless and odorless in its pure form.
Key details
Propane is produced during natural gas processing and petroleum refining. It boils at −42.1 °C and has a molar mass of 44.10 g/mol. Because it is easily liquefied under pressure, it is commonly stored in pressurized containers for use as a fuel in heating, cooking, and industrial equipment.
Why it matters
Propane is widely used across Canada for home heating, cooking, agriculture, and industrial applications. An odorant is typically added before sale so leaks can be detected more easily, making it safer for everyday use.
In short
- Propane is a three-carbon alkane (C3H8) and a major component of LPG.
- It is a gas at standard conditions but liquefies under pressure.
- Commonly sourced from natural gas and petroleum refining.
- Used as a fuel for heating, cooking, and industrial purposes.
Propane is used across Canada for home heating, cooking, agriculture, and industrial applications, and Canadian consumers often encounter it as bottled fuel or as part of LPG supply chains.
