Propane is an organic chemical compound, normally a gas at standard conditions, but compressible to a transportable liquid. It has the chemical formula C3H8.

PropertiesEdit

ChemicalEdit

In the presence of excess oxygen, propane burns to form water and carbon dioxide, releasing large amounts of heat.

C3H8 + 5 O2 → 3 CO2 + 4 H2O + heat

PhysicalEdit

Propane is a colorless, odorless gas at standard conditions. It boils at around −42°C and freezes at −187.7 °C.

AvailabilityEdit

Propane is available in LPG tanks, usually mixed with other alkanes or alkenes and thiols. This combination is generally used for gas grills.

PreparationEdit

Propane can be prepared by heating a mixture of sodium butyrate and sodium hydroxide.

ProjectsEdit

  • Make propene
  • Make nitromethane
  • Halopropanes

HandlingEdit

SafetyEdit

Propane is nontoxic, but may pose asphyxiation risk through oxygen deprivation if inhaled. When compressed propane is released, the gas expands and cools, presenting a frostbite hazard.

StorageEdit

Liquified propane should be stored away from heat sources.

DisposalEdit

Propane can be burned safely, as it will not release toxic byproducts.
