How many vehicles use propane in 2007?
In 2007, approximately 13 million vehicles worldwide use autogas. The advantage of propane in cars is its liquid state at a moderate pressure. This allows fast refill times, affordable fuel cylinder construction, and price ranges typically just over half that of gasoline.
What is the enthalpy of propane gas?
The enthalpy of combustion of propane gas where products do not return to standard state, for example where the hot gases including water vapor exit a chimney, (known as lower heating value) is −2043.455 kJ/mol. The lower heat value is the amount of heat available from burning the substance where the combustion products are vented to the atmosphere; for example, the heat from a fireplace when the flue is open.
What is the chemical name for propane?

What is propane used for?
Propane is widely used for space and water heating, cooking, and as a fuel for engine applications such as forklifts, farm irrigation engines, fleet vehicles, and buses; but, due to new technological advances, its applications are increasingly growing. The propane is known as propane autogas when used as vehicle fuel.
Why does propane burn?
Propane burns in the presence of an excess amount of oxygen to produce carbon dioxide and water. When too much or too less oxygen is available for the combustion reaction, incomplete combustion takes place, forming soot (carbon) and/or carbon monoxide.

Overview
Propane is a three-carbon alkane with the molecular formula C3H8. It is a gas at standard temperature and pressure, but compressible to a transportable liquid. A by-product of natural gas processing and petroleum refining, it is commonly used as a fuel in domestic and industrial applications and in low-emissions public transportation. Discovered in 1857 by the French chemist Marcellin Bert…

Properties and reactions
Propane is a colorless, odorless gas. At normal pressure it liquifies below its boiling point at −42 °C and solidifies below its melting point at −187.7 °C. Propane crystallizes in the space group P21/n. The low spacefilling of 58.5% (at 90 K), due to the bad stacking properties of the molecule, is the reason for the particularly low melting point.
Uses
Propane is a popular choice for barbecues and portable stoves because the low boiling point of −42 °C (−44 °F) makes it vaporize as soon as it is released from its pressurized container. Therefore, no carburetor or other vaporizing device is required; a simple metering nozzle suffices.

Purity
The North American standard grade of automotive-use propane is rated HD-5 (Heavy Duty 5%). HD-5 grade has a maximum of 5 percent butane, but propane sold in Europe has a maximum allowable amount of butane of 30 percent, meaning it is not the same fuel as HD-5. The LPG used as auto fuel and cooking gas in Asia and Australia also has very high butane content.

Comparison with natural gas
Propane is bought and stored in a liquid form, LPG. It can spill. It can easily be stored in a relatively small space.
By comparison compressed natural gas (CNG) cannot be liquefied by compression at normal temperatures, as these are well above its critical temperature. As a gas, very high pressure is required to store useful quantities. This poses the hazard that, in an accident, just as with any co…
Hazards
Propane is a simple asphyxiant. Unlike natural gas, propane is denser than air. It may accumulate in low spaces and near the floor. When abused as an inhalant, it may cause hypoxia (lack of oxygen), pneumonia, cardiac failure or cardiac arrest. Propane has low toxicity since it is not readily absorbed and is not biologically active. Commonly stored under pressure at room temperature, propane and its mixtures will flash evaporateat atmospheric pressure and cool well below the fre…

Propyne and Propene Can Be Distinguished by
- Propyne is terminal alkyne so it gives white precipitate with ammonical silver nitrate solution but alkene does not. Thus propene and propyne can be distinguished by ammonical silver nitrate solution. Terminal alkynes forms silver salt with Tollen’s reagent while alkene does not react with Tollen’s reagent. Therefore, Tollen’s reagent can be used to distinguish a terminal alkyne like pro…
