Description

Propane, C3H8 — organic substance of a class of alkanes. Contains in natural gas, it is formed when cracking oil products, at division of associated oil gas, "fat" natural gas as collateral production at various chemical reactions. As the representative of hydrocarbonic gases pozharo-is also explosive, malotoksichen, has no smell, possesses weak narcotic properties.

Flavourless colourless gas. We will dissolve in water very little. Boiling point −42,1 °C. Freezing point −188 °C. Forms with air explosive mixes at concentration of vapors from 2,1 to 9,5%. Temperature of spontaneous ignition of propane in air with a pressure of 0,1 MPas (760 mm of mercury.) makes 466 °C. Critical temperature of propane Tkr = 370 K, critical pressure Rkr = 4,27 MPas, critical specific volume of Vkp = 0,0444 m3/kg. Density of the compressed and liquefied propane at 298 K — 0,493 kg/l.
Density of a liquid phase = 510 kg/m3.
Density of a gas phase under normal conditions = 2,019 kg/m3.
Density of a gas phase at a temperature at 15 °C = 1,900 kg/m3.
Chemical properties:
Are similar to properties of other representatives of a number of alkanes (dehydrogenation, chlorination etc.)
Application:
Fuel
Propane cylinder by a utility truck
When performing gas-flame works at plants and the enterprises:
in procuring production;
for cutting of scrap metal;
for welding of an irresponsible metalwork.
During the roofing works.
For heating of production rooms in construction.
For heating of production rooms (on farms, poultry farms, in greenhouses).
For gas stoves, water-heating columns in the food industry.
In life
when cooking in house and marching conditions;
for heating of water;
for seasonal heating of the remote rooms — private houses, hotels, farms;
for welding of pipes, greenhouses, garages and other economic designs with use of gas-welding posts.
Recently it is widely used as automobile fuel as cheaper and ecologically more safely than gasoline.
It is stored and transported in metal cylinders of bright red color (not to confuse to brown cylinders for helium)

Chemistry and food industry
In chemical industry it is used when receiving monomers for production of polypropylene.
Is initial raw materials for production of solvents.
It is used as propellant.
In the food industry propane is registered as a food additive of E944.
