Solubility: Micro-soluble in water, soluble in ethanol, ethyl ether.

Main purpose: For organic synthesis. For the production of ethylene and propylene raw materials or solvents in the oil refining industry; Propane, butane and ethane a mixture of a small amount of liquefied fuel can be used as civilian, or liquefied petroleum gas.

Health hazards: A simple suffocation of the goods and narcotic effect. Short-term contact with people one percent propane, do not cause symptoms; Below 10% concentration, caused only mild dizziness; Contact with high concentrations can occur when anesthesia, loss of consciousness; Very high concentration can be caused by suffocation.

Blasting danger: Flammable materials.

Hazardous characteristics: Flammable gas. Mixed with the air can form explosive mixtures, the case of a fire burning heat and the risk of explosion. Oxidant contact with the violent reaction. Gas heavier than air, can lower the spread to a distant land, event will fire back fire burning.
