Properties

Pentane has three isomers: n-pentane, methylbutane, dimethylpropane. N-pentane is the most common one and is the one most reffered to. Pentane has five carbon atoms and twelve hydrogen atoms thus making its chemical formula C5H12. Pentanes physical stae is a clear, colorless liquid with a gasoline like odor. Some say that its odor is quite pleasant and mild. The Vapor pressure of Pentane is 514 milimeters of Mercury at 25 degrees Celcius. Pentanes boiling point is 36 degrees Celcius and its freezing and melting point is -130 degrees Celcius.

Occurrences

Description

Pentane can come from a few different places. First it can come from natural gasses but when released to the atmosphere its most likely in a small amount. Pentane can also be found when using products and burning it off, and even can be found in industrial manufacturing.

Uses

Pentanes main use is in petrol fuel for some vehicles. Though as you may not know it is also used in the chemical industry as a solvent to produce other chemicals. Pentane has been used in filling plastic foams replacing more harmful chemicals such as hydofluorocarbons and Hydrochlorofluorocarbons which hurt the ozone layer.

Affects

Description

Pentane is a fairly harmful material to the environment. It is highly unlikely that pentane pollution affects the global environment, but instead it can kill crops and wildlife. The wildlife killed through pentane is mostly aquatic but this does not happen often because of the small amounts of pentane being released at one particular time. Pentane affects humans too, and in some cases quite severely. In high ammounts pentane can lead to a coma or death. There are two to three ways of being affected by pentane: ingestion, inhalation or if it absorbs through the skin. Inhalation can cause irritation of the respiratory tract, drowsiness, headache, dizziness, a burning sensation in the chest, and even unconsciousness. Ingestion can cause irritation of the digestive tract, nausea, vomiting and diarrhoea. When absorbed in the skin it can cause skin irritation and dermatitis. Contact with the eye can lead to pink eye or conjunctivits, irritation and damage to the cornea. If swallowed it can vaporize and lead to aspiration into the lungs and health effects similar to those for inhalation.
