Gasoline is a petroleum distillate product at a temperature which hovers between 60 and 100 ° C. From a liter of oil becomes gasoline, only 10% after the first simple distillation. To this we must add that using the heavier fractions (heavy fuel oil and distillation residues) may be obtained by smaller molecules suitable for use as gasoline, thanks to a treatment that cracked through which higher molecular weight hydrocarbons are fragmented in the presence of a catalyst.
Use gasoline as a fuel requires that it have certain characteristics: volatility
Adequate (enough for a quick start the engine)
Good antiknock capacity (capacity not ignite at the push of the piston)
latter figure is measured with the famous " octane number (NO). This is a benchmark index to a scale in which the pure isooctane is equal to 100 (just detonating) and normal-heptane is equal to 0 (very detonating). To improve anti-knock properties of gasoline in the past has made use of additives consisting of lead compounds whose use for the polluting effects, led to the birth of the so-called green gasoline, low levels of lead. In this, the previous detonating agent (tetraethyl lead) is Methyl Tertiary Butyl Ether replaced by, or MTBE.
Gasoline is extremely flammable and therefore dangerous to its high flammability due to a simple spark. Description
