Natural gasoline

Gasoline is a highly flammable, mobile liquid with a characteristic odor. A complex mixture of volatile hydrocarbons (paraffins, cycloparaffins, and aromatics). Physical property values may vary depending on grade. The Odor Threshold is 0.25 ppm.

Highly flammable, dangerous fire, and explosion risk. Eye and upper respiratory tract irritant, and central nervous system impairment. Possible carcinogen. The distillation ranges of gasoline are specified for the particular application, mainly the reciprocating, spark ignition, and internal combustion engines. To serve specific purposes, various functional additives are blended into gasolines. These consist of antiknock fluids, antioxidants, metal deactivators, corrosion inhibitors, anti-icing agents, preignition preventors, upper cylinder lubricants, dyes, and decolorizers (161). Probably the most critical property is the octane number, supplied with high octane hydrocarbons and lead compounds. The major components are primarily paraffins, olefins, naphthenes, and aromatics, and more recently 10–40% ethyl alcohol. The distillation from initial to final boiling point ranges from about 32 to 225℃(90 to 437°F), and the explosive limits are 1.31–6.0%.
