Petroleum refining is the process of separating the many compounds present in crude petroleum. This process is called fractional distillation where the crude oil is heated; the various of the compounds boil at different temperatures and change to gases;

however, gasoline is one of the major products made by oil companies. Rather than continually distilling large quantities of crude oil, oil companies chemically process some other fractions from the distillation column to make gasoline; ... In the next section, we'll look at how we chemically process one fraction into another.

Fractional distillation of crude oil is the first step in the production of many of the materials we have come to rely on in modern life. Almost all our fossil fuelscome from this process. ... After the Fractional Distillation Of Crude Oil ... The boiling point of a Hydrocarbon fraction, which is the temperature at which...

About 10% of the product of the distillation of crude oil is a fraction known as straight-run gasoline, which served as a satisfactory fuel during the early days of the internal combustion engine. As the automobile engine developed, it was made more powerful by increasing the compression ratio.

If the original is a mixture of liquids, each boils off at its boiling point and is cooled in turn to form a fraction of the original mixture. This is known as a fractional distillation. Crude oil, a mixture of many substances including a number of liquids, is refined in this way.

This experiment simulates the industrial fractional distillation of crude oil in the laboratory ... 3 It is important to try the experiment beforehand. It may be necessary to add an additional low boiling point fraction – eg cyclohexane – to obtain something below 70 °C.
