A schematic for the fractional distillation of petroleum into its useful hydrocarbon components. 

Fractional distillation of petroleum separates petroleum into usable components like gasoline, kerosene, heating oil, etc. 

Bitumen extracted by the fractional distillation of petroleum is used in asphalt roads. 

Each of the smaller alkanes, from methane through Ai-pentane and isopentane, can be obtained in pure form by fractional distillation of petroleum and natural gas neopentane does not occur naturally. Above the pentanes the number of isomers of each homolog becomes so large and the boiling point differences become so small that it is no longer feasible to isolate individual, pure compounds these alkanes must be synthesized by one of the methods outlined below. 

Fractional distillation Petroleum is a complex mixture containing more than a thousand different compounds. For this reason, raw petroleum, sometimes called crude oil, has little practical use. Petroleum is much more useful to humans when it is separated into simpler components, called fractions. Separation is carried out by boiling the petroleum and collecting the fractions as they condense at different temperatures. This process is called fractional distillation or sometimes ist fractionation. Fractional distillation of petroleum is done in a fractionating tower similar to the one shown in Figure 22-18. 

Derivation Fractional distillation of petroleum, purified by rectification. 

Because most commercially available alkanes are obtained from the fractional distillation of petroleum, impurities such as the cyclic alkanes, and simple aromatic hydrocarbons such as toluene, ethyl benzene and the xylenes, may be observed in their NMR spectra. 

Hexane is extracted from petroleum. Petroleum is a complex mixture of solid, liquid, and gaseous hydrocarbons that has virtually no use itself. However, the fractional distillation of petroleum produces hundreds of individual compounds, each of which has its own important commercial and industrial applications. Fractional distillation is the process hy which petroleum is heated in tall towers. The components of petroleum hoil off at different temperatures, rise to... 

Asphalt is a product of the fractional distillation of petroleum. This fractional distillation process can occur over a long period of time in nature resulting in deposits of material known tis natural asphalts or in a short period of time in the refinery resulting in manufactured asphalts. Asphalts vary in consistency from solid materials at room temperature to materials whose...

Notice the gradual increase in boiling point as the molecular weight increases. Fractional distillation of petroleum is possible because of these differences (Section 12.2).

Fractional distillation of petroleum.The lighter, more volatile fractions are removed from higher up the column and the heavier, less volatile fractions from lower down. 

Fractional distillation of petroleum separates hydrocarbons based on their melting points (3.10)... 

Sasolinc A mixture of alkanes with chain lengths of between five and ten carbon atoms used as a fuel for internal combustion engines. It is obtained from the fractional distillation of petroleum and from cracking and reforming of hydrocarbons. See octane rating. 

Use an internet search engine (such as http //www.google. com) to locate information on fractional distillation of petroleum. List the names and boiling point ranges of six or more distillation fractions usually obtained from most crude petroleum. 

Warren carried out fractional distillations of petroleum and other complex mixtures, and observed that, as the fractions became purer, the temperature of the bath had to be brought nearer to the boiling point of the liquid in the still and required more careful regulation. 

The lower molecular mass alkanes, methane and ethane, are found principally in natural gas. Propane and butane are found dissolved in petroleum they can be extracted as gases and sold as liquefied petroleum gas (LPG). Higher alkanes are obtained by the fractional distillation of petroleum, a complex mixture of at least 500 compounds. The main petroleum fractions are listed in Table 26.4. (The liquid-vapor equilibrium principles that underlie fractional distillation were discussed on page 663.)...
