                    Natural sources of hydrocarbons and their
                                       processing

                      Purpose:
                      To  know  the  nature  and  composition  of  natural
                 sources of hydrocarbons: natural and associated petroleum
                 gas, petroleum, coal.
                      Own  information  on  the  processing  of  natural
                 hydrocarbons  and  their  use:  thermal  cracking,  catalytic
                 cracking, pyrolysis.
                       Be  able  to  experimentally  determine  the  fractional
                 composition of oil.

                                    Reagents and equipment:
                      Oil, Wurtz's flask, Wurtz's nozzle, direct refrigerator,
                 allonge, receivers, thermometer at 250 ° C, "hot water" (thin
                 glass  capillaries),  electric  heating  device,  technical  scales,
                 arrmeter.
                                      The theoretical part
                      Oil is a mixture of organic compounds, most of which
                 are hydrocarbons. All the oils contain alkanes, cycloalkanes
                 (naphthenes),  arenes,  however,  their  quantitative  ratios  in
                 different  oils  are  unequal.    Distillation  of  oil,  that  is,  its
                 separation into a fraction depending on the boiling point, is
