Figure  2.1  -  The  device  for  the  production  of
                 ethane (ethylene)

                      The  reaction  of  the  formation  of  ethane  is  in  two
                 stages.  At the first stage, ethyl sulfate acid is formed:





                                               t o
                      CH CH    OH +  HOSO H          CH CH    OSO H +  H  O

                                          Ethyl sulfate acid

                      ethheti second stage, when heated l sulfate acid


                           In the second stage, when heated to 170 ° С,
                 ethylsulphatic acid decomposes with the release of the ethen
                                      by the reaction:


                                          o
