AL4C3-CH4-CH3CL-C2H6-C2H5OH-H20

1) Al4C3 + 12H2O -------> 3CH4 + 4Al(OH)3

                         Свет,t

2) CH4 + Cl2 ---------> CH3Cl + HCl

                                              t

3) CH3Cl + 2Na + CH3Cl --------> C2H6 + 2NaCl

               Ni,t

4) C2H6 ----- > C2H4 + H2

    C2H4 + H2O ------ > C2H5OH

5) C2H5OH + 3O2 ------ > 2CO2 + 3H2O
