Ответ:

2CaCO3+3C→2CaC2+3CO2

CaC2+2H2O→Ca(OH)2+C2H2

C2H2+H2→C2H4 (t,Pt)

C2H4+HCl→C2H5Cl

2C2H5Cl+2Na→2NaCl+C4H10 (t)

C4H10→C4H8+H2 (t,Ni)

C4H8+H2O→C4H9OH (t, H2SO4)

C4H9OH+CuO→C3H7CHO+Cu+H2O (t)

C3H7CHO+H2→C4H9OH (t, Ni)

C4H9OH→C4H8+H2O (t, H2SO4)

C4H8→C4H6+H2 (t, Ni)

2C4H6+11O2→8CO2+6H2O (t)
