1)C2H5OH=C2H4+H2O
(условия:H2SO4.конц.)
2)C3H4=C2H2+H2
(условия:t°,Ni)
3)3C2H2=C6H6
(условия:500°, акт.уголь)
4)C6H6+CL2=C6H5CL
+HCL
(условия:80-85°,FeCL3)
5)C6H5CL+NaOH=
=C6H5OH+NaCL

C2H5OH = C2H4 + H2O при нагревании в присутствии
C2H4 + H2 =C2H6
C2 H6 + CL2 = C2H5Cl + HCL  на свету
C2H5CL + 2Na + C4H9CL = C6H14 + 2 NaOH
C6H14 = C6H6 + 4H2  300 градусов при давлении
С6H6 +C3H6 = кумол в присутствииALCL3
кумол +О2 = С6H5OH в присут Н2SО4  + CH3 -CO-CH3
C6H5OH + 3Br2 = 3 HBr + C6H2OH(Br)3
