CuCO3->CaC2->C2H2->CH3-CH2-OH->CH3-CH2-Cl->CH2=CH2
1) CaCO3+3C=(t 2000, сплав)CaC2+CO+CO2
2)CaC2+2H2O=Ca(OH)2+C2H2
3)C2H2+H2=(t,Ni)C2H4
4)C2H4+H2O=C2H5OH
5)C2H5OH+Hcl(к)=C2H5Cl+H2O
6)C2H5CL+NaOH(спирт)=C2H4+NaCl+H2O
CaCO₃ -> CaC₂ -> C₂H₂ -> CH₃-CH₂-OH -> CH₃-CH₂-Cl -> CH₂=CH₂
1)
2) CaC₂ +2 H₂O = Ca(OH)₂ + HC≡CH
3) HC≡CH + H₂ ->(при t, катал.)-> H₂C=CH₂
H₂C=CH₂ + H₂O -> H₃C-CH₂OH
4)C₂H₅OH + HCl -> C₂H₅Cl + H₂O
5)
