Make an equation: calcium oxide-calcium carbide-acetylene-ethanal-ethanol-ethylene.

Make an equation: calcium oxide-calcium carbide-acetylene-ethanal-ethanol-ethylene. Write the reaction equations and indicate the conditions of their occurrence

CaO → CaC2 → C2H2 → CH3CHO → C2H5OH → C2H4

1) CaO + 3C → CaC2 + CO (at temperature);

2) CaC2 + 2H2O → Ca (OH) 2 ↓ + C2H2;

3) C2H2 + H2O → CH3CHO (catalyst – mercury (II) salt in acidic medium; Kucherov reaction);

4) CH3CHO + H2 → C2H5OH (catalyst – Ni, the reaction proceeds at temperature);

5) C2H5OH → C2H4 + H2O (the reaction proceeds at a temperature of 350-360 ° C and catalyst Al2O3).
