1) CaO + 3C → CaC2 + CO (substitution reaction);
2) CaC2 + 2H2O → C2H2 + Ca (OH) 2 (exchange reaction);
3) 3C2H2 → C6H6 (trimerization reaction, under the influence of temperature);
4) C6H6 + HNO3 → C6H5NO2 + H2O (substitution reaction; occurs upon heating, and the addition of sulfuric acid H2SO4).
