1. Al4C3 + 12H2O → 3CH4 + 4Al(OH)3

CH4 (1500)→ CH≡CH

3CH≡CH → C6H6(бензол)

C6H6 + Br2 (AlBr3)→ C6H5Br + HBr

C6H5Br + NH3 → [C6H5NH3]Br

2. Al4C3 + 12H2O → 3CH4 + 4Al(OH)3

CH4 (1500)→ CH≡CH

CH≡CH + H2O → CH3-COH

3CH3-COH + 2KMnO4 → 2CH3-COOK + 2MnO2 + CH3-COOH + H2O

CH3-COOK + KOH(тв.) → CH4 + K2CO3
