CaC2 + H2O -> CaO + C2H2
3C2H2 -> C6H6
C6H6 -> C6H5SO3H (sulfonowanie)
C6H5SO3H -> C6H5OH (stapianie z wodorotlenkiem sodu)
CaC2 +H2O -> CaO +C2H2
C2H2 +H2O -> CH3CHO (katalizator - HgSO4, kwas siarkowy (VI) - reakcja Kuczerowa)
CH3CHO -> CH3COOH (utlenianie - dichromian, manganian (VII))
CH3COOH -> CH3COCl
2C6H5OH + 2CH3COCl -> 2CH3COOC6H5 + Cl2
