CaO + 3C => CaC2 + CO
CaC2 + 2H2O => Ca(OH)2 + C2H2 (axetilen)
3C2H2 => (cacbon hoạt tính, 600oC) C6H6
C6H6 + Br2 => HBr + C6H5Br (brom benzen)
C2H2 + H2 => (to,Pd) C2H4
C2H4 + H2O => (140oC, H2SO4đ) C2H5OH (rượu etylic)
C2H5OH + O2 => (men giấm) H2O + CH3COOH (axit axetic)
CH3COOH + C2H5OH => (to,H2SO4đ, pứ hai chiều) H2O + CH3COOC2H5 (etyl axetat)
n -(CH2-CH2)- => (to,xt,P) -(CH2-CH2)-n
CaO + C -to-> CaC2 + CO
CaC2 + H2O --> Ca(OH)2 + C2H2( axetilen)
C2H2 -bột C,to-> C6H6
C6H6 + Br2 -bột Fe,to-> C6H5Br (brombenzen) + HBr
C2H2 + H2 -Pd,to-> C2H4
C2H4 + H2O-axit-> C2H5OH (rượu etylic)
nCH2=CH2 -to,p,xt-> (-CH2-CH2-)n (polietilen)
C2H5OH + O2-mg-> CH3COOH (axit axetic) +H2O
C2H5OH + CH3COOH <-H2SO4đ,to-> CH3COOC2H5 (etyl axetat) + H2O
