a) CaC2 + 2H2O --> Ca(OH)2 + C2H2
C2H2 + H2 -Ni-> C2H4
C2H4 + H2O --> C2H5OH
C2H5OH + O2 -mg-> CH3COOH + H2O
CH3COOH + C2H5OH <-H2SO4đ,to-> CH3COOC2H5 + H2O
b) (-C6H10O5-)n + nH2O -axit-> nC6H12O6
C6H12O6 -mr-> 2C2H5OH + 2CO2
C2H5OH + O2 -mg-> CH3COOH + H2O
CH3COOH + C2H5OH <-H2SO4đ,to-> CH3COOC2H5 + H2O
CH3COOC2H5 + NaOH -to-> CH3COONa + C2H5OH

a/ CaC2 + 2H2O => Ca(OH)2 + C2H2
C2H2 + H2 => (Pd,to) C2H4
C2H4 + H2O => (140oC,H2SO4đ) C2H5OH
C2H5OH + O2 => (men giấm) CH3COOH + H2O
CH3COOH + C2H5OH => (H2SO4đ,to,pứ hai chiều) CH3COOC2H5 + H2O: pứ este hóa
