Ca + 2C = CaC2
CaC2 + 2H2O = C2H2 + Ca(OH)2
C2H2 + H2O = CH3CHO
CH3CHO + 2[Ag(NH3)2]OH = CH3COOH + 2Ag + 2H2O + 4NH3
CH3COOH + Cl2 = ClCH2COOH + HCl
ClCH2COOH + 2NH3 = NH2CH2COOH + NH4Cl
Ca + 2C = CaC2
CaC2 + 2H2O = C2H2 + Ca(OH)2
C2H2 + H2O = CH3CHO
CH3CHO + 2[Ag(NH3)2]OH = CH3COOH + 2Ag + 2H2O + 4NH3
CH3COOH + Cl2 = ClCH2COOH + HCl
ClCH2COOH + 2NH3 = NH2CH2COOH + NH4Cl
