Пропанол-1--->(+CuO) X1--->(+Ag2O)X2--->(Cl2)X3--->(+NH3)X4

1) Ch3-CH2-CH2OH + CuO =[ t°c ]⇒ CH3-CH2-CHO + Cu↓ + H2O
2) CH3-CH2-CHO + Ag2O =[ t°c, NH4OH ]⇒ CH3-CH2-COOH + 2Ag↓
3) CH3-CH2-COOH + Cl2 =[ Pкрасный ]⇒ CH3-CHCl-COOH + HCl↑
4) CH3-CHCl-COOH + NH3 ⇒ [CH3-CH(N⁺H3)-COOH]Cl⁻
или
CH3-CHCl-COOH + 2NH3 ⇒ CH3-CH(NH2)-COOH + NH4Cl
