| Abstract: | The target compound was synthesized with 2,4-dichlorobenzaldehyde oxime and chloroacetic acid in acetonitrile.The influence of the factors of solvent,molar ratio of the reagent,and the reaction time on the product yield was discussed.The experimental results showed that when the molar ratio of n（2,4-dichlorobenzaldehyde oxime）：n（chloroacetic acid）：n（sodium hydroxide）was 1： 2：3.1,and the reaction time was 4 h,the yield can reach 62.8%.2,4-dichlorobenzylideneaminooxy acetic acid was characterized by melting point,IR,1H NMR and UV-vis spectroscopy. |
