Abstract
Firstly, under the temperature of 85 ℃ , taking t N, N-dimethylformamide as catalyst, the title concerned compound was synthesized from phosphorus trichloride and dichloroactic acid with yield of 60.8/. And then, using hydroxide sodium as acid-tied agent, trichloromethane as solvent, dichloroacetyl, ethanolamine and butanone as starting materials, the herbicide safener 3-dichloracetyl-2-methyl-2-ethyl-1,3-oxazolidine was synthesized with yield of 78.6/. Lastly, its structure was characterized by means of UV, IR, 1H-NMR and GC— MS. Results showed that the structure of 3-dichloracetyl-2-methyl-2-ethyl-1,3-oxazolidine was confirmed.
