摘　　要：首先以三氯化磷、二氯乙酸为原料,N,N-二甲基甲酰胺作催化剂,控制温度85℃,合成了重要反应原料二氯乙酰氯,产率60.8/。然后用氢氧化钠作缚酸剂、三氯甲烷为溶剂,利用二氯乙酰氯、乙醇胺和丁酮为原料,反应温度-4～4℃,搅拌1h,一锅法合成了除草剂安全剂3-二氯乙酰基-2-甲基-2-乙基-1,3-噁唑烷,产率78.6/。最后,对合成的化合物结构应用紫外光谱、红外光谱、核磁共振谱和气相色谱—质谱联机等分析方法进行表征,并对各种光谱谱图进行详细分析。根据光谱数据分析结果确定了除草剂安全剂3-二氯乙酰基-2-甲基-2-乙基-1,3-噁唑烷的结构式。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.
