Paragraph 0012; 0021; 0023, (2017/01/31)
The invention discloses a method for preparing 3-amino-4,4,4-trifluorocrotonate with high raw material utilization rate. According to the invention, 4,4,4-trifluoroacetyl ethyl acetate and excessive ammonium acetate are subjected to an amination reaction to obtain a reaction solution, then the reaction solution is separated to an organic phase and an aqueous phase, ammoniacal liquor is added in the aqueous phase to obtain ammonium acetate, and finally ammonium acetate is cycled to continuous reaction.
