The aminolysis of ethyl acetate was promoted significantly via continuous reaction in a tubular reactor. N-propylacetamide was thus synthesized without presence of solvent and catalyst. The optimum conditions were obtained as follows:the reaction temperature is 218 °C, the reaction pressure is 3.5 MPa, the molar ratio (ethyl ace-tate:N-propylamine) is 1:1, and the residence time is 350 min. Accordingly, the conversion of ethyl acetate is up to 94.8％. Furthermore, the kinetics of the rapid reaction stage (when the conversion of ethyl acetate is 20％–80％) can be expressed as ln k=?4629.441/T+2.1366, and the apparent activation energy is Ea=38489 J·mol?1.
