摘要

Abstract

The aminolysis of ethyl acetate was promoted significantly

via

continuous reaction in a tubular reactor.

-propylacetamide was thus synthesized without presence of solvent and catalyst. The optimum conditions were obtained as follows:the reaction temperature is 218℃

the reaction pressure is 3.5 MPa

the molar ratio (ethyl acetate:

-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

--4629:44 1/

+ 2:1366

and the apparent activation energy is

=38489 J·mol
