The reaction mechanism and chemical reaction kinetics of N-(diethylenediamino) perfluoroheptyl acidamide is studied.by synthesized dissolvent means,N-(diethylenediamino) perfluoroheptyl acidamide was synthesized with perfluorocaprylic acid and diethylenetriamine and the high efficiency catalyst(CATP),and the reaction mechanism and chemica-l reaction kinetics are studied.The result showes that the yield could reaches to 96%,as the reaction rate k=0.7007×10-3 s-1 after 3h in 130℃.This reaction accorded with the proton condensation reaction mechanism and the first order reaction.
