\begin{abstract}
An efficient method for the Beckmann rearrangement of cyclohexanone
oxime (CHO) catalyzed by trifluoroacetic anhydride (TFAA) is proposed in
this work. The effects of experimental parameters on the reaction rate
are studied, including CHO concentration, TFAA/CHO ratio, temperature,
and CPL concentration. The reaction rate shows a linear relationship
with TFAA/CHO ratio and reduces with the increasing of CPL
concentration. Based on the experimental data and the study of in-situ
FTIR, a reaction mechanism is proposed and the equilibrium relationship
between CPL and TFAA is established. A rate constant model is developed
and is in good agreement with the experimental results. The TFAA/TFA
catalytic system allows high conversion and reaction rate compared with
other organic acids.%
