摘要: The invention relates to a preparation method of trifluoroacetic acid ethyl ester. comprises the following steps: evenly mixing an amine compound with ethanol in molar ratio (0.2-2):1, and then adding trichloroacetyl halide for reaction, wherein is (0.1-10):1, reaction temperature controlled at minus10-80 DEG C, time 0.5-10 hours; rectifying obtain In invention, used as binding agent, esterification carried out on ethanol, so that ester product directly obtained, thereby simplifying process not producing waste catalyst process, recycling byproducts solving environmental protection problem synthesis.
