Zusammenfassung:	The invention relates to a system and a method for synthesizing ethyl acetate, in the system, a reduced pressure esterification tower is connected with a phase splitter through a pipeline; the bottom of the phase splitter is connected with the recovery tower through a pipeline, and the upper part is connected with the ester phase tank through a pipeline; the ester phase tank is connected with the decompression esterification tower and the dehydration tower through pipelines; the lower part of the dehydrating tower is connected with the recovery tower through a pipeline, and the upper part is connected with the refining tower through a refining feeding tank; the refining tower is connected with the product storage tank through a pipeline. The method comprises the following steps: carrying out heat exchange on excessive acetic acid and ethanol through a metering pump and a heat exchanger, feeding into a reduced-pressure esterification tower, and adding an ionic liquid catalyst; carrying out vacuumizing operatio
