Abstract:
The production technology of ethyl acetate was introduced in this work. Extraction separation results of ethyl acetate- ethano-l water were simulated with wilson equation By tr iangle-matrix method. Reflux ratio et al. effected on separation efficiency were discussed. Extraction separation apparatus was established. Separation experiment of ethyl acetate- ethano-l water was studied by two extraction solvents, composite extraction method is used for separation of ethyl acetate- ethano-l water, above 99% ethyl acetate can be obtained one time by composite extraction, ethyl acetate recovery rate reached to above 97%, also above 95% ethanol can be obtained, water quantity used is only twice times raw material, this technology is simple and energy consumption is low. Research results were provided a base for farther industry test.
