    • A process for the production of high purity ethyl acetate from ethanol is described. The process involves reacting ethanol over a suitable catalyst in a reactive distillation column. The reactive distillation setup allows overcoming the reaction equilibrium for increased conversion of ethanol. Hydrogen is removed as the distillate and ethyl acetate is obtained as a bottoms product from the reactive distillation column. A feed of hydrogen at the bottom of the column and a suitable hydrogenation catalyst placed at the bottom of the column allows for a significant reduction of impurities such as butan-2-one, butyraldehyde in the ethyl acetate product. Adding side reactors to the reactive distillation column allows additional catalyst holdup for improved reactant conversion.
    • 描述了从乙醇生产高纯度乙酸乙酯的方法。 该方法包括在反应性蒸馏塔中使合适的催化剂上的乙醇反应。 反应蒸馏装置允许克服用于提高乙醇转化率的反应平衡。 作为馏出物除去氢气,并从反应蒸馏塔作为塔底产物获得乙酸乙酯。 在塔底部的氢气进料和位于塔底部的合适的氢化催化剂允许在乙酸乙酯产物中显着降低诸如丁-2-酮丁醛的杂质。 将反应器加入反应蒸馏塔允许额外的催化剂保留以改善反应物转化率。
