    • A high purity refining method of acetone is provided to refine acetone containing organic impurity and inorganic metallic impurity through an ion exchange resin tower and a batch type distillation tower containing zeolite 4A. A high purity refining method of acetone comprises (1) a step for obtaining refined acetone by injecting the collected acetone containing organic impurity, inorganic metallic impurity and moisture to the top of a tower having ion-exchange resin at a flow rate of 10~100 cc /minute . g (the flow rate of the collected acetone per the ion-exchange resin gram); and (2) a step for obtaining acetone by injecting the first refined acetone in a batch type distillation tower continuously and distilling it at a distillation temperature of 60~80 °C with the reflux ratio of 2~6. The batch type distillation tower contains 1~5 % of zeolite 4A based on the weight of the collected acetone.
    • 提供丙酮的高纯度精制方法,通过离子交换树脂塔和含沸石4A的间歇式蒸馏塔来提炼含丙酮的有机杂质和无机金属杂质。 丙酮的高纯度精炼方法包括:(1)通过将收集到的含丙酮的有机杂质,无机金属杂质和水分注入到具有离子交换树脂的塔顶部以10〜100的流速获得精制丙酮的步骤 cc /分钟。 g(离子交换树脂克收集的丙酮的流量); 和(2)通过在间歇式蒸馏塔中连续注入第一精制丙酮并在60〜80℃的蒸馏温度下以2〜6的回流比蒸馏得到丙酮的步骤。 基于收集的丙酮的重量,间歇式蒸馏塔含有1〜5%的沸石4A。
