    • PROBLEM TO BE SOLVED: To provide a method and an apparatus for extracting an aromatic halogen compound, which can efficiently extract a lipophilic aromatic halogen compound from an aromatic halogen compound-containing oil to be treated. SOLUTION: In the method for extracting an aromatic halogen compound from an aromatic halogen compound-containing oil 11 to be treated, the pH of the oil 11 to be treated is adjusted to pH 9 or higher and then a polar extraction solvent 13 selected from among alcohol and ketone each having a boiling point of 80°C or lower is added to and mixed with the pH-adjusted oil to be treated. The mixture is subjected to gravity separation at a temperature of 15°C or lower to extract the aromatic halogen compound on the polar extraction solvent side. COPYRIGHT: (C)2011,JPO&INPIT
    • 要解决的问题:提供一种芳族卤素化合物的提取方法和装置,其可以从含芳香族卤素化合物的待处理油中有效提取亲脂性芳族卤素化合物。 解决方案:在从待处理的含芳族卤素化合物的油11中提取芳族卤素化合物的方法中,将待处理的油11的pH调节至pH9以上,然后将极性提取溶剂13 从沸点为80℃以下的醇和酮中加入并与待调节的pH调节油混合。 将混合物在15℃或更低的温度下进行重力分离,以在极性提取溶剂侧提取芳族卤素化合物。 版权所有(C)2011,JPO&INPIT
