反式2-羟基-5-仲辛基二苯甲酮肟(简称N_(510))作为铜的高效萃取剂,近年来已受到普遍重视。为满足基础研究工作的需要,制备高纯度的反式N_(510)是必要的,这方面的工作已有报导~*。本文介绍铜盐纯化法。一、试剂:除表明外,均为分析纯试剂。原料N_(510)为上海有机所的产品,经分析含量为55％。二、纯化方法:称取150克N_(510),用750ml95％。乙醇加热溶解,趁热慢慢加入800ml(CusO_4含量为40g/l)的CusO_4水溶液,然后猛烈搅拌5分钟,加200ml水,再搅拌1分钟,放置冷却至铜盐络合物与其它有机杂 Trans-2-hydroxy-5-sec-octylbenzophenone oxime (referred to as N_ (510)) as copper efficient extraction agent, in recent years has received widespread attention. In order to meet the needs of basic research work, it is necessary to prepare high-purity trans-N 510, and work in this area has been reported. This article describes the copper salt purification method. A, reagents: In addition to that, all analytical reagents. The raw material N 510 is a product of Shanghai Institute of Organic Chemistry. The content of the analysis is 55%. Second, the purification method: Weigh 150 g N_ (510), with 750ml95%. Ethanol heated to dissolve, while slowly adding 800ml (CusO_4 content of 40g / l) of CusO_4 aqueous solution, and then violently stirred for 5 minutes, add 200ml of water, and then stirred for 1 minute, allowed to cool to the copper salt complex and other organic miscellaneous
