Abstract

Abstract Organic compounds have a problem that the separation of structural isomer in the preparation process requires high energy consumption. This study proposes a new separation method of structural isomer using Magneto- Archimedes method. Firstly, the levitation height of 1, 6-DDA and 1, 10-DDA was respectively calculated by simulation of the forces acting on the particles under magnetic field, and it was indicated that they could be separated by the difference of levitation height. To confirm the phenomenon experimentally, white powders of 1, 6-DDA and 1, 10-DDA were formed into pellets, and were soaked in manganese chloride solution. Then the solution was put on the center of the cryostat of HTS bulk magnet (maximum magnetic flux density is 3T). As a result, it was confirmed that the separation of structural isomer by difference of levitation height could be possible.

磁阿基米德法分离结构异构体方法的研究

摘要有机化合物在制备过程中存在结构异构体分离能耗高的问题。本研究提出了一种新的结构异构体分离方法——磁阿基米德法。首先，通过模拟磁场作用在颗粒上的作用力，分别计算了1,6 - dda和1,10 - dda的悬浮高度，并指出悬浮高度的差异可以将其分离。为了实验证实这一现象，将1,6 - dda和1,10 - dda的白色粉末制成球团，并将其浸泡在氯化锰溶液中。然后将溶液置于高温超导体磁铁的低温恒温器中央(最大磁通密度为3T)。结果表明，利用不同的悬浮高度分离结构异构体是可行的。关键词:磁选，磁阿基米德法，回收*通讯作者:nishijima@see.eng.osaka-u.ac.jp
