Title:
電気化学セルでのオニウムヒドロキシドの調製
Document Type and Number:
Japanese Patent JP4320055
Kind Code:
B2
Abstract:
A process is described for preparing onium hydroxides from the respective onium salts and for purifying onium hydroxides in an electrochemical cell. In one example, the present invention relates to a process for preparing onium hydroxides from the corresponding onium salts which comprises the steps of: (A) providing a cell comprising an anode, a cathode and one or more unit cells assembled for operational positioning between the anode and the cathode, each unit cell comprising: (A-1) four compartments defined by, in sequence beginning at the anode, a bipolar membrane, a first divider and a second divider, said bipolar membrane having an anion selective side facing the anode and a cation selective side facing the cathode.
