Electrosynthesis at High Surface Area Carbon and Graphite Anodes.

摘要

The number of stable, inexpensive anode materials available for the electrosynthesis of chemicals is quite limited. A series of high surface area carbons and graphites were used as anode materials for a variety of electrochemical processes. The effectiveness of the high surface area electrode vs. platinum and vitreous carbon was evaluated for four industrially important electrochemical processes. These include the synthesis of persulfate, perchlorate, dimethyl sebacate, and ozone. The results of the study demonstrated that the new inexpensive high surface area anodes were very promising candidates for the electrochemical production of dimethyl sebacate, persulfate, and perchlorate. Small scale experiments in glass cells resulted in current efficiencies of up to 70% for dimethyl sebacate, 75% for persulfate, and 86% for the synthesis of perchlorate.
