What is the organic electrochemical synthesis? • The electrochemical synthesis of organic compounds is the science of synthesizing organic compounds with the help of electrochemical methods. organic electrochemical synthesis electrochemistry organic synthesis chemical engineering It’s an intersectant science

The characters oforganic electrochemical synthesis Comparing with the traditional TERRACE organic synthesis, the organic electrochemical synthesis shows obvious superiorities 1. The electrochemical reactions can be achieved e⊥ ectro through the loss and transfer acquisition of electron on the electrode with reactants. It decreases the consumption of substance and reduce the side reactions. The reaction efficiency is enhanced
