Electrochemical treatment of material produced by reaction in electrochemical cell

Abstract

Abstract A CHEMICAL REACTION IS CONDUCTED IN AN ELECTROCHEMICAL CELL TO PROVIDE A MATERIAL TO BE ACTED ON AT A CELL ELECTRODE. THUS, A SINGLE STEP OZONOLYSIS OF A CYCLIC OLEFIN WITHIN IN SITU ELECTROCHEMICAL REDUCTION TO PROVIDE A DIALDEHYDE AND/ OR A KETONE IS DISCLOSED. AN ELECTROCHEMICAL CELL, THE HYDROGEN-DEPOLARIZED ANODE OF WHICH CAN BE REPLACED BY A CONVENTIONAL PLATINUM, CARBON, NICKEL, ETC. ANODE, SUITABLY WITH A DIAPHRAGM SEPARATING IT FROM THE CATHODE IS USED, HAVING IN THE CELL AN ELECTROLYTIC SOLVENT, E.G., AN ALCOHOL SUCH AS METHANOL AND A SUPPORTING ELECTROLYTE SUCH AS AN ACID, E.G., ACETIC ACID OR A SALT THEREOF. THE OLEFIN WHICH CAN BE ONE LEADING TO THE FORMATION OF AN ALPHA, OMEGADIALDEHYDE, E.G., CYCLODODECENE, IS FED TO THE CELL TO WHICH AIR AND AZONE ARE ALSO FED INTO A LOWER PART OF THE CELL BELOW THE CATHODE, THE AIR AND OZONE BEARING SPARGED IN ONE EMBODIMENT INTO THE CELL LIQUID BELOW THE ELECTRODE CREATING A STIRRING OR MIXING ACTION AT THE CATHODE TO WHICH THE OLEFIN IS ALSO FED. COOLING IS PROVIDED TO MAINTAIN THE TEMPERATURE OF THE CELL. THE LOW CONCENTRATION OF OZONIDE IN THE OPERATION IS A FEATURE OF THE INVENTION TO PREVENT DEGRADATION AND OTHER PROBLEMS ENCOUNTERED WITH OZONIDES.
