摘要： A method for heterocycle catalyzed electrochemical reduction of a carbonyl compound is disclosed. The method generally includes steps (A) to (C). Step (A) may introduce the carbonyl compound into a solution of an electrolyte and a heterocycle catalyst in a divided electrochemical cell. The divided electrochemical cell may include an anode in a first cell compartment and a cathode in a second cell compartment. The cathode generally reduces the carbonyl compound to at least one aldehyde compound. Step (B) may vary which of the aldehyde compounds is produced by adjusting one or more of (i) a cathode material, (ii) the electrolyte, (iii) the heterocycle catalyst, (iv) a pH level and (v) an electrical potential. Step (C) may separate the aldehyde compounds from the solution.

摘要： In a method for producing adiponitrile by electrolysis of an acrylonitrile composite stream passing through an undivided electrolytic cell having a cathode and an anode, flow of the acrylonitrile composite stream to the cell is periodically terminated, a wash stream is passed through the cell in contact with the cathode and anode, said wash stream being a basic aqueous solution having a concentration in the range of about 120 weight percent basic compound in the solution. The wash stream is passed through the cell in contact with the cathode and anode for a period of time in the range of about 1-60 minutes and thereafter the passage of the wash stream through the cell is terminated and the acrylonitrile composite stream is passed to the electrolytic cell for electrolysis.
