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： Paired electrochemical synthesis reactions in which ethylene glycol is formed at the cathode of a membrane divided cell at high concentrations and current efficiencies, up to 99 percent. Simultaneously, a compatible process is also conducted at the anode of the same electrochemical cell by reacting indirectly generated anode products with organic substrates to form secondary products, such as polybasic acids. The process is especially advantageous in that such secondary products, where appropriate can be further reacted with the ethylene glycol prepared from the catholyte of the same cell to form useful tertiary products, especially polyesters like polyethylene terephthalate. Mole ratios of ethylene glycol and polybasic acid can be controlled through selective use of regeneratable redox reactant.
