Electrohydrodimerization of aliphatic olefins with electrochemical potential pulses
Methods of making aliphatic compounds having two or more electron withdrawing groups and compositions comprising aliphatic organic compounds having one or more electron withdrawing groups. The methods are based on electrohydrodimerization of aliphatic olefinic compounds having one or more electron withdrawing groups using pulsed potential waveforms. A method may produce adiponitrile by electrolysis of acrylonitrile using pulsed waveforms. A composition may be an electrochemically produced organic phase composition. A composition may comprise one or more undesirable products, such as, for example, propionitrile, AN-derived oligomers, and the like. A composition may not have been subjected to any purification and/or separation after electrochemical production of one or more aliphatic compounds comprising two or more electron withdrawing groups.
Molten carboxylate electrolytes for electrochemical decarboxylation processes
Molten salt electrolytes are described for use in electrochemical synthesis of hydrocarbons from carboxylic acids. The molten salt electrolyte can be used to synthesize a wide variety of hydrocarbons with and without functional groups that have a broad range of applications. The molten salt can be used to synthesize saturated hydrocarbons, diols, alkylated aromatic compounds, as well as other types of hydrocarbons. The molten salt electrolyte increases the selectivity, yield, the energy efficiency and Coulombic efficiency of the electrochemical conversion of carboxylic acids to hydrocarbons while reducing the cell potential required to perform the oxidation.

Neutralization and containment of redox species produced by circumferential electrodes
There is disclosed an electrode array architecture employing continuous and discontinuous circumferential electrodes. There is further disclosed a process for the neutralization of acid generated at anode(s) by base generated at cathode(s) circumferentially located to each other so as to confine a region of pH change. The cathodes can be displayed as concentric rings (continuous) or as counter electrodes in a cross pattern (discontinuous). In this way reagents, such as acid, generated in a center electrode are countered (neutralized) by reagents, such as base, generated at the corners or at the outer ring.
