This invention pertains to novel multiple quaternary ammonium salts and their derivatives represented by the formula: wherein each R, R', R, R&#x2032;, R, R&#x2032;, Ror Ris independently selected from the group consisting alkyl, aryl, aralkyl and &#x2014;CH&#x2014;CH(OR)&#x2014;CHNRRR;wherein one or more Rgroup is selected from the group consisting of: and wherein Anis an anion. This invention also pertains to novel multiple quaternary ammonium salts and their derivatives represented by the formula: wherein each R, R&#x2032;, R, R&#x2032;, Ror R&#x2032;group is independently selected from the group consisting of alkyl, aryl, aralkyl and &#x2014;CH&#x2014;CH(OR)&#x2014;CHNRRR;wherein one or more Rgroup is selected from the group consisting of: and wherein Anis an anion.

Synthetic multiple quaternary ammonium salts

In one embodiment, the present invention relates to a process for recovering an onium compound from waste solutions or synthetic solutions containing the onium compound and impurities including the steps: contacting the waste solution or synthetic solution with a metal ion scavenger to remove metal ion impurities, wherein the metal ion scavenger comprises at least one of a chelating compound, a nanoporous material, and a magnetically assisted (MACS) material; charging the waste solution or synthetic solution to an electrochemical cell containing at least two compartments, a cathode, an anode and a divider and passing a current through the cell whereby the onium compound is regenerated or produced; and recovering the onium compound from the cell.
