Disclosed herein is a novel class of multiple charged cationic or anionic compounds that are derived from an aza-Michael Addition reaction between a polyamine (Michael donor) and an activated olefin (Michael acceptor), methods of making the same, and use thereof. Also disclosed herein are the methods of using multiple charged cationic or anionic compounds disclosed herein in a reverse emulsion breaker composition to break reverse emulsion commonly found in a produced fluid in oil and gas operations. The disclosed REB methods or compositions are found to be more effective than those methods or compositions including commonly used for oil/solid and water separation.
