Title:
MULTIPLY CHARGED IONIC COMPOUNDS DERIVED FROM POLYAMINES AND COMPOSITIONS THEREOF, AND USE THEREOF AS REVERSE EMULSION BREAKERS IN OIL AND GAS OPERATIONS
Document Type and Number:
Japanese Patent JP2023052412
Kind Code:
A
Abstract:
To provide: a novel class of multiply 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; and methods of using the compounds in a reverse emulsion breaker composition to break reverse emulsion found in a produced fluid in oil and gas operations.SOLUTION: A compound is derived from an aza-Michael addition reaction between a polyamine (Michael donor) and an activated olefin (Michael acceptor) that has an ionic group according to one of the formulas in the figure, where X is NH or O.SELECTED DRAWING: Figure 1
