| titleOfInvention | Separation and purification of chelating agents |
| abstract | MONOMERIC OR POLYMERIC ORGANIC CHELATING AGENTS ARE SEPARATED AND OR PURIFIED FROM NONCHELATING AGENTS, OTHER CHELATING AGENTS, AND OR ISOMERIC MATERIAL (I.E., STRUCTURAL ISOMERS, GEOMETRIC ISOMERS, AND OPTICAL ISOMERS OF THE SAME MATERIAL) BY COMPLEXATION WITH AN INORGANIC LITHIUM SALT. THE CHELATING AGENT MAY BE RECOVERED THEREAFTER BY DESTABILIZATION OF THE COMPLEX. THE CHELATING AGENT CONTAINS AT LEAST TWO TERTIARY NITROGEN FUNCTIONALITIES. |
