Novel ester derivatives of ether polycarboxylic acids and process for making same |
| abstract |
Novel polyfunctional compounds which may be hydrolyzed to the corresponding salts, which in turn are metal sequestering agents, are disclosed, as well as a novel method for their preparation. The compounds are the reaction product obtained from the reaction of selected salts of monoalkyl esters of maleic acid with selected active hydrogen containing compounds. These products are prepared by a reaction of the starting materials in preferably a substantially anhydrous medium at an elevated temperature. |
