| titleOfInvention | Determining biodegradability of iminodiacetic acid derivatives, degradable chelants, uses and compositions thereof |
| abstract | Chelants represented by Formula (Ib) are determined to be biodegradable whennDistance A is from 3.8 x 10 -10 to 4.6 x 10 -10 m, Distance B is from 5.1 x 10 -10 nto 5.9 x 10 -10 m, and Distance C is from about 4.3 to 6.7 x 10 -10 m. Compoundsnmeeting these criteria are referred to as compounds of Formula (2). Innaddition to methods of analysis and computer systems therefor, the inventionnincludes a method of chelating a metal ion to form a chelate and biodegradingnthe chelate comprising step (a) contacting the metal ion with at least onencompound of Formula (2) to form a chelate and (b) contacting the resultantnchelate or chelant with microbes of the type specified in ASTM 2667-89, ISOn5815 or effective enzymes thereof under conditions and for a time sufficientnfor biodegradation wherein either (i) the chelate formed in step (a) is formednin a process of removing deposits, scale, or rust; cleaning or washing;ncontrolling metal initiated or catalyzed oxidation or deterioration includingnspoilage, discoloration, or rancidification; textile treatment; paper making;nstabilization of polymers or phosphates; or petroleum drilling, production ornrecovery; or (ii) the chelate formed in step (a) is before step (b) used as anredox catalyst, in a process of photographic bleaching, bleach-fixing orndeveloping; in electroless deposition or plating; in removing acid or oxidengases including H 2 S, NO x , SO x , CO and CO 2 ; or in providing agriculturalnnutrients. |
