EDA reacts with formaldehyde and sodium cyanide under the appropriate alkaline conditions to yield the tetrasodium salt of ethylenediaminetetraacetic acid (24). By-product ammonia is removed at elevated temperatures under a partial vacuum. The free acid or its mono-, di-, or trisodium salts can be produced by the appropriate neutrali2ation using a strong mineral acid. This same reaction with other amines is used to produce polyamino acetic acids and their salts. These products are used widely as chelating agents.

Many chelating agents are available commercially. The two that have come into common use for boiler deposit control are ethylenediaminetetraacetic acid (EDTA) and nitrilotriacetic acid (NTA). In practice, the tetrasodium salt of EDTA and the trisodium salt of NTA are used, rather than the acid. Both of these materials chelate bivalent and trivalent metallic ions on a mole for mole basis. The reaction rates for technical grades of EDTA and NTA are listed in Table 7.3.
