摘要：
New compounds are represented by Formulas 1 and 2 where Formula 1 is:
wherein each of R 1 , R 2 , R 3 , and R 4 is independently H, hydroxyalkyl, -C(R 6 ) 2 COOH or ammonium, amine, or alkali metal salts thereof; R 5 is an alkylene group having at least one carbonyl group; and each R 6 is independently selected from H, and alkyl groups of from 1 to 4 carbon atoms, straight or branched chain, preferably H, -CH 3 , or -C 2 Hs, more preferably each R 6 is H and Formula 2 is:
wherein R 1 , R 2 , R 3 , R 4 , R 5 and R 6 are defined for Formula 1, preferably at least 3, most preferably 4 of R 1 , R 2 , R 3 , and R 4 are independently -C(R 6 ) 2 COOH or salts thereof; and each R 7 is independently R 5 or an alkylene group. The compounds are advantageously photo- and bio-degradable and are particularly useful as chelants especially in washing compositions and in gas conditioning.
