| titleOfInvention | Chelating agents and their manganic chelates |
| abstract | Chelating agents (chelants) of the general structure:wherein: n=2-4wherebyat least two of X are of formula IIIY=COOH, -PO3H2 or o-hydroxyphenylR1, R2 and R3 are independently H or C1-C8 alkylsm=1, 2 or 3 and most preferably m=1Z and Z<1 >are unsubstituted or substituted CC<+>=C or CH or NZ1, Z2, Z'1, and Z'2 are independently selected from H (or nothing for Z2 and Z'2 if C* is N) and C1-C10 groups that optionally contain one or more N atoms (optionally attached directly to C*), whereby one of the pairs Z/Z1, Z/Z2 and Z1/Z2 and one of the pairs Z'/Z'1, Z'1/Z'2 and Z'1/Z'2 may be connected to form substituted or unsubstituted (hetero)(poly)cyclic structures of less than 20 atomsC* is either part of an aromatic (hetero)(poly)cyclic structure or linked by a double bond to Z or Z2 and/or Z' or Z'2. |
