ABSTRACT:
Thiacrown ether and polymeric thiacrown ether compounds are disclosed. The thiacrown ether ring structures are substituted and have from 4 to about 10 sulfur atoms on each of the crown rings. The polymeric thiacrown ether ring structures are substituted with polymers and have from 4 to about 10 sulfur atoms on each of the crown rings. The thiacrown compounds of the present invention are expected to have utility in a wide range of applications including but not limited to utility as metal ion chelating, sequestering, and complexing agents. The thiacrown compounds are also expected to have utility as corrosion inhibitors for cooling tower, boiler, and waste water systems, hydrocarbon process systems and metal surface treatments systems.
