Several new substituted sulfonamide compounds were synthesized and their structures were confirmed by 1 H-NMR, 13 C-NMR, FT-IR, and mass spectroscopy. The antibacterial activities of the synthesized compounds were screened against standard strains of six Gram positive and four Gram negative bacteria using the microbroth dilution assay. Most of the compounds studied showed promising activities against both types of bacteria.

Factors that improved the biodegradation of surfactants have successfully used to prepare higher ordered biodegradable tris-imidazolium and benzimidazolium ionic liquids.

Novel tetrakis-imidazolium and benzimidazolium ILs containing tetra-ester groups with incorporated quadruple side chains were synthesized successfully as degradable surfactants of expected medical and industrial applications.
