Hydrophilicity and Acid Hydrolysis of Water-Soluble Antibacterial Iron(II) Schiff Base Complexes in Binary Aqueous Solvents

摘要

Kinetics of acid hydrolysis of seven antibacterial iron(II) Schiff base complexes has been studied. The Schiff base ligands were derived from sodium 2-hydroxybenzaldehyde-5-sulfonate and a series of amino acids. The hydrolysis rate is studied by spectrophotometric method and compared with complex hydrophilicity. Addition of the organic co-solvent, dimethylsulfoxide or n-propanol, significantly accelerates the hydrolysis.
