- Abstract
Dicationic imidazolium surfactants of the 1,1′-(2-hydroxypropan-1,3-diyl)bis(3-alkyl-1H-imidazol-3-ylium)chloride series with a variable hydrophobic chain length have been synthesized and characterized. The values of their critical micelle concentration have been determined by tensiometry, conductometry and spectrophotometry. Significant antimicrobial activity of these surfactants against a number of pathogenic bacteria and fungi was revealed. It was found that decyl and dodecyl derivatives turned out to be leader compounds, which surpassed reference antibiotics in their action and showed activity against resistant strains. The kinetic parameters reflecting the high catalytic effect of the tested dicationic imidazolium surfactants in the alkaline hydrolysis of 4-nitrophenyl esters of phosphonic, phosphoric, and toluenesulfonic acids have been obtained.
