Abstract
Some p-nonylphenyl poly (oxyethylene) ether derivatives having one or two nitro groups or one or two amino groups in the aromatic nucleus were prepared. Antimicrobial activities and surface tensions of these derivatives were examined.
Surface tensions of water solutions of these derivatives were larger than that of the corresponding starting ether by 23 dyn/cm, but there was no difference in surface tension between the derivatives having one nitro or amino group and the derivatives bearing two nitro or amino groups.
Antimicrobial activity was not exhibited by the derivatives having one nitro or amino group, but that against some microorganisms was found in the derivatives bearing two nitro or amino groups. The effect of amino group on antimicrobial activity was stronger than that of nitro group.
