Decyl and Nonanyl <i style="mso-bidi-font-style: normal">Bis</i>-phenols as prospective surfactant

Abstract

Four new<i style="mso-bidi-font-style:normal"> bis</i>-phenols, namely 4,4^/-decylidene <i style="mso-bidi-font-style:normal">bis</i>-(2,6-dimethylphenol) (<b style="mso-bidi-font-weight:normal">1</b>), 6,6^/-decylidenebis (2,4-dimethylphenol) (<b style="mso-bidi-font-weight:normal">2</b>): 6,6^/-decylidene <i style="mso-bidi-font-style:normal">bis</i>-(3,4-dimethylphenol) (<b style="mso-bidi-font-weight:normal">3</b>) 4, 4^/-Nonylidene <i style="mso-bidi-font-style:normal">bis</i>-(2,6-dimethylphenol) (<b style="mso-bidi-font-weight:normal">4</b>) are synthesized and characterized. The micelle formation by the compounds <b style="mso-bidi-font-weight:normal">1-4</b> in 1 : 9 water and isopropanol solvent have been determined and CMC are found to be 0.335, 0.477, 0.461 and 0.551 mM respectively at 26°C. These long chain <i style="mso-bidi-font-style:normal">bis</i>-phenols inhibit the cesium promoted alkylation of diethanolamine with <i style="mso-bidi-font-style:normal">p</i>-nitrobenzyl bromide.
