1-Hexene, 1-dodecene, and 1-tetradecene were solubilized in aq. 25, 45, and 50% BuOH-Na dodecyl sulfate (SDS) systems at 20 degrees C and 250 rpm. To solubilize an olefin, BuOH and SIDS must be within 25-50% and min. 5 g/100g, resp. With 37.5 g SDS/100 g and 25% BuOH, 100 g of the aq. phase solubilized 145 g 1-hexene, and with 40 g SIDS, 35 g 1-dodecene or 24 g 1-tetradecene. Up to 40% BuOH, solubilization remained unaffected. With 30 g SDS and 45 (50%) BuOH, 94 (100) 1-dodecene or 55 g (73 g) 1-tetradecene was solubilized. With 3% of tri-Na salt of tri(m-sulfophenyi)phosphine added to aq. 45% BuOH, solubilization of 1-dodecene started only at 22.5 g SDS, but then rose abruptly and, at 30 g SIDS, was higher by 60% than that with no electrolyte added, and continued to rise as SDS was increased.
