EFFECT OF ALCOHOL AND SALT ON SOLUBILIZAT ION OF WATER IN REVERSE MICELLES FORMED BY DODECYLAMMONIUM PROPIONATE IN CARBON-TETRACHLORIDE

The effect of alcohols with different chain lengths and sodium chlorid e on the solubilization of water of the dodecylammonium propionate (DA P) reverse micelles in carbon tetrachloride has been investigated. At fixed DAP concentration, the water solubilization vs, ROH concentratio n curves pass through a maximum value. For the alcohols studied in thi s work, the longer the hydrocarbon chain of an alcohol, the larger the water solubilisation. Moreover, at fixed DAP concentration and ROH co ncentration(at which the water solubilization curve shows maximum) the addition of sodium chloride will decrease the solubilization of aqueo us solution, According to the consideration of the polarity of the org anic phases, the distribution of the surfactant between the organic ph ase and interfacial region and the salting effect, the results have be en explained reasonably.
