摘要: 研究了己醇、辛醇、癸醇和月桂醇对丙酸十二铵(DAP)-四氯化碳反胶束溶液增溶水和氯化钠水溶液的影响。在DAP浓度固定时,水增溶量对醇浓度的关系出现极大值,在醇浓度相同时,长碳链醇较短碳链醇有更大的增溶水能力。在固定DAP浓度和增溶水量最大时,氯化钠的存在将导致水溶液增溶量的显着下降。乙酸十二铵(DAA)、DAP和丁酸十二铵(DAB)的四氯化碳溶液对氯化钠水溶液的增溶量随氯化钠浓度的升高而有不同的走向,DAA增溶量逐渐升高,DAP先升高后下降,并出现最大值,而DAB则单调下降。

Abstract: The effect of alcohols with different chain lengths and sodium chloride on the solubilization of water of the dodecylammonium propionate(DAP) reverse micelles in carbon tetrachloride has been investigated.At fixed DAPconcentration,the water solubilization vs.ROHconcentration curves pass through a maximum value,For the alcohols studied in this work,the longer the hydrocarbon chain of an alcohol,the larger the water solubilization.Moreover,at fixed DAPconcentration and ROHconcentration (at which the water solubilization curve shows maximum) the addition of sodium chloride will decrease the solubilization of aqueous solution.According to the consideration of the polarity of the organic phases,the distribution of the surfactant between the organic phase and interfacial region and the salting effect,the results have been explained reasonably.
