马来酸酯磺酸盐的制备及性能
Structure and solution properties of maleic acid ester sulfonates
摘要
Abstract
The tetradecanol,maleic anhydride,glycol and sodium bisulfate were used to synthesize three kinds of maleic ester sulfonates. The surface properties of maleic ester sulfonates in distilled water and salt solution,interfacial tension with alkanes,and wetting ability of aqueous solutions of the maleic ester sulfonates were evaluated. The results showed that critical micelle concentration(CMC) and corresponding surface tensions(γCMC) decrease with increase of temperature,sodium sulfosuccinate(GDE14S) has minimum CMC,higher surface tension,and lowest interfacial tension with alkanes,especially,the interfacial tension with octane and decane can decrease to 0.02 mN/m. Sodium monoester sulfosuccinate(MSE14S) has the highest CMC and γCMC,and the interfacial tension with alkanes is also the largest. Sodium diester sulfosuccinate(MDE14S) with double hydrophobic and single hydrophobic head group has the highest surface activity,and the interfacial activity is between MSE14S and GDE14S. Wettability of three surfactants is directly related to surface tension. The lower the surface tension,the better the wettability. Adding inorganic salts to surfactant solution can reduce CMC. The surfactant with lower surface tension has stronger wettability.关键词
