【摘要】 以马来酸酐（MA）、七甲基三硅氧烷（HTLX）、烯丙基缩水甘油醚（AGE）、水、NaHSO₃为原料经硅氢加成、环氧开环酯化、磺化反应，制备了一种阴离子表面活性剂磺基琥珀酸双酯钠盐。通过傅里叶变换红外光谱仪（FT-IR）对产物结构进行表征，并测定产物水溶液的表面张力、接触角，考察产物渗透性能、泡沫性能、乳化性能。结果表明：临界胶束浓度（CMC）为1.37 g/L，最低表面张力(γ_CMC)为20.55 mN/m，接触角在石蜡表面由61.58°降至30.37°；与磺基丁二酸-1,4-二辛酯（AOT）和十二烷基苯磺酸钠（SDBS）相比，制备的有机硅磺基琥珀酸双酯钠盐具有一般渗透性、较低起泡性和较好稳泡性，对玉米油的乳化性能优于液体石蜡。更多还原

【Abstract】 An anionic surfactant sodium salt of sulfosuccinate was prepared from maleic anhydride（MA）, heptamethyl trisiloxane（HTLX）, allyl glycidyl ether（AGE）, water and sodium bisulfite by silica-hydrogen addition reaction, epoxy ring-opening esterification reaction and sulfonation reaction. The structures of the products were characterized by Fourier Transform Infrared Spectroscopy（FT-IR）. The surface tension and contact angle of the water solution of the product were measured. The properties of the product such as permeability, foam performance and emulsion ability were investigated. The results showed that the critical micelle concentration（CMC） was 1.37 g/L, the lowest surface tension γ_CMC was 20.55 mN/m, and the contact angle decreased from 61.58° to 30.37° on the surface of paraffin wax. Compared with sulfosuccinic acid-1,4-dioctyl ester（AOT） and sodium dodecylbenzene sulfonate（SDBS）, the product has general permeability, lower foaminess and better foam stabilization, and better emulsification performance for corn oil than liquid paraffin.更多还原
