A new synthetic route to a mild surfactant disodium lauryl glucoside sulfosuccinate (AG‐SS) containing two hydrophilic groups is described and its measured physicochemical properties reported. AG‐SS was synthesized from lauryl glucoside reacted with maleic acid anhydride, and then sulfonated with sodium sulfite. The structure and composition of the product were defined by Fourier transform infrared spectroscopy and liquid chromatography–mass spectrometry. The surface activity measurement showed that the critical micelle concentration (CMC) and that the surface tension at CMC (γCMC) of AG‐SS were 2.59 × 10?4 mol/L and 35.21 mN/m at 25 °C, respectively. AG‐SS exhibited excellent water solubility eliminating the disadvantage of lauryl glucoside; its foaming ability was also remarkable.  相似文献

A series of disodium alkyl monoglucoside citric monoesters (AG‐EC) were synthesized with an indirect method using glucosides, lauryl/decyl/octyl alcohol and citric acid. The structure and composition of the synthesized surfactants were defined by Fourier transform infrared spectroscopy (FTIR) and liquid chromatography–mass spectrometry (LC/MS). The surface properties, foaming ability and wetting ability were investigated. AG‐EC surfactants exhibited excellent water solubility which eliminated the defect of long‐chain alkyl glucoside. All three surfactants showed high surface activities. AG12‐EC and AG10‐EC showed remarkable foaming abilities in distilled water and hard water. Aqueous solutions of AG‐EC surfactants spread slowly on a parafilm surface.  相似文献

新型混合反胶团萃取溶菌酶的平衡行为   总被引:3,自引:0,他引:3  
研究了由阴离子表面活性剂二-(2-乙基己基)琥珀酸酯磺酸钠(AOT)和非离子表面活性剂聚氧乙烯基(聚合度为4)壬基酚醚(OPE4)组成的一种新型混合反胶团体系及其萃取溶菌酶的平衡行为. 结果表明,该反胶团体系具有较大的含水量,且其含水量在较大的表面活性剂配比(0~0.8)范围内维持恒定,是由静电作用和胶束形态改变共同作用的结果. 无机盐种类和离子强度对上述混合反胶团的含水量有着显著的影响,继而影响到溶菌酶的萃取率. 它可归结为盐离子对扩散双电层和水化膜斥力的因素所致. 降低pH和提高总表面活性剂浓度均有利于溶菌酶的萃取.  相似文献

This paper reports on experimental results of aqueous heterophase polymerizations with monomers of quite different solubility in water ranging from the water-soluble 2-hydroxyethyl methacrylate to lauryl methacrylate with solubility in water of only about 10−4 mM. A calorimetric study revealed the strong influence of both the hydrophilicity of the monomer and the stirrer speed on the rate of polymerization in the absence of surfactants. In order to obtain maximum latex yield and high efficiency (which is a measure considering colloidal properties, polymerization recipe, and polymerization parameters) the initiator-surfactant combination must be properly chosen in dependence on the hydrophilicity of the monomer. Results are presented for sodium alkyl sulfates or disodium-N-stearoyl-l-glutamate as surfactant and potassium peroxodisulfate, or poly(ethylene glycol)-azo- compounds, or 2,2′-azobis(N-2′-methylpropanoyl-2-amino-alkyl-1)-sulfonates as initiators.  相似文献

A series of ethoxylated sodium monoalkyl sulfosuccinate (ESMASS) ester surfactants were prepared by reacting polyethylene glycol (molecular weight 600) with sodium monoalkyl sulfosuccinate (SMASS). The esters were prepared by reacting octyl, lauryl, or cetyl alcohol with sodium sulfosuccinate (SSS) to prepare E(14)SMOSS, E(14)SMLSS, and E(14)SMCSS. The chemical structures of the prepared surfactants were confirmed by Fourier transform infrared (FTIR) and 1H-NMR spectroscopy. The surface tension of the synthesized surfactants was measured at 25 °C individually or mixing at different molar fractions with sodium dioctyl sulfosuccinate. The surface active properties were calculated and the micellization process of the mixture was investigated. The molar ratio of anionic (SDOSS) and anionic–nonionic surfactant moieties [E(14)SMOSS, E(14)SMLSS, and E(14)SMCSS] in the mixed aggregates were deduced using the regular solution approximation equations. Depending on the critical micelle concentration values measured for each surfactant individually, and as well as the mixed systems, the minimum surface tension was exhibited at a ratio of 0.6 SDOSS:0.4 E(14)SMCSS. The micellar composition of the mixed aggregates were explained and discussed based on the effect of their chemical structures. The activity coefficient (f 1, f 2), interaction parameter (β), and ideality of anionic–nonionic mixed aggregates were evaluated.

Solubilizing alterations caused by a series of alkyl glucosides (alkyl chain lengths ranging from C8 to C12) in phosphatidylcholine (PC) unilamellar liposomes were investigated. Surfactant-to-phospholipid molar ratios (Re) and bilayer/aqueous phase partition coefficients (K) were determined by monitoring changes in static light scattering (SLS) of the system during solubilization. At the two interaction levels investigated (surfactant concentrations producing SLS values of 100 and 0% for each surfactant/PC system studied) the free surfactant concentration for each surfactant was always comparable to its critical micelle concentration (CMC). This indicates that liposome solubilization was mainly ruled by mixed micelle formation. A rise in CMC (or decrease in the surfactant alkyl chain length) resulted in an increase in the ability of these surfactants to saturate or solubilize PC liposomes and, inversely, in an abrupt decrease in their affinity with these bilayer structures. The overall balance of these opposite tendencies shows that the octyl glucoside had the highest ability to saturate and solubilize liposomes (lowest Re values), whereas the dodecyl glucoside exhibited the highest degree of partitioning into liposomes or affinity with bilayer structures (highest K values). From a practical viewpoint, the use of nonyl glucoside reduced approximately 2.5 times the concentration needed to saturate and solubilize 1.0 mM PC liposomes with respect to that needed using the conventional octyl glucoside.  相似文献
