Relationship between foaming properties and solution properties of protein/nonionic surfactant mixtures

The foaming properties of bovine serum albumin (BSA), in the absence and presence of Triton X-100 (TX-100), have been investigated using shaking tests. The results showed that increases in the TX-100 bulk concentration rapidly reduced both foam height and foam stability at TX-100 concentrations below about 0.25 mM, but increased foam height and foam stability at TX-100 concentration above 0.3 mM. The interaction between BSA and TX-100 has been studied using fluorescence spectroscopy. The surfactant appeared to bind to BSA with a low molar ratio (about one surfactant molecule per protein molecule) at concentrations below the critical micelle concentration (CMC); the binding became weaker at concentrations above the CMC. It was confirmed that protein-protein or protein-surfactant interactions had significant influence upon foaming properties of mixed protein/surfactant system.     

Solvent free telomerization of butadiene with water into octadienols in the presence of nonionic surfactant: efficient micellar catalysis

Telomerization of butadiene with water into 2,7-octadien-1-ol using a palladiumhydrosoluble phosphine system was investigated. The reaction was carried out without solvent in the presence of carbon dioxide and a nonionic surfactant. Promoted effect of neutral surfactant appeared above the critical micelle concentration and the conversion and the selectivity depended on the structure of nonionic surfactant hydrophilic part. The role of the nonionic surfactant is discussed.

The effect of nonionic surfactant structure on hemolysis

The hemolytic properties of polyoxyethylene-type nonionic surfactants were investigated in the concentration range of 0.1–5.0 wt/vol%. The effects of hydrophiliclipophilic balance, molecular weight, chemical structure and solubilizing ability of the nonionic surfactants in hemolysis are discussed. Bulky surfactants with three or four alkyl chains in their molecules, which show low solubilizing ability of lipids, were the least likely to induce hemolysis. Morphological observations of erythrocytes by video-enhanced microscopy showed that linear surfactants induce the formation of spherocytes and cause hemolysis, whereas bulky surfactants induce only morphological changes from discocytes to spheroechinocytes.     

非离子表面活性剂为溶媒的浊点萃取技术

添加剂对非离子表面活性剂浊点的影响

研究了十二烷苯磺酸钠（LAS）、正丁醇、仲丁威对非离子表面活性剂TX－10浊点的影响。LAS与TX－10形成混合胶束，使TX－10增溶能力提高，浊点也提高；正丁醇对其影响比较复杂，少量正丁醇对浊点没有影响，当正丁醇量较大时，使单独TX－10体系浊点降低，使混合体系浊点略有升高；仲丁威使其浊点下降。正丁醇、仲丁威对TX－10浊点的影响与它们在胶束中的增溶位置有关。     

Solubilization behavior ofn-octane andn-octanol in polyoxyethylated nonionic micelles

The solubilization ofn-octane andn-octanol in nonionic micelles was investigated by means of various techniques including solubilization, fluorescence and dynamic light-scattering measurements. With respect to the effect of oxyethylene chainlength of the surfactants, different solubilization behavior was observed betweenn-octane andn-octanoli.e., the solubilization ofn-octane decreases with an increase in oxyethylene chainlength, while that ofn-octanol increases. This solubilization behavior is explained from the standpoint of the volume of hydrophobic and hydrophilic regions in a micelle.
