Kinetics in microemulsion V. Glucose oxidase catalyzed oxidation of beta-D-glucose in aqueous, micellar and water-in-oil microemulsion media.
The oxidation of beta-D-glucose by the enzyme glucose oxidase was studied in aqueous medium, in solutions of surfactants AOT (2-ethylhexylsulfosuccinate, sodium salt) TX-100 (polyethylene glycol p-tert octyl phenyl ether) and in w/o microemulsion medium (water/AOT/decane) at different water/AOT mole ratio (omega), pH, temperature and in presence of additives. The time-dependent activities of th...
متن کاملSolubilization of water by dialkyl sodium sulfosuccinates in hydrocarbon solutions.
The apparent solubilization of water in hydrocarbon solvents by the addition of 0.1% to 2.0% w/w di-(2-ethylhexyl) sodium sulfosuccinate (AOT) has been studied. In n-octane and n-decane, transitions of clear-turbid-clear-turbid were observed with increasing water content, whereas in dodecane, tetradecane, hexadecane, cyclohexane, and toluene only one clear-turbid transition was seen. Separation...
متن کاملNanostructured Microemulsion Phase Behavior Using AOT or Extended Surfactant Combined with a Cationic Hydrotrope
The phase behavior for systems containing sodium bis(2-ethylhexyl sulfosuccinate) (AOT), with the cationic hydrotrope tetraethyl ammonium chloride (TEAC), in the presence of water and heptane were studied. Formulations of microemulsion for such systems and for systems containing the so called “extended surfactant” were carried out at different salt concentrations. Anisotropy was detected using ...
متن کاملEffects of temperature and pressure on phase transitions in a ternary microemulsion system
Temperature variation experiments of small angle neutron scattering ~SANS! and neutron spin echo ~NSE! were carried out in order to compare effects of temperature and pressure on a structural formation in a ternary microemulsion system composed of AOT ~Aerosol-OT; dioctyl sulfosuccinate sodium salt!, D2O, and n-decane. From SANS measurements, a phase transition from one-phase dense water-in-oil...
