“…This is again related to the change in hydrogen bonding between the POE chain and water as salts are added (22,(23)(24)(25) (23)(24)(25). These changes in hydrogen bonding of the PEO chain are responsible for the CP behavior of F127 solutions in the presence of these salts.…”

“…The cloud points and interfacial tension with the injection brine and the field dead oil at a water-oil-ratio of ~100 at 25 ºC are shown in Table 4-2. Addition of small amounts of anionic or cationic surfactants to an aqueous solution of non-ionic surfactants increases the cloud points of the nonionic surfactants (Schott and Royce 1984). This effect is also known as salting in of the nonionic surfactant which is opposite of the salting out effect.…”

“…The salting-out as such favoured the weakening of surfactant head-water interaction. It seems that, the sodium chloride lowers the cloud point by a continuous medium change, more than that by direct interaction with the ethoxy groups of the surfactant [23][24][25][26]. Fig.…”

Two-aqueous phase extraction of phenol and benzyl alcohol as a solute from their aqueous solutions was investigated using polyethoxylated alcohols (CiEj) as a biodegradable non-ionic surfactant. First, the phase diagrams of the binary systems, water-surfactant (Oxo-C 10 E 3 and Oxo-C 13 E 9 ), and the pseudo-binary systems, water-surfactant with a constant concentration of solute was determined. The effect of sodium chloride and sodium sulphate on water-surfactant systems were studied. According to the given surfactants concentrations and temperatures, the extraction results were expressed by the following four parameters, percentage of extracted solute, E, which reached 95 and 90% for phenol and benzyl alcohol, respectively, residual concentrations of solute, X s,w , and the surfactant, X t,w , in the dilute phase and volume fraction of the coacervate at the equilibrium condition, φ c . The values of these parameters were determined by an analyzing central composite designs. After the first extraction process, phenol and benzyl alcohol concentrations in the effluent were reduced about ten times for the first and four times for the second, correspondingly.
