Polyoxyethylene octylphenyl ether

Guizard et al. [84,85] studied the acid-catalyzed hydrolysis and condensation of titanium alkoxides [i.e., titanium isopropoxide (TIPO) and titanium tetrabutoxide (TTBO)] in polyoxyethylene- )-octylphenyl ether/decane/water microemulsions. The nonionic surfactants used were Triton X-15 (TX-15), TX-35, and TX-45. Dynamic light scattering [85] showed that the hydrodynamic radii of droplets in the TX-35/decane/water system increased from about 2,2 nm in the absence of water to about 4 nm at water/surfactant molar ratio R = 2. The radius remained approximately constant up to about R = 4, above which phase separation occurred. The constant droplet size observed above R = 2 suggests that 2 mol HiO per mole of surfactant is needed for the hydration of the polar groups.

Unlike TEOS hydrolysis, Si02 particles have been also prepared by hydrolysis of Na2Si02 and Na4Si02 in nonionic reversed micelle systems. Spherical and poly-disperse particles of 31.8 nm mean diameter were produced in polyoxyethylene(9.5) octylphenyl ether-hexanol-cyclohexane systems (25), but more uniform and dense particles were precipitated by hydrochloric acid-catalyzed hydrolysis in a mixture of polyoxyethylene(5) nonylphenyl ether and polyoxyethylene(9) nonylphenyl ether in cyclohexane systems at pH 11 (26). The uniform particle formation at higher pH is attributed to the charge repulsion by OH- adsorbed on particle surface. The particles of specific surface area of 347 m2 g-1 can be obtained by calcination of particles produced at pH 2. 

Otsuki and Shiraishi [3] used reversed phase absorption liquid chromatography and field desorption mass spectrometry to determine polyoxyethylene alkylphenyl ether non ionic surfactants in water. In the separation of polyoxyethylene octylphenyl, nonylphenyl and dodecylphenyl ethers by gradient elution with a holding process by holding the...

Cerium (IV) oxide nanoparticles were synthesized by Masui et al [236] by use of a two-microemulsion technique. One of the microemulsions contained polyoxyethylene(lO) octylphenyl ether (OP-10) as the surfactant, n-hexyl alcohol as the co-surfactant, cyclohexane as the continuous phase, and an aqueous solution of cerium nitrate as the droplet phase. The second microemulsion was the same except that the droplet phase was an aqueous ammonia solution. The two were mixed to cause precipitation the particles thus obtained were gathered by centrifugation and washing under sonication with methanol, deionized water and acetone. The final treatment involved freeze-drying and vacuum drying. The mean particle size varied with experimental conditions in the range 2.5-4.0 nm.
