Synthesis of nylon-6.6 using cetyltrimethylammonium chloride reverse micelles immobilized on silica surfaces

Adsorption Behavior of Curcumin onto Cetyltrimethylammonium Chloride Reverse Micelles Immobilized on a Glass Surface As Studied by Polarized Visible Attenuated Total Reflection Spectrometry with a Glass Slab Optical Waveguide

“…CTAC reverse micelles immobilized onto the SOWG surface were prepared based on the method of Fujiwara et al 8,10,23 A well made of a PTFE block [10 mm (w) × 10 mm (l) × 10 mm (h)] was built on the SOWG surface (the cover glass), which was treated with Piranha solution prior to the modification. One milliliter of a mixed solution of 1-hexanol and cyclohexane [the molar fraction (Xh) of 1-hexanol was 0.1] containing 44 mmol dm -3 CTAC was placed in the well, then a small amount of 1 mol dm -3 NaOH aqueous solution was added to the mixed solution in the well.…”

“…The immobilized reverse micelle onto the silica surface was successfully applied to the reaction medium for the synthesis of nylon-6,6 immobilized on the silica surface. 10 In an earlier work, it was demonstrated that the formed nylon-6,6 nanoclusters lay perpendicular to the glass surface plane, while location and orientation of reactants in the immobilized reverse micelles were unclear. In spite of the importance of the reverse micelles used as the reaction media, information on the characterization of the immobilized reverse micelles has been limited because of a lack of analytical methods applicable to them.…”
