Abstract

The properties of hydroxide surfactants are critically reviewed. The general behaviours of single tailed surfactants, viz., aggregation, CMC, thermodynamics of micellization, micellar size, composition, microviscosity, hydration, degree of ionization and electrophoretic mobility along with solution behaviours of double tailed hydroxide surfactants are highlighted.

Keywords

Abstract

A polymeric amphiphile was synthesised by addition of phosphonate groups to asymmetric terminal double bonds of polybutadiene giving α, β-unsaturated phosphonic acids. The polymer was characterized by NMR and FT-IR. The synthesis produces a complex cream-like O/W emulsion containing simultaneously water and toluene. The oil droplets are interconnected by polymer chains avoiding the dispersion of the emulsion in water. When this emulsion is spread on a crude petroleum overflow on water, the oil stain shrink and is absorbed by the cream-like emulsion. The resulting product can be manipulated more easily than the original oil to extract it from the water surface.
