“…14 Method of Addition -Corrosion rate/potentialtime response for stearic imidazoline constant concentration and variable concentration treatments (addition) as a function of dosage rate is shown in Figures 2 and 3, respectively. Depending upon the concentration and solubility of particular imidazolines/amides in CO 2 -containing brines, their solution properties vary from fairly soluble to highly dispersible.…”

Corrosion inhibition of mild steel by imidazolines and their precursors in a carbon dioxide (CO 2 )-containing environment was studied using rotating cylinder electrode (RCE) and linear polarization resistance (LPR) techniques. Corrosion rate-time/concentration profiles and minimum effective concentrations obtained for a series of imidazolines and amides were evaluated in terms of the respective contributions of their constituent parts (imidazoline ring, amide/amine group, and hydrocarbon chain) to overall corrosion inhibition. Formation of the inhibitor film was studied in terms of the bilayer/multilayer film model. FIGURE 9. Corrosion rate/potential-inhibitor concentration dependence for stearic amide/imidazoline constant concentration treatments.FIGURE 10. Corrosion rate/potential-time response for lauric imidazoline constant concentration treatment at 0 rpm and 6,000 rpm.

“…As the concentration increases the no of surfactant molecules in the water also increases. The water molecules have strong affinity for one another than that of the hydrocarbon chain and hence they withdraw from the surrounding water molecules and form the spherical micelles with their cationic head outside 10 .…”

The nano crystalline hydroxyapatite with highly uniform spherical morphology has successfully been prepared using the new cationic surfactant Cetrimide as template by co-precipitation method at ambient temperature. The sample was calcinated at 750 oC for 8h. The FTIR spectrum shows the chemical composition of HAP. The XRD pattern confirms the characteristic peaks and the hexagonal structure of HAP. The lattice parameters calculated from the XRD pattern are a = b ~ 0.93873 nm, c = 0.68486 nm, the axial ratio ~0.7296, the volume of the unit cell ~522.6535x10-30 m3. The size and morphology of the sample were analyzed by FESEM, which shows that the spherical HAp particles with diameter 150-200 nm have successfully been synthesized. All the inspections confirm the successful preparation of nano spherical HAP with excellent morphology control, and uniform size.

“…van Os et al have listed the physicochemical properties of selected anionic, cationic and nonionic surfactants [4]. Another useful text is the Handbook of Surfactants by Porter [5]. In addition, a fourth class of surfactants, usually referred to as polymeric surfactants, has long been used for the preparation of emulsions and suspensions and their stabilization.…”
