Abstract :
A new mixed calixarate/stearate calcium carbonate overbased detergent has been prepared and characterised by 1H NMR, 13C NMR, IR, Raman and UV-Vis spectroscopic methods. In addition, Langmuir trough and dynamic light scattering experiments have been carried out. These are interpreted in terms of a calcium stearate- and calcium calixarate-stabilised CaCO3 particle of ca. 6 nm diameter; there is evidence for a reservoir of excess surfactant inverse micelles.
