Influence of pH on Stability and Dynamic Properties of Asphaltenes and Other Amphiphilic Molecules at the Oil−Water Interface
Abstract
Oil-in-water emulsions are currently being investigated to facilitate the transport of viscous heavy oils. The behavior of these emulsions is largely controlled by the interfaces between oil drops and water. The surface-active components of crude oil, such as asphaltenes and naphthenic acids, compete among themselves at these interfaces and also with possibly added synthetic surfactant emulsifier. Here, we present a study of dynamic interfacial tension of interfaces between water and a model oil (toluene) in which variable amounts of asphaltenes are solubilized. We show that pH has a strong influence on interfacial properties of asphaltenes at the oil/water interface. At high or low pH, asphaltenes functional groups become charged, enhancing its surface activity. The influence of lower-molecular-weight surface-active species, such as the natural naphthenic acids contained in maltenes (crude oil without asphaltenes), has been investigated, and an interaction between asphaltenes and maltenes that facilitates molecular arrangement at the interface was detected. Several micropipette experiments, in which micrometric drops have been manipulated, are also described and indicate that very little coalescence of water droplets is observed at high or low pH. The microscopic properties of the interface and the macroscopic behavior of the emulsion are determined to be correlated.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
