摘要：

Oleic acid, chemically adsorbed on surfaces of certain minerals, undergoes oxidation of the double bonds in aqueous media at elevated temperatures. The oxidatively cross-linked molecules increase the hydrophobicity of the mineral surface dramatically. The reaction has been shown to take place on the surfaces Of CaF2 and MgCO3 but not on CaCO3. Molecular modeling of the resultant product (rather than the prereaction molecular organization) on the surfaces of CaF2 and CaCO3 provides a rational explanation for the difference in behavior.
