Abstract
Several recent studies have shown that many oils, such as hydrocarbons, fluorocarbons, silicone and natural oils, are more readily dispersed as fine (micron-sized) droplets in water when the mixtures are almost completely degassed. These observations have not yet been fully explained and so this paper examines the nature of hydrophobicity of a wide range of oils and considers both the cavitation process and the surface charging expected during the separation of hydrophobic materials in water. Cavitation inside porous hydrophobic solids immersed in water is also considered. We also introduce a quick, easy and alternative method to freeze–thaw degassing, by which enhanced dispersions can be formed, which gives further support to the central role of degassing.
