Rheological Properties of Interfacial Layers Formed by Iron and Aluminum Soaps, Used in Reversible Emulsions in Petroleum Industry
In connection with the application of water-in-oil concentrated emulsions in the petroleum industry, emulsified hydrocarbon films, rheological properties of interfacial layers formed by aluminum and iron soaps of synthetic fatty acids (SFA), C17-C20, and stabilities of model systems were studied. It was found that sufficiently thick (700Å) structured interfacial layers having mechanical properties similar to those of solid-like bodies were the basic stabilizing factors for water-in-oil concentrated emulsions.
