METHOD FOR TREATMENT OF FOIL TO FACILITATE ITS SUBSEQUENT REMOVAL

摘要

Method for treatment of oil on a solid or liquid surface to facilitate subsequent removal of the oil from the surface. A fat-soluble metal containing substance comprising an organic anion and a metallic cation is added to the oil. The metal containing substance may be prepared by allowing a metal salt to react with an acidic organic compound in a process in which a suitable oxidation agent ensures that all the metal in the end product is present at its highest stable oxidation state while at least one volatile compound is formed during the preparation. A polymeric material with a high specific surface area may optionally be added or a prepolymer for allowing subsequent formation of such a polymeric material.
