Products for inhibiting corrosion and for protection against corrosion

Anti-corrosion agents are prepared by reacting an alkali metal nitrile with a natural resin containing free abietic acid, e.g. tall oil. An aqueous solution of the nitrile is preferably employed at a temperature below 60 DEG C. The abietic acid or material containing it may be an alcoholic solution to give a solution of the product in alcohol. Reaction may be performed in a composition whose anti-corrosive properties are to be inhibited or in a composition to be used for protecting against corrosion. Thus when neutralizing compositions containing abietic acid the aqueous alkali used, e.g. caustic potash may contain the alkaline nitrile in solution, to produce an agent for emulsifying mineral oil to give an emulsion which is non-corrosive or may even be used for preventing corrosion. Water-soluble products yielding anti-corrosive coatings removable with water or aqueous alkali may be obtained by mixing with soaps, aminoalcohol soaps or alkaline sulphonates. Products insoluble in water giving ...

In some embodiments, fluorosurfactants include a fluorophilic tail soluble in a fluorophilic (e.g., fluorocarbon) continuous phase, and a headgroup soluble in either an aqueous phase or a lipophilic (e.g., hydrocarbon) phase.
