摘要
Aqueous corrosion inhibitor compositions, preferably storage-stable, useful in acidic cleaning solutions for cleaning the surfaces of metal, comprising reaction products of at least one rosin amine component, at least one non-flammable liquid ketone component, at least one carboxylic acid component, at least one paraformaldehyde component and water; aqueous acidic cleaners prepared therefrom; and methods of their use. The inventive corrosion inhibitor compositions are made by a simple process which reduces the presence of toxic and/or flammable raw materials, co-products, residual reactants and chloride ion while providing acid inhibition in aqueous acidic cleaners.
