ABSTRACT:
Thixotropic magnesium-containing complexes are prepared by heating a mixture of magnesium hydroxide, magnesium oxide, hydrated magnesium oxide or a magnesium alkoxide; a carboxylic acid, a mixture thereof with a sulfonic or pentavalent phosphorus acid, or an ester or salt of either of these; water (optional under certain conditions); and an organic solubilizing agent (which may be liquid or solid at ambient temperature) for the acid or ester. The amount of magnesium is such as to provide a basic composition. The resulting complexes may be obtained in liquid or solid form, and are useful as additives for lubricants and fuels and as protective coating compositions for metal surfaces (such as automotive undercoats and frame coatings).
