Abstract
Abstract Reaction mixtures comprising components (A) Group II metal salts of phosphorus-containing acids, (B) basically reacting alkali metal compounds, and (C) optionally, di- or trivalent metal-containing salts are suitable for the preparation of basic metal salt compositions of phosphorus-containing acids, with the proviso that components (A), (B), and (C) are not the same. The basic metal salt compositions are useful in the preparation of lubricants.
