| titleOfInvention | Method for the preparation of organic salts of the rare earths, with good solubility in water, which possess an inhibitory action on blood coagulation |
| abstract | The invention comprises rare earth metal laevulinates and the preparation thereof by reacting in solution laevulinic acid with an inorganic alkaline rare earth metal compound. The inorganic alkaline rare earth metal compound may be "didymium," neodymium, praseodymium, lanthanum or cerium carbonate or hydroxide. The process is preferably carried out by adding laevulinic acid to an aqueous solution of the inorganic alkaline rare earth metal laevulinate, e.g. in the case of adding laevulinic acid to aqueous "didymium" carbonate and then boiling for approximately 2 hours, the pH of approximately 6 may be obtained by adding carbonic acid or didymium carbonate. The rare earth metal laevulinates may be isolated from the resulting solutions by evaporation to dryness. In the examples "didymium," lanthanum and cerium laevulinares are prepared. |
