Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
105 words
A PROCESS FOR PREPARING A STABLE COLLOIDAL COMPLEX CONTAINING MOLYBDENUM WHICH COMPRISES EXTRACTING AN ACIDIC AQUEOUS SOLUTION OF A MOLYBDENUM COMPOUND, SELECTED FROM THE GROUP CONSISTING OF MOLYBDIC ACID, AMMONIUM SALTS OF MOLYBDIC ACID AND METAL SALTS OF MOLYBDIC ACID, WITH A KETONE HAVING IN THE RANGE OF 4 TO 10 CARBON ATOMS, SAID ACIDIC SOLUTION HAVING BEEN ACIDIFIED WITH A MINERAL ACID TO AN ACIDITY WITHIN THE RANGE OF 2 N TO 12 N, DISPERSING THE RESULTANT KETONE EXTRACT IN AN OIL-SOLUBLE BASIC METAL-CONTAINING DISPERSANT HAVING SUFFICIENT ALKALINITY TO NEUTRALIZE THE FREE ACIDITY OF SAID EXTRACT, AND THEN REMOVING THE KETONE FROM THE DISPERSION.
