Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
104 words
A PROCESS FOR PREPARING A STABLE COLLOIDAL COMPLEX CONTAINING MOLYBDENUM WHICH COMPRISES THE STEPS OF PREPARING AN ACIDIC AQUEOUS SOLUTION OF A COMPOUND OF MOLYBDENUM SLECTED FROM THE CLASS CONSISTING OF MOLYBDIC ACID AND THE HALOGEN, AMMONIUM, AND ALKALI METAL SALTS THEREOF, SAID SOLUTION HAVING BEEN ACIDIFIED WITH A MINERAL ACID TO AN ACIDITY WITHIN THE RANGE OF FROM 4N TO 8 N, EXTRACTING SAID ACDIC SOLUTION WITH A HYDROCARBON ETHER OF FROM 3 TO 8 CARBON ATOMS, DISPERSING THE RESULTANT EXTRACT IN AN OIL-SOLUBLE DISPERSANT HAVING SUFFICIENT BASICITY TO NEUTRALIZE THE FREE ACIDITY OF SAID EXTRACT, AND THEN REMOVING ETHER FROM THE DISPERSION.
