Abstract
Abstract BASIC COBALT SALTS OF NEODECANOIC ACID HAVE A STIOCHIOMETRIC EXCESS OF COBALT RELATIVE TO THAT ACID, AS COMPARED WITH NUETRAL COBALTOUS SALT OF THE ACID, AND ARE OIL-SOLUBLE. THUS THEY ARE USEFUL WITH HYDROCARBON DILUENT AS DRIER COMPOSITIONS AND IN DRYING OIL COMPOSITIONS. THE DRIER COMPOSITIONS CAN CONTAIN A HIGH COBALT CONTENT, E.G., 12% COBALT BY WEIGHT OF THE DRIER COMPOSITIONS. THESE SALTS HAVE AN AMOUNT OF METAL SUCH THAT THE SUM OF THE STIOCHIOMETRIC AMOUNT OF THE METAL AND THE EXCESS CORRESPONDS TO AT LEAST ABOUT 115% OF THE AMOUNT FOR NUETRALIZATION OF THE ACID BY COBALT METAL. THE PROCESS USED TO MAKE SUCH AS SALT REACTS AN EXCESS OF THE METAL WITH THE ACID IN THE PRESENCE OF WATER AND OXYGEN-CONTAINING GAS FOR A TIME LONGER THAN REQUIRED TO NUETRALIZE THE ACID WITH METAL. THEN WATER IS REMOVED.
