Abstract: A COPPER-IRON GROUP METAL CATALYST USEFUL FOR THE CONVERSION OF THIOLS TO DISULFIDES IS PREPARED BY FORMING A SOLUTION OF A SUBSTANTIALLY ALKALI METAL-FREE SILICA SOL AND AN IRON GROUP METAL SALT, SUCH AS FERRIC CHLORIDE, FORMING A GELTIONOUS PRECIPITATE WHEREIN THE ATOMIC RATIO OF THE IRON GROUP METAL TO SILICON TO OXYGEN IS FROM 1:2:5.5 TO 1:12:25.5 AND DISPERSING IN SAID GELATIONOUS PRECIPITATE AN AQUEOUS SOLUTION OF A COPPER SALT, SUCH AS CUCL2, AND THEREAFTER DRYING AND CALCINING SAID COMPOSITE.
