1. A catalyst for the oxidation of xylene. It is used for the production of desiccants for paints, printing and dyeing mordants, glass fiber curing accelerators, and hidden inks.
2, as a transesterification catalyst, in the production of polyester resin in an amount of about 0.01% to 0.05%, this product is mainly used for organic synthesis of oxidation catalyst (such as by the oxidation of p-xylene to obtain the basic material of polyester resin benzene Dicarboxylic acid catalyst).
3. For the dyeing and sealing treatment of oxide films, appropriate cobalt salts may also be added in the plugging solutions for anodic oxidation of aluminum and alloys to improve their sealing performance. It can also be used for adding galvanized additives and cobalt plating alloys, electroless cobalt plating, and alloy cobalt salts.
