Activity Description
The production activities of this product include cobalt bromide synthesis, manganese bromide synthesis, manganese acetate synthesis, cobalt manganese bromide ternary catalyst synthesis and other processes.
Process Description
The cobalt–manganese–bromide composite catalyst is a liquid-phase oxidation catalyst composed of cobalt salt, manganese salt, and bromide as core active ingredients in a specific proportion (approximately 4% w/w cobalt, 4% manganese, and 20% w/w bromine). It exhibits active chemical properties, combining the catalytic synergistic effect of cobalt and manganese ions with the co-catalytic effect of bromide. Under high temperature and pressure, it can efficiently activate oxygen, accelerate the oxidation reaction process, and offer strong catalytic selectivity with few side reactions. Industrially, it is primarily used in the petrochemical sector (catalyzing the oxidation of paraxylene to produce terephthalic acid—serving as a core catalyst in the polyester industry), carboxylic acid synthesis (catalyzing the oxidation of o-xylene to produce phthalic anhydride, or the oxidation of cyclohexane to produce adipic acid), and also in fine chemicals (catalyzing the oxidation of alkyl benzene to synthesize corresponding carboxylic acids used in the production of plasticizers and detergent raw materials), polymer monomer synthesis (assisting in the preparation of monomers for polyester, nylon, and other polymer materials), and other liquid-phase oxidation reactions of aromatic or aliphatic hydrocarbons, particularly in large-scale industrial continuous production scenarios.

Technology comment
The synthesis reaction kettle is heated by a steam jacket, and the reactor operates at atmospheric pressure. The synthesis of cobalt–manganese–bromide ternary catalyst is a atmospheric-pressure process.
1. Synthesis of cobalt bromide: First, add an excess of 5% metal cobalt flakes with a purity of 99.8% into the cobalt bromide reactor, then use a pneumatic diaphragm pump to pump 48% hydrobromic acid into the hydrobromic acid high-level tank, and then add it dropwise into the reactor. After the reaction is completed, pure water is added to obtain a high-purity cobalt bromide aqueous solution.
2. Synthesis of manganese bromide: First, add an excess of 5% manganese metal flakes with a purity of 99.8% to the manganese bromide reactor, then use a pneumatic diaphragm pump to pump 48% hydrobromic acid into the hydrobromic acid high-level tank, and then add it dropwise into the reactor.
3. Manganese acetate synthesis: First, add an excess of 5% manganese metal flakes with a purity of 99.5% and a small amount of pure water to the manganese acetate reactor, then use a plastic pump to pump 80% acetic acid into the acetic acid high tank, and then add it dropwise into the reactor.
4. Synthesis of cobalt–manganese–bromide ternary catalyst: The synthesized cobalt bromide, manganese bromide, manganese acetate solution and pure water are directly passed through the pump and measured by an online mass flow meter at normal temperature and pressure, and then sent to the ternary-catalyst finished-product tank according to the proportion. Stir evenly to obtain the finished cobalt–manganese–bromide ternary catalyst.
