PTA liquid catalysts include different specifications of cobalt acetate solution, manganese acetate solution, cobalt-manganese binary mixed solution and cobalt-manganese-bromine ternary liquid catalyst. Due to the improved stability of the active ingredients in the liquid catalyst, it is easier to convert into free radicals in application. It has better catalytic activity and selectivity, which is conducive to improving equipment production capacity, reducing raw material consumption, and reducing corrosion to dehydration towers; the proportion of each component of liquid catalyst can be flexibly adjusted according to needs, and can avoid the process of preparing solid catalysts Defects such as incomplete dissolution, deposition, and denaturation that are prone to occur in the system; at the same time, the liquid catalyst brings convenience to the user's batching system, saves energy and labor, and is unanimously welcomed by users. The liquid catalyst produced by our company has been widely used in domestic PTA production plants and has been well received.
