Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of metal acetate synthesis, in particular to a high-efficiency synthesis method of metal acetate. BACKGROUND
[0002] Cobalt acetate and manganese acetate are key catalysts in the synthesis of purified terephthalic acid and have important applications in chemical production. In the prior art, cobalt acetate or manganese acetate is synthesized mainly by nitric acid method and acetic acid hydrogen peroxide method. Among them, the nitric acid method has high risk of raw materials and is prone to safety accidents in the production process, so its application is limited in industrial production. The acetic acid hydrogen peroxide method is more commonly used in industry, and its reaction principle is as follows:
[0003] Co+2CH3COOH+H2O2→Co(CH3COO)2+2H2O;
[0004] Mn+2CH3COOH+H2O→Mn(CH3COO)2+2H2O.
[0005] Currently, the acetic acid hydrogen peroxide method uses a packed tower as a reactor in industrial production. The operation mode is as follows: metal cobalt or manganese is stacked in the reactor, then the mixed solution of acetic acid and hydrogen peroxide is heated to 95-110℃, and is continuously sprayed from top to bottom into the packed tower, and finally the outlet liquid is collected to obtain cobalt acetate or manganese acetate solution. However, due to the limitation of solid-liquid phase mass transfer efficiency, the mass fraction of cobalt ions and manganese ions in the final outlet liquid is generally lower than 5%, which cannot directly reach the concentration index of finished product sales, and additional subsequent concentration treatment is required, increasing the complexity and cost of the production process. Therefore, it is of great practical significance to develop a synthesis method of cobalt acetate and manganese acetate that can improve reaction efficiency and increase product concentration. SUMMARY
[0006] The purpose of the present application is to provide a high-efficiency synthesis method of metal acetate to solve the problem of low reaction mass transfer efficiency in the production process of manganese acetate or cobalt acetate, resulting in low mass fraction of manganese acetate or cobalt acetate in the product solution.
[0007] The purpose of the present application can be achieved by the following technical solutions:
[0008] A high-efficiency synthesis method of metal acetate, comprising the following steps:
[0009] The metal element is filled into the reactor, and then acetic acid (liquid pure acetic acid at normal temperature and pressure), hydrogen peroxide and water are mixed to prepare a first solution;
[0010] The first solution is heated to 95-110℃ to obtain a second solution;
[0011] The third solution is pumped into a reactor filled with the metal element, and after staying, the effluent is collected and filtered to obtain the metal acetate.
[0012] The third solution is pumped into a reactor filled with the metal element, and after staying, the effluent is collected and filtered to obtain the metal acetate.
[0013] As a further aspect of the present application, the metal element is any one of cobalt or manganese.
[0014] As a further aspect of the present application, the concentration of hydrogen peroxide is 10wt%-30wt%;
[0015] Further, the concentration of hydrogen peroxide is 10wt%.
[0016] As a further aspect of the present application, the mass ratio of acetic acid, hydrogen peroxide and water is 1:(2-4):(2-4).
[0017] As a further aspect of the present application, the mass ratio of the promoter and the second solution is 1:(100-1000).
[0018] As a further aspect of the present application, the promoter is any one of chloride, bromide or fluoride corresponding to the metal element.
[0019] Further, the promoter is bromide corresponding to the metal element.
[0020] As a further aspect of the present application, the staying time is 10-60s.
[0021] As a further aspect of the present application, the mass fraction of the metal acetate in the effluent is >10%.
[0022] As a further aspect of the present application, the metal acetate obtained by filtration is in the shape of a sheet or a cake.
[0023] Compared with the prior art, the present application has the following advantages:
[0024] 1. The present application provides an efficient synthesis method of metal acetate, specifically an efficient synthesis method of cobalt acetate or manganese acetate. First, acetic acid is used as a reaction medium and ligand to react with metal cobalt / manganese to generate acetate, and hydrogen peroxide is used as an oxidant to oxidize metal cobalt / manganese Co 0 / Mn 0 ) to Co 2+ / Mn 2+, promote dissolution. Water adjusts the concentration of the solution to avoid excessive concentration of acetic acid and hydrogen peroxide, which can cause side reactions such as excessive oxidation or corrosion, and the mass ratio is controlled at 1:(2-4):(2-4): to ensure that the oxidation rate is balanced with the dissolution rate, avoiding excessive decomposition of H2O2 or volatilization of acetic acid. During the heating process to 95-110℃, the temperature rise accelerates the decomposition of hydrogen peroxide to generate active oxygen, improving the oxidation efficiency, while the high temperature promotes the activation of the metal surface, speeding up the reaction kinetics, and the temperature is controlled at the boiling point of acetic acid (≈118℃) to prevent solvent loss due to volatilization; by adding cobalt / manganese halides as accelerators, the activation energy of metal dissolution is reduced, the reaction is accelerated, and trace addition can catalyze the reaction to avoid the introduction of impurities, in addition, cobalt / manganese bromide is superior to other cobalt / manganese halides due to its stronger coordination ability; finally, by continuously flowing the reaction through the pump, the high specific surface area of the metal is used to quickly contact the solution, shortening the reaction time, and short residence time (10-60s) prevents excessive oxidation (such as Co 3+ / Mn 3+ generation) or accumulation of by-products, improving selectivity.
[0025] 2. The present application improves the mass transfer efficiency of cobalt / manganese solid phase and acetic acid / hydrogen peroxide liquid phase by adding a specific accelerator in the reaction system, and the synergistic effect of hydrogen peroxide oxidation and accelerator, making the reaction more complete, thereby significantly increasing the mass fraction of cobalt acetate or manganese acetate in the product solution, which can reach more than 10%, meeting the concentration requirements of finished product sales, without the need for subsequent concentration treatment process, simplifying the production process. Reasonable control of reaction temperature, material residence time and addition ratio of accelerator, etc. accelerates the reaction rate and improves the product output per unit time, which is beneficial to improve the overall production efficiency. Based on the improvement of the acetic acid hydrogen peroxide method, the safety hazards caused by the use of dangerous raw materials in the nitric acid method are avoided, the safety risk in the production process is reduced, the problems of low efficiency and high pollution in the traditional synthesis of cobalt / manganese acetate are solved, and the advantages of high efficiency, green and low cost are combined, which is suitable for industrial production.
