Embodiment 1

[0022] A kind of preparation method of zirconium acetate, specifically comprises the following steps:

[0023] (1) drop into 1000Kg zirconium carbonate in the enamel reactor;

[0024] (2) Add 750Kg of acetic acid to the enamel reaction kettle of step (1), and then use steam to heat the enamel reaction kettle to increase the temperature of the kettle; ℃; during the heat preservation process, repeated sampling and observation, until completely dissolved and clear, to obtain zirconium acetate solution;

[0025] (3) the zirconium acetate solution obtained in the step (2) is first filtered through 200 mesh filter cloths to obtain the first filtrate, and then the first filtrate is used to obtain the filtrate after two stages of filtration using a microporous filter with an aperture of 1 μm;

[0026] (4) Put the filtrate obtained in step (3) into a crystallization tray, then evaporate and crystallize for 130 hours in a water bath at a constant temperature of 90°C;

[0027] (5) Pack...

Embodiment 2

[0032] A kind of preparation method of zirconium acetate, specifically comprises the following steps:

[0033] (1) drop into 800Kg zirconium carbonate in the enamel reactor;

[0034] (2) Add 600Kg of acetic acid to the enamel reaction kettle of step (1), and then use steam to heat the enamel reaction kettle to increase the temperature of the kettle; when the temperature of the kettle rises to 60°C, stop heating and maintain the temperature of the kettle at 60±2 ℃; during the heat preservation process, repeated sampling and observation, until completely dissolved and clear, to obtain zirconium acetate solution;

[0035] (3) the zirconium acetate solution obtained in the step (2) is first filtered through 200 mesh filter cloths to obtain the first filtrate, and then the first filtrate is used to obtain the filtrate after two stages of filtration using a microporous filter with an aperture of 5 μm;

[0036] (4) Put the filtrate obtained in step (3) into a crystallization tray, a...

Embodiment 3

[0042] A kind of preparation method of zirconium acetate, specifically comprises the following steps:

[0043] (1) drop into 900Kg zirconium carbonate in the enamel reactor;

[0044] (2) Add 675Kg of acetic acid to the enamel reaction kettle of step (1), and then use steam to heat the enamel reaction kettle to increase the temperature of the kettle; ℃; during the heat preservation process, repeated sampling and observation, until completely dissolved and clear, to obtain zirconium acetate solution;

[0045] (3) the zirconium acetate solution obtained in the step (2) is filtered through 200 mesh filter cloths earlier to obtain the first filtrate, and then the first filtrate is used to obtain the filtrate after the two-stage filtration of the microporous filter with an aperture of 3 μm;

[0046] (4) Put the filtrate obtained in step (3) into a crystallization tray, then evaporate and crystallize for 160 h under a constant temperature condition of a water bath at 95° C.;

Abstract

The invention provides a preparation method of zirconium acetate, comprising the steps of (1) charging zirconium carbonate into an enameled reactor; (2) adding acetic acid into the enameled reactor ofstep (1), and heating for dissolving to obtain zirconium acetate solution after clarifying; (3) subjecting the zirconium acetate of step (2) to triple filtering to obtain filtrate; (4) adding the filtrate of step (3) into a crystallizing tray, and performing evaporative crystallization under water bath and constant temperature; (5) cooling the crystallized zirconium acetate to room temperature, and packaging. The zirconium acetate prepared by the preparation method has the advantages of good purity and dissolubility; after the zirconium acetate is dissolved in water, NTU is < / =10, REO(ZrO2) is > / =46%, and all metallic impurity ions of Fe, Ca, Na, K, Pb and Zn are less than 50 ppm.

Description

technical field [0001] The invention relates to the field of rare earth production, in particular to a preparation method of zirconium acetate. Background technique [0002] The main uses of zirconium acetate are: zirconium acetate is widely used in paint drier, fiber, paper surface treatment, building material waterproofing agent, etc. At present, there are not many manufacturers, but the solubility of these manufacturers cannot meet the requirements of customers, and the scattering turbidity value NTU after dissolution exceeds the standard, which cannot fully meet the needs of users. Contents of the invention [0003] The invention provides a preparation method of zirconium acetate, which solves the problems that the existing zirconium acetate has relatively high NTU and unclear dissolution. [0004] The synthesis scheme provided by the invention is as follows: [0005] A preparation method of zirconium acetate, the steps are as follows: [0006] (1) drop into zirconi...
