Embodiment 1

[0031] The technique of producing nickel acetate by ion exchange method comprises the following steps

[0032] Step 1: Resin Transformation

[0033] Sodium hydroxide is configured into a solution with a mass concentration of 5%. When the temperature of the solution drops below 40 degrees Celsius, the solution enters from the upper end of the ion exchange column at a speed of 2 m / hour and then recovers the outflowing solution for the next configuration of alkali Liquid, the transformation consumption of solution is the volume of 2 times of resin;

[0034] Step Two: Wash

[0035] Use deionized water with a conductivity of less than 10μs / cm to enter from the upper end of the ion exchange column to wash the lye in the ion exchange column, and the washing water is recovered for the preparation of lye;

[0036] Step Three: Ion Exchange

[0037] Pass the nickel salt solution of any concentration through the resin layer at a flow rate of 10 m / h in the ion exchange column, the sodiu...

Abstract

The invention discloses a technology for producing nickel acetate through an ion exchange method. According to the ion exchange method for producing nickel acetate, ion exchange resin, ion exchange columns, glacial acetic acid, alkali and deionized water are involved. The method comprises the production steps of transition, adsorption and elution of ion exchange resin and the like. According to the implementation scheme, the technology route for producing nickel acetate is simple, cost is low, and continuous production can be achieved.

Description

technical field [0001] The invention relates to a process for producing nickel acetate by an ion exchange method, belonging to the field of chemical industry. Background technique [0002] As an important chemical product, nickel acetate is mainly used in petrochemical catalysts. Most of the current production adopts 1. Synthesize nickel salt into basic nickel carbonate or nickel hydroxide and react with glacial acetic acid to produce nickel acetate, and finally produce nickel acetate through concentrated water crystallization. 2. Using metal nickel and glacial acetic acid to react under the catalysis of hydrogen peroxide to produce nickel acetate solution, and finally produce nickel acetate through concentrated crystallization. The above production process cannot realize continuous production. Contents of the invention [0003] The purpose of the invention is to provide a process for producing nickel acetate by an ion exchange method, which can realize automatic and con...
