Manufacturing method

of nickel acetate Nickel acetate is an important raw material for chemical production, which is widely used in electroplating, catalyst, pigment and other fields. This paper will introduce the manufacturing method of nickel acetate, including raw material preparation, reaction process, post-treatment and so on.

1. Raw Material Preparation

Raw materials required for the manufacture of nickel acetate include nickel salts, acetic acid and reducing agents. Among them, nickel nitrate, nickel sulfate or the like can be used as the nickel salt, acetic acid or an organic acid such as acetic acid can be used as the acetic acid, and hydrogen gas, hydrazine hydrate or the like can be used as the reducing agent.

2. reaction process

1. preparation of solution
nickel salt and acetic acid in accordance with a certain proportion of the reaction kettle, stirring evenly, prepared into a certain concentration of solution.

2. reduction reaction
to the reaction kettle into the reducing agent, so that it and the solution of nickel ions in the reduction reaction, the generation of nickel acetate.

3. pH value control
During the reaction, the pH value of the solution needs to be controlled to ensure the normal progress of the reaction. The pH of the solution can be adjusted by adding an acid or a base.

4. Heating the reaction
In order to speed up the reaction rate, the reactor needs to be heated. Generally, water bath heating or electric heating is used.

5. Filtration and Washing
After completion of the reaction, the generated nickel acetate was filtered and washed with distilled water to obtain a nickel acetate product.

3. post-treatment

1. Drying
Put the washed nickel acetate into a drying oven for drying to remove moisture.

2. Packaging
After drying is completed, the nickel acetate is packaged, generally using plastic bags or glass bottles and other containers for packaging.

4. precautions

1. During the operation, it is necessary to pay attention to control the reaction temperature and pH value to ensure the smooth progress of the reaction.

2. The reactor and filter need to be cleaned and maintained regularly to maintain the normal operation and service life of the equipment.

In short, the manufacturing method of nickel acetate is not complicated, but it is necessary to pay attention to the control of reaction conditions and equipment maintenance to ensure the quality of the product and the smooth progress of production.
