Nickel acetate is an important raw material for chemical production, which is widely used in many fields. This article will detail the properties and uses of nickel acetate.
1. the properties of nickel acetate
Nickel acetate is an inorganic compound with the chemical formula Ni(CH3COO)2, usually a green or blue crystalline powder. It has the following properties:
1
Solubility: nickel acetate soluble in water and ethanol, slightly soluble in ether and benzene.
2. Acidity: Nickel acetate has a certain acidity and can react with alkali to generate the corresponding salt.
3. Thermal stability: Nickel acetate will decompose to generate nickel oxide and acetic acid when heated.
4. Toxicity: Nickel acetate has certain toxicity, inhalation or excessive intake of nickel acetate may cause harm to human health.
2. the use of nickel acetate
nickel acetate in many fields have a wide range of applications, the following lists some of the main uses:
1. catalyst: nickel acetate can be used as a variety of organic synthesis reaction catalyst, such as hydrogenation reaction, dehydrogenation reaction, oxidation reaction.
2. Electroplating: Nickel acetate can be used as the main component in the electroplating solution for nickel plating to improve the corrosion resistance and appearance quality of the material.
3. Pigment: Nickel acetate can be used as green pigment in paint, ink and other fields.
4. Battery: Nickel acetate can be used to prepare nickel-cadmium batteries, nickel-hydrogen batteries, etc., with high energy density and stability.
3. of nickel acetate production
of nickel acetate production methods are mainly two: one is through the reaction of nickel and acetic acid to generate nickel acetate; the other is through the reaction of nickel oxide and acetic acid to generate nickel acetate. Among them, the first method is more commonly used, and the specific steps are as follows:
1. cut metal nickel into small pieces and add them into a reaction kettle;
2. add excess acetic acid and heat the reaction;
3. after the reaction, filter out unreacted metal nickel to obtain a nickel acetate solution;
4. evaporate and concentrate the nickel acetate solution to obtain a nickel acetate crystal.
Precautions for storage and use of nickel acetate in
4.
1. Storage: Nickel acetate should be stored in a dry, cool, well-ventilated place, away from direct sunlight and high temperature.
2. use: in the use of nickel acetate, should pay attention to maintain good ventilation, avoid inhalation or contact with the skin. In case of accidental contact, rinse with water immediately and seek medical examination.
In short, nickel acetate, as an important raw material for chemical production, has been widely used in many fields. Understanding the properties and uses of nickel acetate is of great significance to the rational use of resources, the improvement of production efficiency and the protection of human health.
