Introduction
Potassium trifluoroacetate is an inorganic compound. It is a colorless crystalline or white powdery solid that is soluble in water and alcohol. The following is an introduction to the properties, uses, preparation methods and safety information of potassium trifluoroacetate:
Quality:
- Potassium trifluoroacetate is highly corrosive and reacts quickly with water and releases toxic hydrogen fluoride gas.
- It is a strong acidic substance that reacts with alkali to produce the corresponding salt.
- It can be oxidized by oxidizing agents to potassium oxide and carbon dioxide.
- Decomposes at high temperatures to produce toxic oxides and fluorides.
- Potassium trifluoroacetate has a corrosive effect on metals and can form fluoride with metals such as copper and silver.
Use:
- Potassium trifluoroacetate is widely used as a catalyst in organic synthesis reactions, especially in fluorination reactions.
- It can be used as an electrolyte additive in ferromanganese batteries and electrolytic capacitors.
- Potassium trifluoroacetate can also be used in metal surface treatment to improve the corrosion resistance of metal surfaces.
Method:
- Potassium trifluoroacetate can be formed by the reaction of trifluoroacetic acid with alkali metal hydroxides.
Safety Information:
- Potassium trifluoroacetate is irritating and should be avoided from contact with skin and eyes.
- Protective gloves, safety glasses and protective clothing should be worn during operation.
- Avoid inhaling its dust or vapour and should use it in a well-ventilated area.
