COPPER(II) FLUORIDE-2-HYDRATE - Introduction
Copper (II) fluoride dihydrate, molecular formula CuF2 · 2H2O, is a pale blue crystal. Its nature is as follows:
1. nature:
-Appearance: Copper (II) fluoride dihydrate is a light blue crystal, mostly amorphous powder or granular.
-Melting point: about 100-110 degrees Celsius.
-Solubility: Soluble in water, insoluble in alcohol and ether.
-Stability: relatively stable in the air, but decomposed by heat to produce toxic hydrogen fluoride gas.
2. use:
-Metallurgical industry: used as a catalyst for copper smelting.
-Chemical laboratory: It can be used to prepare other copper-containing compounds and organic copper reagents.
-Electronics industry: used as a colorant for optical glass and ceramic materials.
-other applications: can be used in battery, electroplating, medicine and other fields.
3. Preparation method:
Copper (II) fluoride dihydrate can be prepared by the following two methods:
-Copper fluoride and water react to produce.
-Copper chloride and potassium fluoride reaction.
4. Safety Information:
-Copper fluoride is toxic and should be avoided by inhalation or contact with skin, eyes and mucous membranes.
-Copper fluoride dust can cause respiratory and digestive tract irritation, may lead to gastrointestinal discomfort, nausea, diarrhea and other symptoms.
-During the operation, necessary protective measures should be taken, such as wearing gloves, goggles and protective clothing.
-When using copper (II) fluoride dihydrate, pay attention to comply with relevant safety procedures, and properly store and dispose of waste. In case of discomfort or accident, seek medical assistance immediately.
