What is the preparation method of antimony trifluoride

The method of preparation of antimony trifluoride, that is, antimony trifluoride, has been different throughout the ages, and it is now one of the king's methods.

It is often prepared by direct combination of antimony and fluorine. However, fluorine is extremely active, highly corrosive and toxic, and extreme caution is required when operating. The reaction is as follows: 2Sb + 3F

. The reaction is violent and often needs to be carried out in a special reactor, and the reactor needs to be able to withstand fluorine attack.

can also be prepared by reacting antimony trioxide with hydrofluoric acid. First take an appropriate amount of antimony trioxide, put it in an acid-resistant container, and slowly add hydrofluoric acid. The reaction is as follows: Sb 2O + 6HF < unk > 2SbF < unk > + 3H < unk > O. This reaction is relatively mild, but hydrofluoric acid is also highly corrosive. During the operation, the protection should not be slack. During the reaction process, the reaction needs to be constantly stirred to make the reaction fully proceed. After the reaction, pure antimony trifluoride can be obtained by means of evaporation, crystallization, etc.

Preparation of antimony trifluoride, no matter what method, safety is the first priority, and protective measures must be comprehensive in order to successfully prepare the required material.
