| Tin(iv) Fluoride Usage And Synthesis |
| Chemical Properties | Stannic Fluoride or tin(iv) fluoride, is an inorganic tin fluoride compound, and generally a off-white powder. It is hygroscopic and has a melting point of 700 C or higher, well above the melting points of other tin(iv) halides. | | Uses | Friedel-Crafts catalyst. | | Uses | It is used as Friedel-Crafts catalyst. | | Preparation | Stannic fluoride can be prepared from the reaction of fluorine, chlorine trifluoride, or bromine trifluoride with tin(II) or tin(IV) compounds. It acts as a Lewis acid to form many complexes. It is used in the manufacture of glasses. | | Reactions | Stannic fluoride combines with ammonia and other bases, and also with alkali and other fluorides to form stannifluorides of the type M2SnF6. Stannic fluoride forms with ammonia at 43° C. the white solid SnF4.NH3, which can be heated to 400° C. with loss of very little ammonia; the compound SnF4.2NH3 is formed when stannic fluoride and ammonia are heated in a sealed tube at 120°-130° C. Both compounds dissolve in water, but their solutions gradually decompose. Aniline, pyridine, and quinoline also form additive compounds with stannic fluoride. |
