Recommanded Product: Nickel(ii)fluoridetetrahydrate. The mechanism of aromatic electrophilic substitution of aromatic heterocycles is consistent with that of benzene. Compound: Nickel(ii)fluoridetetrahydrate, is researched, Molecular F2H8NiO4, CAS is 13940-83-5, about Thermal decomposition of nickel and zinc fluoride tetrahydrates. Author is Lange, Bruce A.; Haendler, Helmut M..
NiF2.4H2O decomposes in 3 steps when heated. In dry air or Ar atm. NiF2.H2O is formed at ∼125°, but H2O and HF are lost and NiOHF.3NiF2 is formed at ∼225°. NiOHF.3NiF2 loses another mol. of HF at ∼430° and the final product is a mixture of NiF2 and NiO in 3:1 mole ratio. In the presence of H2O, the final product is NiO, the other steps being the same. ZnF2.4H2O loses H2O at >75° to give anhydrous ZnF2.
