Recommanded Product: 13940-83-5. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: Nickel(ii)fluoridetetrahydrate, is researched, Molecular F2H8NiO4, CAS is 13940-83-5, about Preparation of high-purity nickel compound from Ni-containing waste materials. Author is Gu, Heng; Li, Xingying; Zhu, Jianchun; Zhou, Jinyun.
The process conditions for the preparation of high-purity Ni compounds (NiSO4.6H2O, NiF2.4H2O, Ni(Ac)2.4H2O, and NiO) from Ni-containing waste carbonate by H2SO4 leaching were studied, and a technol. process was proposed. The principle for the purification and extraction of Ni solution in the system of H2SO4 was discussed with phase diagram. The recovery of Ni was 92%, and the quality of the product met the national standard
