-
Paragraph 0028; 0030, (2017/12/01)
The invention discloses a preparation method of fluorozirconate. The preparation method comprises the following steps of A, enabling a nitrogen-containing heterocyclic compound and halogenating alkane to be subjected to a reaction in an organic solvent under alkaline conditions, so as to obtain heterocyclic amine based alkane halogen; B, enabling the heterocyclic amine based alkane halogen obtained in the step A to be dissolved in an organic solvent, and performing heating so as to obtain nitrogen spirane halide salt; and C, enabling nitrogen spirane halide salt which is obtained in the step B and as shown in a formula iv to be dissolved in the organic solvent, and performing ion exchange on the nitrogen spirane halide salt dissolved in the organic solvent with pentafluoro sodium zirconate or pentafluoro zirconic acid so as to obtain nitrogen spirane pentafluoro zirconic acid as shown in a formula vi, or performing ion exchange on the nitrogen spirane halide salt dissolved in the organic solvent with hexafluorozirconic acid or hexafluorozirconic acid sodium so as to obtain dinitrogen spirane hexafluorozirconic acid salt as shown in a formula vi. According to the method disclosed by the invention, raw materials are cheap and easy to obtain, reaction steps are simple, the yield is high, pollution is hardly generated, strict and dangerous reaction conditions are not used, products are easy to refine, and the method disclosed by the invention is suitable for national mass production.
