| titleOfInvention | Synthesis method of tetra (dimethylamino) zirconium |
| abstract | The invention discloses a synthetic method of tetra (dimethylamino) zirconium, which comprises the following steps: (1) under the protective atmosphere, mixing zirconium tetrachloride with an alkane solvent to obtain a mixed solution; (2) introducing dimethylamine into the mixed solution at the temperature of minus 20 ℃ to minus 10 ℃ to obtain a reaction solution after reaction; (3) adding dialkyl amine into the reaction liquid at the temperature of minus 20 ℃ to minus 10 ℃ to react; wherein the dialkylamine is diethylamine, di-n-propylamine, diisopropylamine, di-n-butylamine or di-iso-butylamine; (4) and distilling under reduced pressure to collect fractions to obtain the zirconium tetra (dimethylamino) chloride. The synthetic method of the tetra (dimethylamino) zirconium provided by the invention does not need to use organic metal compounds which are self-ignited in the air and have extremely high operation risk coefficient, thereby greatly improving the production safety; meanwhile, the raw material cost can be effectively reduced, the generation of waste liquid is reduced, the production period of the zirconium tetra (dimethylamino) is shortened, the yield is improved, and the large-scale production is facilitated. |
