| titleOfInvention | The production method of tetrakis (dimethylamine) zirconium |
| abstract | The invention relates to the technical field of preparation and production of organic substances, and discloses a production method of tetrakis(dimethylamine) zirconium, which comprises the following steps: S1: adding toluene, adding zirconium tetrachloride into a reaction kettle at one time, and simultaneously adding no Water-treated toluene, and it is subjected to cooling treatment; S2: ventilation, feed dimethylamine gas under stirring conditions, to form a color solution; S3: stirring reaction, in S2, ventilation ends, and continues to be stirred for 8-16 hour; S4: dropwise add the solution, keep the temperature at -60 to -30 degrees Celsius at the end of the reaction, and add n-butyllithium-n-hexane solution dropwise. The invention can not only improve the dissolution effect by fully stirring, but also can use nitrogen as a protective gas to form an inert space in the reaction kettle, improve safety, avoid material oxidation, and can also simplify the operation process and avoid batch feeding. Contact possibility, and at the same time, the use of toluene can improve the reaction yield and reduce the cost. |
