| titleOfInvention | A kind of five (dimethylamino) tantalum synthetic methods |
| abstract | The invention discloses a kind of synthetic methods of five (dimethylamino) tantalums, include the following steps：Tantalic chloride and alkane C are added in the reactor of inert atmosphere protection n H 2n+2 (n >=6) mixture is added dimethylamine and is reacted under stirring conditions, and the temperature of reaction system is maintained at 0~30 DEG C, after being added dropwise, and is kept for 0~30 DEG C react 8 12 hours.N-BuLi alkane C is added dropwise n H 2n+2 (n >=6) solution is maintained at 0~30 DEG C and reacts 4 20 hours, then maintains the reflux for reaction 4 12 hours.It is decompressed to 1000 7000Pa and steams alkane C n H 2n+2 (n >=6) solvent is transferred to doing in sublimator, is decompressed to 50 300Pa and is collected product five (dimethylamino) tantalum.Reagent selected by the method for the present invention is conventional reagent, and inexpensive and be easy to get, operating process is simple, no security risk；The application of snake type sandwich sublimation device, improves product purity and reaction yield；Solvent is reusable needed for reaction, waste is not generated, to environment without any pollution. |
