Synthesis method of bi(2-aminoisobutyl)amine

The invention relates to a synthesis method of bi(2-aminoisobutyl)amine. According to the method provided by the invention, 2-aminoisobutanol and an ammoniation agent are used as raw materials and arecatalytically synthesized into the bi(2-aminoisobutyl)amine under a hydrogen gas condition; the method comprises the following steps: (1) adding the 2-aminoisobutanol, the ammoniation agent and a catalyst into a high-pressure kettle; (2) introducing a certain amount of hydrogen gas and reacting for 6h to 15h under the condition that the temperature is 160 DEG C to 200 DEG C; (3) after reaction isfinished, filtering to remove the catalyst and rectifying a reaction solution to obtain a pure product of the bi(2-aminoisobutyl)amine. With the adoption of the method, a synthesis process is clean and simple to operate; a target product can be obtained through one-step reaction and the synthesis method is applicable to large-scale preparation.
